Amphibians from Liberia and the Gold Coast
Provedor de dados: 16
Autores: Parker, H.W.
Thanks to the courtesy of Drs. Boschma and Brongersma the author has been privileged to examine a large series of West African amphibians from the collections of the Royal Museum of Natural History in Leiden. Of the comparatively easily accessible parts of Africa, Liberia is probably the least known, in so far as its herpetological fauna is concerned, and consequently it is not surprising to find that the present material contains much of interest. The following notes concern some of the more obvious points which arise out of the material examined and do not purport to be in any way exhaustive. The author is indebted not only to the gentlemen already mentioned, but also to M. Angel and Mr. Loveridge who have most generously placed at his disposal material...

High amphibian diversity related to unexpected environmental values in a biogeographic transitional area in north-western Mexico
Provedor de dados: 16
Autores: Serrano, J.M.; Berlanga-Robles, C.A.; Ruiz-Luna, A.
Amphibian diversity and distribution patterns in Sinaloa state (north-western Mexico) were assessed from the Global Amphibian Assessment database (GAA-2010). A geographic information system (GIS) was used to evaluate diversity based on distribution maps of 41 species, associated with environmental data. The highest α and γ-diversities were identified in the south-eastern portion of the state, in mountain zones with a warm sub-humid climate, whereas the greatest β-diversity (multiplicative formulation) was aggregated in patches in the western portion of the state in mountains with temperate climates. A cluster analysis and Mantel test showed a strong association of Sorensen’s dissimilarity (additive formulation of β-diversity) with climate and soil moisture...

A new cryptic species of lizard (Sauria: Teiidae: Gymnophthalmus) from Venezuela
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Cole, C.J.; Ayarzaguena, J.
Gymnophthalmus cryptus spec. nov. is described and illustrated on the basis of males and females collected in the Territorio Federal Amazonas, southern Venezuela. Some details on ecology and distribution are also presented. The females of G. cryptus are very similar to the unisexual Gymnophthalmus underwoodi, which also occurs in the Guianan Region. In fact, G. cryptus is one of the best candidates for future genetic research to determine whether it is the missing ancestor of G. underwoodi, a parthenogenetic species of hybrid origin (G. speciosus x G. spec.?). Two other series of previously unreported species of Gymnophthalmus from Venezuela are also discussed.

Three new species of the genus Adelophryne (Amphibia: Anura: Leptodactylidae) from northeastern Brazil, with remarks on the other species of the genus
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Borges, D.M.; Cascon, P.
In the present paper three new species of the genus Adelophryne from the coastal Atlantic forest in Brazil are described. The species are separated from the two species formerly known from the Amazon forest by caatinga vegetation and a distance of at least 1600 km. A. pachydactylus from Bahia has a reduced number of phalanges in the fourth finger, and large subdigital pads under fingers and toes. A. baturitensis has distinct subarticular tubercles under the toes and a relatively large size. A. maranguapensis has large discs on fingers and toes and is boldly patterned. During fieldwork in Amapá two specimens of A. gutturosa were collected and based on them additional data are provided and some concepts from the original description are revised. Literature...

Resurrection of Hyla wavrini Parker (Amphibia: Anura: Hylidae), a gladiator frog from northern South America
Provedor de dados: 16
Autores: Hoogmoed, M.S.
During field work in Venezuela and Brazil a difference in call was noticed between specimens of large hylids of the Hyla boans-group. Based on this and on morphological differences, it was concluded that Hyla wavrini Parker, 1936, up till now considered a synonym of Hyla boans (Linnaeus, 1758), should be considered a valid species, of which Hyla miranda-ribeiri Melin, 1941 is a synonym. Durante trabajo de campo en Venezuela y el Brasil se nota una diferencia en el canto de especimenes de gran Hílidos del grupo Hyla boans. Basandose en este observación y en diferencias morfológicas, se concluye que Hyla wavrini, considerado até horita como sinónimo de Hyla boans debe ser considerado como especie valido, y que Hyla miranda-ribeiri es un sinónimo de el....

An investigation into the taxonomy of Dendrelaphis tristis (Daudin, 1803): revalidation of Dipsas schokari (Kuhl, 1820) (Serpentes, Colubridae)
Provedor de dados: 16
Autores: Rooijen, J. van; Vogel, G.
The taxonomic status of the colubrid snake Dendrelaphis tristis (Daudin, 1803) was investigated on the basis of morphological data taken from 64 museum specimens. Univariate and multivariate analyses of these data reveal that Dendrelaphis tristis is composed of two species. One of these species agrees with the description of Dipsas schokari Kuhl, 1820 which is revalidated in the combination Dendrelaphis schokari (Kuhl, 1820). The syntypes of D. schokari have been lost and a type for D. tristis has never been deposited in a collection. Neotypes are designated and described for both species in order to stabilize the names. D. schokari differs from D. tristis in having a lower number of ventrals and subcaudals, a larger eye, a shorter vertebral stripe and the...

Spectral transmittance of the spectacle scale of snakes and geckos
Provedor de dados: 16
Autores: Doorn, K. van; Sivak, J.G.
The spectral transmittance of the optical media of the eye plays a substantial role in tuning the spectrum of light available for capture by the retina. Certain squamate reptiles, including snakes and most geckos, shield their eyes beneath a layer of transparent, cornified skin called the ‘spectacle’. This spectacle offers an added opportunity compared with eyelidded animals for tayloring the spectrum. In particular, the hard scale that covers the surface of the spectacle provides a unique material, keratin, rarely found in vertebrate eyes, a material which may have unique spectral properties. To verify this, shed snake and gecko skins were collected and the spectral transmittance of spectacle scales was spectrophotometrically analyzed. The spectacle scale...

Les espèces Ouest-Africaines du genre Lycophidion (Serpentes, Colubridae)
Provedor de dados: 16
Autores: Guibé, J.; Roux-Estève, R.
Il règne une certaine confusion dans la systématique des serpents africains du genre Lycophidion et, malgré les tentatives de divers auteurs, l'identification des espèces s'avère souvent difficile et aléatoire; tel est le cas des formes de l'ouest-africain où il semble que certaines espèces ou sous-espèces aient été méconnues. Nous entendons par ouest-africain la région au nord du golfe de Guinée, limitée à l'Est par les hauteurs du Nord Cameroun jusqu'aux environs du lac Tchad. D'après les travaux récents, le genre Lycophidion est représenté dans cette région par les espèces suivantes: L. irroratum (Leach), L. semicinctum D. &amp; B., L. laterale Hallowell, auxquels Leston &amp; Hughes (1968), Hughes &amp; Barry (1969) et Leston (1970) ajoutent L....

Genealogy of the nuclear β-fibrinogen intron 7 in Lissotriton boscai (Caudata, Salamandridae): concordance with mtDNA and implications for phylogeography and speciation
Provedor de dados: 16
Autores: Teixeira, J.; Martínez-Solano, I.; Buckley, D.; Tarroso, P.; García-París, M.; Ferrand, N.
The power of phylogeographic inference resides in its ability to integrate information from multiple sources in an iterative hypothesis-testing framework. In this paper, we build upon previous mtDNA-based hypotheses about the evolutionary history of the Iberian newt Lissotriton boscai using sequences of the highly variable nuclear β-fibrinogen intron 7. In addition to the nuclear sequences, we produced new mtDNA data across the species range to delineate contact zones and test the congruence between nuclear and mitochondrial datasets at the same level of spatial organization. Through a combination of phylogenetic, phylogeographic continuous diffusion, and genetic landscape modelling analyses, we infer the evolutionary history of the species. We found...

On a new species of toad from southern Morocco
Provedor de dados: 16
Autores: Hoogmoed, M.S.
A new species of toad, related with Bufo calamita Laurenti and B. viridis Laurenti, is described from the southern part of Morocco. Combining the data of the available specimens with literature records it was established that the new species probably ranges from the Sous valley southwards to Cape Bojador in the Spanish Sahara. The species seems to be restricted to semi-arid habitats. Tadpoles which probably belong to this species are described. Keys for the identification of adult toads and for the tadpoles are given.

Lizards with northern affinities from the mountains of Oman
Provedor de dados: 16
Autores: Arnold, E.N.
Oman material of four lizard species is described and discussed ; it comprises specimens of a previously undescribed gecko, Phyllodactylus gallagheri, two lacertids — the poorly known Lacerta jayakari Boulenger, 1887, and L. cyanura, also described here for the first time, and a skink, Ablepharus pannonicus Lichtenstein, 1823. These species have no strong affinities with any members of the mainly Saharo-Sindian fauna now occupying much of Arabia but are closely related to forms occurring to the north of the peninsula. It is probable that they are relicts of a more temperate fauna which once entered more extensively into southeastern Arabia. As might be expected, all four species are absent from the desert areas of Oman and are confined to the disjunct...

Variation in skull size and shape of the Common wall lizard (Podarcis muralis): allometric and non-allometric shape changes
Provedor de dados: 16
Autores: Urošević, A.; Ljubisavljević, K.; Ivanović, A.
We analysed patterns of skull size and shape variation among populations of the Common wall lizard (Podarcis muralis) in the Central Balkans, particularly the effecs of insularity and the presence of the ecologically similar lacertid lizard species P. melisellensis. Two components of shape variation were analysed – size dependent (allometric) and size independent shape changes. The observed shape differentiation relating to insularity was greatly size-dependent and concordant to allometric shape changes which explained over 20% of variation in the skull shape in the analysed sample. The explorative analysis of size-independent shape changes revealed that populations of P. muralis which share habitat with P. melisellensis diverge from populations which do...

Varanus (Reptilia, Sauria) from the Pleistocene of Timor
Provedor de dados: 16
Autores: Hooijer, D.A.
The present note deals with two varanid vertebrae from Pleistocene gravel deposits at Raebia in the Atambua area of Indonesian Timor. The specimens were collected in 1966 by Dr. Th. Verhoeven, who gave them to me for study. Other fossil vertebrate remains from the same site belong to a giant land tortoise, Geochelone atlas (Falconer &amp; Cautley) also known from the Pleistocene of India, Java and the Celebes (Hooijer, 1971), and Stegodon timorensis Sartono, a pygmy proboscidean comparable to those of the Pleistocene of the Celebes and Flores (Hooijer, 1972). No further remains of the varanid have been discovered, and the vertebrae may here be placed on record. There are a thoracic vertebra, with the neural spine broken off and the condyle as well as the...

A revision of the Genus Scincella (Reptilia: Sauria: Scincidae) of asia, with some notes on its evolution
Provedor de dados: 16
Autores: Ouboter, P.E.
Of the genus Scincella Mittleman, 1950 (sensu Greer, 1974) 337 specimens from Asia were examined for 74 characters, which were treated in a numerical-taxonomic way. The dendrogram resulting from this analysis was not stringently adhered to. Because of the wide variation in certain numerical scale characters within one taxon or even within one population, these characters (used by many authors as key characters to separate taxa) are not regarded as very important. For sympatric and parapatric species other characters, including relative size of head, body and limbs, are regarded as very important, because these characters are influenced by the way of life (niche separation). For the separation of allopatric species scale-numbers, but many other characters...

Morphological re-evaluation of the parotoid glands of Bufo ictericus (Amphibia, Anura, Bufonidae)
Provedor de dados: 16
Autores: Almeida, P.G. de; Felsemburgh, F.A.; Azevedo, R.A.; Brito-Gitirana, L. de.
Multicellular glands in the amphibian integument represent a signifi  cant evolutionary advance over those of fi shes. Bufonids have parotoid glands, symmetrically disposed in a post-orbital position.  Their secretion may contribute to protection against predators  and parasites. This study provides a re-evaluation of the morphology  of the Bufo ictericus parotoid glands. The parotoid gland  integument of the medial surface shows rounded depressions  with small pores that connect with the duct openings of the larger  granular glands. Under light microscopic evaluation the integument  is constituted by typical epidermis, supported by dermis  subdivided into a spongious dermis, a reticular dermis, and a  compact dermis. The Eberth-Katschenko layer is...

Some remarks on the Pulmonary Artery in snakes with two lungs
Provedor de dados: 16
Autores: Brongersma, L.D.
The respiratory organs of snakes show a great diversity according to genera and species. In the Boidae (two genera excepted; cf. Brongersma, 1951 a and 1951 b), and in Xenopeltis unicolor (Reinw.) both lungs are well developed, although the left is shorter than the right (Butler, 1895). The difference in length between the right and the left lung is not the same in all genera and species, but it also shows individual variations within the species. In the Anilidae the left lung has undergone further reduction than in the Boidae; in Cylindrophis rufus (Laur.) the left lung is still rather well developed, its length is 12% of that of the right lung; in Anilius scytale (L.) the left lung is rudimentary, its length being only 3.5% of that of the right lung; in...

Drastic population size change in two populations of the Golden-striped salamander over a forty year period - are eucalypt plantations to blame?
Provedor de dados: 16
Autores: Arntzen, J.W.
Over the last half century the Iberian peninsula has seen the large scale planting of exotic gum trees (Eucalyptus sp.) therewith reducing space for native wildlife. An additional effect of the gum tree plantations may be the lowering of the water table in adjacent streams, to which amphibian species with a larval niche in the running sections of small streams would be especially susceptible. In northwestern Iberia that niche is occupied by the Golden-striped salamander, Chioglossa lusitanica. I here report on the demographic trends of two C. lusitanica populations over a forty year period, in two areas of one mountain range near Porto in northwestern Portugal. In both areas advantage was taken of the migration pattern of C. lusitanica to sites for...

The anatomy of Xenopeltis unicolor
Provedor de dados: 16
Autores: Bergman, R.A.M.
General aspect. Xenopeltis unicolor Reinwardt is a burrowing snake, living in South East Asia and in Indonesia. It is easily recognisable even at first sight, both by its peculiar colouring and by the shape of the head, which shows a dorso-ventrally flattened snout, with a curiously rounded frontal margin. Haas (1930) is right in stating that there is probably no other snake with such a remarkable 'physiognomy'. In its way of moving around it seems not to lift the head before going on, but rather to shove it sideways to right and left and then proceed on its way. The scales are very flat and make a completely smooth covering for the animal, this being considered another adaptation to the burrowing life. The name Xenopeltis, however, does not refer to this...

Historical biogeography of Western Palaearctic pelobatid and pelodytid frogs: a molecular phylogenetic perspective
Provedor de dados: 16
Autores: Veith, M.; Fromhage, L.; Kosuch, J.; Vences, M.
Spadefoot toads (Pelobates) and Parsley frogs (Pelodytes) are an enigmatic group of Western Palaearctic anurans. In the genus Pelobates, a fossorial lifestyle has enforced a conserved bauplan that masks their intraspecific evolutionary history. We used partial sequences of the mitochondrial 16S and 12S rRNA genes to infer a paleobiogeographic scenario of speciation events in these two anuran genera. Based on two alternative, mutually exclusive calibrations of the Iberian-African split within Pelobates (Pb. cultripes and Pb. varaldii), the disjunction of the Betic Cordillera ca. 14-16 million years ago (mya), and the end of the Messinian Salinity crisis 5.33 mya, we inferred alternative scenarios for species evolution within both genera applying...

Nomenclatural problems relating to Atractus trilineatus Wagler, 1828

INTRODUCTION The Rijksmuseum van Natuurlijke Historie material of Brachyorrhos albus (L., 1758), which had been on loan to Dr. S. B. McDowell, New York, was returned to us with the remark that reg.no. RMNH 48 from Java certainly did not belong to that species. Dr. McDowell suggested it might be an Atractus, and following his suggestion I examined this specimen. It soon became evident that Dr. McDowell had been right and that the specimen did belong to Atractus trilineatus Wagler, a species only known from Trinidad, eastern Venezuela and western Guyana (Hoogmoed, 1979: 275).  HISTORY The specimen concerned (RMNH 48) belongs to the oldest part of the collection of the RMNH. It turned out to have been investigated by many ancient authors and it was discovered...

The construction for feeding in Rattlesnakes
Provedor de dados: 16
Autores: Dullemeijer, P.; Povel, G.D.E.
INTRODUCTION A controversial point in the understanding of the feeding mechanism of viperid snakes is the use of the poison fang in the swallowing mechanism. Some authors believe that the poison fang takes an active part in the swallowing act, although the majority supports the view that the fang is, at least partly, held down (Klauber, 1956). Which kind of construction in the jaws is responsible for the difference between the actions of the fang in striking and swallowing again is a matter of dispute. The pterygoid-ectopterygoid joint, which by most authors (Kathariner, 1900; Willson, 1908; Haas, 1931; Klauber, 1939, 1956) is considered stiff or immovable, may play a crucial role. There is also some disagreement on the strike being either a stab (Van...

On The Identity Of Some Toads Of The Genus Bufo From Ecuador, With Additional Remarks On Andinophryne Colomai Hoogmoed, 1985 (Amphibia: Anura: Bufonidae).
Provedor de dados: 16
Autores: Hoogmoed, M.S.
Study of the type specimens of B. caeruleostictus Günther, 1859 and B. chanchanensis Fowler, 1913, and of fresh material showed that B. chanchanensis is a junior subjective synonym of B. caeruleostictus. Probably it is a member of the B. guttatus group. B. caeruleocellatus Fowler, 1913 is a junior subjective synonym of B. haematiticus Cope, 1862. New material of B. hypomelas Boulenger, 1913 is reported from NW Ecuador, the species is redescribed, and it is shown that this is a valid taxon, not the juvenile of B. blombergi Myers &amp; Funkhouser, 1951 as suggested by Lynch, in Frost (1985). It is doubted whether B. intermedius Günther originates from Ecuador. It probably is a Central American or Mexican species of the B. valliceps Wiegmann, 1833 group. A...

Estimating the snake species richness of the Santubong Peninsula (Borneo) in two different ways
Provedor de dados: 16
Autores: Rooijen, J. van.
The distribution of Borneo’s species across the island is far from well-known. This is particularly true for snakes which are hard to find. Given the current rate of habitat destruction and consequent need for conservation strategies, more information is required as to the species composition and richness of specific areas of potential conservation priority. An example is the Santubong Peninsula, Sarawak, Malaysia, part of which has recently been gazetted as a National Park. In this paper, the snake species richness of the Santubong Peninsula is estimated on the basis of data obtained during 450 survey-hours. Thirty-two species were recorded. Negative exponential and Weibull functions were fitted to the rarefaction curve. The Weibull function exhibited a...

Autores: Williams, E.
In 1908 Prof. E. Dubois cited and very briefly diagnosed a new species of emydine turtle, Hardella isoclina, from the Trinil Beds in Java. The very fine unique type shell has never been figured or fully described, the generic assignment appears to be incorrect, and the original diagnosis is insufficient. Prof. Boschma and Dr. Brongersma of the Rijksmuseum van Natuurlijke Historie in Leiden have, as custodians of the Dubois Collection, very generously offered me the opportunity of redescribing this form. The fossil is a very distinct species and a very noteworthy component of the Trinil fauna but even after much study and comparison it proves impossible to refer it with confidence to any known genus, and in the absence of any knowledge of the characters of...

Snakes of Sulawesi: checklist, key and additional Biogeographical remarks
Provedor de dados: 16
Autores: Bosch, H.A.J. in den.
A checklist with concise synonymy and a key to the snakes of Sulawesi is presented, comprising 63 species in 38 genera; 3 subspecies and 15 species, of which one constitutes a monotypic genus, are considered endemic. There is a strong Indo-Malayan relationship. Sea-snakes and Candoia carinata excluded, no Philippine, Papuan or Australian affinities were found. Geological and ecological barriers, together with a low immigration pressure from the south and east, are considered causal factors. Although Sulawesi has been an instable island region at least since the Late Cretaceous as compared with most surrounding islands, which were parts of Sundaland or Sahulland and as such were formed relatively recently, the species richness in Wallacea is of the same...

A new scincid lizard of the genus Leiolopisma from New Guinea
Provedor de dados: 16
Autores: Zweifel, R.G.
The lizard fauna of New Guinea numbers over 150 species (for a list, now well out-dated, see Loveridge, 1948), and probably more than two-thirds of these belong to the family Scincidae. With the exception of studies by Brown (1953, 1954) on the genus Emoia, the large and diverse scincid fauna has received little attention from herpetologists since De Rooij (1915) summarized existing knowledge. The validity of many named forms is questionable, and details of distribution and ecology are known for virtually none. The purpose of the present paper is to describe an evidently unnamed species that has been confused with a widespread Papuan species, Leiolopisma miotis.

On the following pages I give a list of the snakes collected by Mr. Edw. Jacobson, during various excursions, which he made in the Padang Highlands and in the country of Korintji. Mr. Jacobson, to whom the Leiden Museum is already indebted for many valuable collections of East-Indian animals, kindly presented these snakes to our Museum. The collection though not a large one is a very valuable one, and proves the importance of a careful investigation of the fauna of CentralSumatra. Of the 36 species, 2 species and one variety are new to science, viz. Pseudoxenodon Jacobsonii, Calamaria crassa, and Simotes annulifer Blgr. var. annulata.

How complex is the Bufo bufo species group?
Provedor de dados: 16
Autores: Arntzen, J.W.; Recuero, E.; Canestrelli, D.; Martínez-Solano, I.
Species delineation remains one of the most challenging tasks in the study of biodiversity, mostly owing to the application of different species concepts, which results in contrasting taxonomic arrangements. This has important practical consequences, since species are basic units in fields like ecology and conservation biology. We here review molecular genetic evidence relevant to the systematics of toads in the Bufo bufo species group (Anura, Bufonidae). Two studies recently published in this journal (Recuero et al., MPE 62: 71–86 and Garci´a-Porta et al., MPE 63: 113–130) addressed this issue but reached opposing conclusions on the taxonomy of the group (four versus two species). In particular, allozyme data in the latter paper were interpreted as...

Comparative tadpole morphology in three species of frogs of the genus Spinomantis (Amphibia: Mantellidae)
Provedor de dados: 16
Autores: Vejarano, S.; Thomas, M.; Vences, M.
We describe the tadpoles of three species of Malagasy frogs, classified in the genus Spinomantis, based on specimens identified by DNA barcoding. The tadpole of Spinomantis aglavei is a typical Orton type IV larva. The oral disc is not emarginated laterally, but has two mid-ventral folds and a labial tooth row formula of 3(2- 3)/2(1). The tadpole of S. phantasticus is similar, the oral disc being laterally emarginated and having one medial fold; LTRF is 3/3(1). A third species, S. cf. fimbriatus is also similar to the other two species; the oral disc is not laterally emarginated but has three medial folds and LTRF is 3(2-3)/3(1). One shared character is a median fold or emargination in the lower part of the oral disc, although the shape of this fold is...

Diversity, external morphology and ‘reverse taxonomy’ in the specialized tadpoles of Malagasy river bank frogs of the subgenus Ochthomantis (genus Mantidactylus)
Provedor de dados: 16
Autores: Randrianiaina, R.-D.; Strauß, A.; Glos, J.; Glaw, F.; Vences, M.
We provide detailed morphological descriptions of the tadpoles of Malagasy river bank frogs of the subgenera Ochthomantis and Maitsomantis (genus Mantidactylus, family Mantellidae), and data on relative abundance and habitat preferences of Ochthomantis species from Ranomafana National Park in southeastern Madagascar. Our study includes the tadpoles of six described and four undescribed candidate species. Eight of these larvae were previously unknown. Tadpoles were identified by DNA barcoding. Due to the very rudimentary taxonomic knowledge on Ochthomantis, we followed a ‘reverse taxonomy’ approach in which adult classification was to a great part determined on the basis of larval differences. By this procedure we even identified one candidate species whose...

Analysis of a herpetofaunal community from an altered marshy area in Sicily; with special remarks on habitat use (niche breadth and overlap), relative abundance of lizards and snakes, and the correlation between predator abundance and tail loss in lizards
Provedor de dados: 16
Autores: Luiselli, L.; Angelici, F.M.; Di Vittorio, M.; Spinnato, A.; Politano, E.
A field survey was conducted in a highly degraded barren environment in Sicily in order to investigate herpetofaunal community composition and structure, habitat use (niche breadth and overlap) and relative abundance of a snake predator and two species of lizard prey. The site was chosen because it has a simple community structure and thus there is potentially less ecological complexity to cloud any patterns observed. We found an unexpectedly high overlap in habitat use between the two closely related lizards that might be explained either by a high competition for space or through predator-mediated co-existence i.e. the prevention of the competitive exclusion of one lizard over the other. We also found a strong positive correlation between predator...

The Common toad Bufo bufo sensu lato is a widespread, morphologically conserved taxon. Recent studies have uncovered deep genetic differentiation between population groups, highlighting the need to revise the current taxonomy of the group and recognize additional species. Here we investigate patterns of variation in molecular (a mitochondrial DNA restriction enzyme assay and sequence data for two nuclear DNA fragments totalling 979 bp) and 17 morphological variables in Northern France where two of these groups meet (B. bufo sensu stricto and B. spinosus), in order to delineate their contact zone and uncover characters that would allow discrimination of the two taxa. Mitochondrial DNA data show an abrupt transition from areas where B. bufo is present to...

Zoogeographic and Taxonomic status of the South American snake Tachymenis surinamensis (Colubridae)
Provedor de dados: 16
Autores: Myers, C.W.
Introduction Tachymenis is a characteristic genus of colubrid snakes inhabiting extreme western South America, from coastal Peru and Chile east to Bolivia (Walker, 1945; Peters &amp; Orejas-Miranda, 1970). An extralimital species in Brazil, Tachymenis brasiliensis Gomes, was referred to its own genus (Gomesophis) by Hoge &amp; Mertens (1959). One additional outlying species, Tachymenis surinamensis, was described from "Surinam" by Dunn in 1922, and, until now, has seemed a zoogeographic anomaly. In the present paper, we suggest that the type specimens of T. surinamensis bear erroneous locality data, and we refer the name to the synonymy of Philodryas elegans (Tschudi, 1845), a species of the coastal deserts of western South America. For lending specimens...

X. NOTES ON THE NEWLY DESCRIBED GENUS  CACOPHRYNE DAVIS Recently Davis (1935) pointed out that the toad known in literature as Bufo borbonicus (Tschudi) or Nectophryne borbonica (Tschudi) does not belong to either of these genera, and that it even does not belong to the Bufonidae, for the species differs from the true toads (Bufonidae) in two important characteristics, as it lacks Bidder's organs and does not possess testes of an elongated shape. Moreover the pectoral girdle proved to be firmisternal instead of arciferal. A new genus, Cacophryne, in the family Atelopodidae, was erected for this species by Davis, and this author (1935, p. 90) mentions that possibly some other species at present included in the genus Bufo, i.e., Bufo penangensis (Stol.),...

INTRODUCTION In a recent paper, Lynch &amp; Freeman (1966) discussed the systematic position of a small hylid frog, Allophryne ruthveni, described in 1926 by Gaige from British Guiana. They tentatively placed it in the family Hylidae, because it shows a better agreement with that family than with any other. The material available to them consisted of six specimens, all from "the foothills of the northeastern face of the Guiana Massif" in Guyana (formerly British Guiana). Since a few years the present author has been engaged in an investigation of the herpetofauna of Surinam (Dutch Guiana). During these studies, a fair number of A. ruthveni specimens was examined.

The snakes of Somaliland and the Sokotra Islands
Provedor de dados: 16
Autores: Parker, H.W.
The systematic status of the snakes recorded from the area has been reinvestigated, often in the light of new material. Allometric growth is shown to occur in several species and taxonomic errors arising from its previous non-recognition are rectified. The same feature is also used to determine the respective ontogenetic levels of closely allied forms. The fauna of the Sokotra group is shown to have greater relationships with the Palaearctic and Oriental regions than with the Ethiopian and to consist of mainly primitive types; they are assumed to have been isolated in the islands since the mid-Miocene. The mainland fauna, though predominantly Ethiopian, contains a strong northern admixture and this element predominates in the northern coastal plain which...

INTRODUCTION During a recent collecting trip, financed by grant W 956-2 from WOTRO (Netherlands Foundation for the Advancement of Tropical Research), I spent 47 days (22 August-7 October 1968) on the Sipaliwini savannah in southern Surinam. The Sipaliwini savannah is part of an extensive savannah that covers the watershed between the Sipaliwini River in Surinam and the Paroe River in Brazil. Though the watershed is very low, the waters of Sipaliwini and Paroe Rivers never seem to make contact, as is the case with other rivers on the Rupununi savannah and in southern French Guiana. About one tenth of this savannah is situated in Surinam, the remainder in Brazil (see inset fig. 3). G. Mann (in Fittkau et al., 1968) calls this a tropical wet savannah and...

Species delineation in Hylarana is complicated due to a lack of distinct colour differences or striking morphological characters, leading to potential misidentification. We conducted extensive surveys throughout the Western Ghats-Sri Lanka biodiversity hotspot and performed multiple gene (16S, COI and Cytb) barcoding using 103 samples collected from cultivated land and natural habitats. Genetic distance comparisons and Neighbor Joining trees indicated the presence of at least 14 candidate species in the region, supported by taxa groupings for all three genetic markers. Utilising a combination of molecular and morphological data, we describe seven...

Preliminary notes on the taxonomy of Tarentola annularis and T. ephippiata (Sauria: Gekkonida)
Provedor de dados: 16
Autores: Grandison, A.G.C.
Among a large collection of West African lizards sent to me for identification early in 1952 by l'lnstitut Français d'Afrique Noire were a number of individuals belonging to the genus Tarentola. The latest taxonomic treatment of Tarentola available at that time was by Loveridge (1947). In his study he had considered Tarentola annularis and T. ephippiata to be geographical races of a single species, the subspecies annularis occurring in Egypt, Sinai, Eritrea, Ethiopia and British Somaliland and the subspecies ephippiata occurring to the west of these areas, in Nigeria, French West Africa, Portuguese Guinea and Gambia. He also synonymised T. senegalensis Boulenger with ephippiata and suggested that T. hoggarensis Werner might be a synonym too. Thus,...

On a new species of Denisonia (Reptilia, Serpentes) from New Guinea
Provedor de dados: 16
Autores: Brongersma, L.D.; Knaap-van Meeuwen, M.S.
Until now the Elapid genus Denisonia had not been recorded from New Guinea, and this is remarkable in so far as the genus is known from Australia (and Tasmania) to the south, and from the Solomon Islands to the northeast of New Guinea. It is therefore not very surprising that now evidence has been procured of the presence of the genus in New Guinea. A single specimen of a species that we believe to be new to science was collected at Merauke in southern West New Guinea by Mr. A. J. M. Monsanto in 1959. The genus Denisonia is here accepted in its old sense, such as it was used by Boulenger (1896, p. 332), and by the majority of subsequent authors. Recently, Worrell (1961a; 1961b, pp. 24-26; 1963) has made attempts to divide Denisonia into eight genera, but...

The Anatomy of Natrix vittata (L.)
Provedor de dados: 16
Autores: Bergman, R.A.M.
MATERIAL AND PROBLEM For the investigation of the anatomical pattern of Natrix vittata, the same material was used as for the description of the life of this snake. A preliminary question was whether both groups from Surabaia and from Tjimahi may be used for statistical treatment as a single unit or if they represent different varieties. The animals are easily recognisable and there is no outward sign which would indicate a difference between the group from the eastern coastal plains and the one from the western hills although the distance between both localities is about 800 km. The range of the body length is for both groups the same, for adult males in Surabaia 341-441 and in Tjimahi 346-457, and for females 392-560 and 395-555. In none of the other...

On the discovery and origin of a Javan population of the Indochinese colubrid snake Dendrelaphis subocularis (Boulenger, 1888): a multivariate study
Provedor de dados: 16
Autores: Rooijen, J. van; Vogel, G.
The colubrid snake Dendrelaphis subocularis is distributed throughout Indochina, the southern limit of its range corresponding with the Isthmus of Kra, an important biogeographic barrier that separates the Indochinese biota from the Sundaic biota. This study presents five museum specimens that represent a hitherto unknown population that inhabits the Sundaic island Java. Thus, the distribution of Dendrelaphis subocularis is disjunct, with the Javan population being isolated by 2000 kilometres from the nearest mainland population. Principal Components Analysis was applied to morphological data taken from the five Javan specimens as well as from 26 museum specimens of Indochinese origin. Regression analysis of the spatial pattern of the resulting scores...

Zoological notes from Port Dickson : I. Amphibians and reptiles

Autores: Brongersma, L.D.
During the time that I was stationed at Port Dickson (State of Negri Sembilan) on the west coast of the Malay Peninsula, a small zoological collection was made. The specimens were brought to me by the personnel of different units of the Royal Netherlands Forces, while I am also indebted to Major C. Rae, RASC, for some interesting specimens. Nearly all specimens belong to common species. However, this area has not been studied so very extensively and therefore, it seems worth while to place these species on record. Unless otherwise stated the specimens are from the strip of country along the coast road to the south of Port Dickson to about ten miles from the township. Where no unit is mentioned, the specimens have been collected by personnel of my own unit...

Contributions to Indo-Australian Herpetology
Provedor de dados: 16
Autores: Brongersma, L.D.
A complete account of all the reptiles then known to occur in the Indo-Australian Archipelago was published by De Rooij in 1915 and 1917. Since this time several new species have been described, while others have been suppressed or revived. Also the problem of geographical variation begins to penetrate in herpetology more and more. While studying the herpetological collections of the Rijksmuseum van Natuurlijke Historie, Leiden and the Zoological Museum, Amsterdam, it became clear to me that, though De Rooij's books offer a sound basis for further studies on the reptiles of the Indo-Australian Archipelago, a great deal of revisional work must still be done before our knowledge of the herpetological fauna of that region will be fairly complete.

Autores: Kluge, A.G.
A review is given of the tortuous history of the name Gonydactylus Kuhl and Van Hasselt, 1822. It is concluded that the name is invalid. Goniodactylus and Gonyodactylus are unjustified emendations. As type-species Cyrtodactylus pulchella Gray, 1827, is selected, making Cyrtodactylus Gray, 1827, a junior objective synonym and protecting Tarentola Gray, 1825. A lectotype for Cyrtodactylus marmorata Gray, 1831, is designated. The nomenclatural consequences of the subgeneric division of Cyrtopodion Fitzinger, 1843, are examined.

Autores: Grandison, A.G.C.
INTRODUCTION In comparing some small Ethiopian Bufo with the descriptions, types and other examples of numerous forms from East and Central African countries I became very much aware of the confusion that exists in the taxonomy and of the need for a revision of this group of dwarf toads. Most of the earless East African toads have received little or no attention since Loveridge's papers in the 1930s and a bewildering assortment of characters of doubtful taxonomic value have been used. Two of the most misleading terms applied to these small toads are "tympanum hidden" and "paratoid obscure". Often preservation alone has rendered the outline of the tympanic annulus and the paratoid obscure or invisible and only dissection reveals the true extent of the...

Functional morphology of a highly specialised pivot joint in the cranio-cervical complex of the minute lizard Ablepharus kitaibelii in relation to feeding ecology and behaviour
Provedor de dados: 16
Autores: Natchev, N.; Tzankov, N.; Vergilov, V.; Kummer, S.; Handschuh, S.
The snake-eyed skink Ablepharus kitaibelii is one of the smallest European lizards, but despite its minute size it is able to feed on comparatively large prey. Here we investigate the diet of A. kitaibelii and the mechanisms that allow the skink to overpower relatively large and even noxious prey. High-speed cinematography showed that A. kitaibelii uses a series of shaking and battering movements to immobilise and kill prey prior to swallowing. During this process, the skinks rises up on the hind limbs and then whacks the prey sidewise on the substrate by twisting the trunk, neck and head laterally. Our analysis showed that the shaking kinematics is very uniform among the investigated specimens. The morphological investigation of the cranio-cervical system...

Early ontogeny shows the same interspecific variation as natural history parameters in the crested newt (Triturus cristatus superspecies) (Caudata, Salamandridae)
Provedor de dados: 16
Autores: Cvijanović, M.; Ivanović, A.; Kolarov, N.T.; Džukić, G.; Kalezić, M.L.
When the phenotypic divergence within a monophyletic group is characterised by parallel variation of different phenotypic traits, it is very likely that the environment through constraints and/or selection has affected the developmental pathways simultaneously. Such patterns of phenotypic divergence characterise the phenotypic evolution of the crested newts (Triturus cristatus superspecies). In this study, we have examined interspecific variations in the embryonic development of four crested newt species. The species are similar with respect to some basic developmental traits, some morphologically defined developmental stages and the survival rate during early embryogenesis. However, there is significant variation in the developmental rate, as well as...

Autores: Veldmeijer, A.J.
A new species of pterosaur, Coloborhynchus spielbergi sp. nov. (Pterodactyloidea), from the Romualdo Member (Albian) of the Santana Formation is described. The type consists of the skull, mandible and many of the post-cranial bones. The specimen displays a high degree of co-ossification indicating that the animal was an adult and likely quite old when it died. The wingspan is reconstructed at nearly 6 m. Among the characteristic features are a large anteriorly positioned premaxillary sagittal crest and a smaller, also anteriorly positioned dentary sagittal crest, a flat anterior aspect of the skull from which two teeth project and a ventrally fused pelvis. Comments on Brazilian pterosaurs are made in connection with the classificiation of the Leiden...

An attempt to prepare a survey of the poisonous snakes of Surinam led to the discovery of a specimen of the very rare coral snake Leptomicrurus collaris (Schlegel) in the Zoological Museum, Amsterdam, and to tracing another specimen in the Staatliche Museum für Naturkunde, Ludwigsburg (Stuttgart Museum). For long years the species was known under the name of Hemibungarus collaris (Schlegel), and as such it was supposed to occur in the Philippine Islands. The history of Elaps collaris Schlegel, 1837, was briefly discussed by Schmidt (1937), who transferred the species (together with Elaps narduccii Jan, 1863) to a separate genus Leptomicrurus Schmidt, 1937.

Natural history and distribution of Agalychnis craspedopus (Funkhouser, 1957) (Amphibia: Anura: Hylidae)
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Cadle, J.E.
Aspects of reproductive behaviour, calls, clutch sizes, and larval morphology are described for Agalychnis craspedopus (Funkhouser, 1957). New distributional records extend the range of this species to southern Amazonian Peru. In most respects reproductive behaviour of A. craspedopus is similar to that of other phyllomedusine frogs. In southern Peru clutches were suspended above water-filled hollow cavities in logs, but in Ecuador tadpoles were found in a pool on the ground with no directlyoverhanging vegetation. Agalychnis craspedopus lays small clutches (mean = 17 eggs) with large eggs. Breeding possibly takes place throughout some years in southern Peru, but this undoubtedly varies depending on rainfall. Some aspects of reproductive biology, and tadpole...

In 1973 the Convention in International Trade in Endangered Species of Wild Fauna and Flora (CITES) was called to life as to regulate the international wildlife trade, and to prevent species becoming (economically and biologically) extinct. The trade in freshwater turtles and tortoises in Asia is so huge that it threatens the survival of many species. In 2006 and 2007, during three surveys at Chatuchak market in Bangkok, Thailand, we recorded a significant trade in non-native CITES-listed freshwater turtles and tortoises to be used as pets. We documented a total of 688 individuals of 19 species from different regions of the world, many of which are globally threatened with extinction.

Newts of the genus Triturus (Amphibia, Caudata, Salamandridae) are distributed across Europe and adjacent Asia. In spite of its prominence as a model system for evolutionary research, the phylogeny of Triturus has remained incompletely solved. Our aim was to rectify this situation, to which we employed nuclear encoded proteins (40 loci) and mitochondrial DNA-sequence data (mtDNA, 642 bp of the ND4 gene). We sampled up to four populations per species covering large parts of their ranges. Allozyme and mtDNA data were analyzed separately with parsimony, distance, likelihood and Bayesian methods of phylogenetic inference. Existing knowledge on taxonomic relationships was confirmed, including the monophyly of the genus and the groups of crested newts (four...

A look at the key to the species of the genus Lepidodactylus in Boulenger's Catalogue of Lizards (I, 1885, p. 162) shows at once that the species are placed in two groups differing in the development of the inner digit. This was first noticed by STEJNEGER (1899, p. 800) who transferred L. crepuscularis (Bav.), L. ceylonensis Blgr. and L. aurantiacus (Bedd.) to the genus Hemiphyllodactylus Blkr. At the same time he described a new species, H. leucostictus, from the Hawaii Islands. The different authors on Asiatic herpetology did not notice this publication as it chiefly dealt with the land-reptiles of the Sandwich-Islands.

INTRODUCTION The first scientific description of the Komodo Dragon (Varanus komodoensis), given by P. A. Ouwens, appeared only as late as 1912. During some time following this event, but little information on the species became available and no specimens were captured. Only in 1926, an American expedition to the island of Komodo, led by W. D. Burden, for the first time succeeded in capturing alive two Komodo Dragons and in transporting these to the U.S.A. Both animals were received at the New York zoological garden on 11 September 1926. One of the specimens, a male, died on 24 November 1926; the other, of unknown sex, died on 19 October 1926 (Jones, 1965: 92). On 14 October 1926, a male Komodo Dragon was received at the Amsterdam zoological garden. It was...

Observations on eggs of eublepharid lizards, with comments on the evolution of the Gekkonoidea
Provedor de dados: 16
Autores: Werner, Y.L.
Captive specimens of Coleonyx v. variegatus, C. v. bogerti, Eublepharis macularius and Hemitheconyx caudicinctus laid parchment-shelled, moisture dependent eggs, resembling those of diplodactyline geckos and most lepidosaurians. Eublepharid eggs, including those of Aeluroscalabotes measured in radiographs, are twice as long as broad. Supporting and complementary evidence in the literature is considered. It is concluded that the Eublepharidae are a monophyletic group of the Gekkonoidea, retaining the primitive egg type. Functional and evolutionary aspects of various characteristics of different gekkonoid eggs are discussed, and conclusions drawn.

Provedor de dados: 16
Autores: Rocha, S.; Ineich, I.; Harris, D. James.
With an impressively wide distribution, Gehyra mutilata is present on almost all Indian and Pacific Ocean islands and in large regions of Southeast Asia and Indonesia. Mitochondrial sequence data (~500 bp) from individuals covering large parts of its (mainly insular) distribution reveals deep cryptic variation and strong geographic structure, with two well differentiated lineages. Molecular data also reveals that the wide Indian and Pacific insular distribution of Gehyra is very recent and, at least across the Indian Ocean islands, most probably the result of human-aided dispersal, as no variation within this lineage was found. Further research is needed to determine geographic patterns of variation across Southeast Asia, the level of genetic variation,...

The wormsnakes (family Typhlopidae) of the Neotropics, exclusive of the Antilles
Provedor de dados: 16
Autores: Dixon, J.R.; Hendricks, F.S.
The systematic arrangement of the worm snakes (Typhlops) from the continental western hemisphere is presented. Allocations of many names historically assigned to Central and South American Typhlops are clarified. The continental Typhlops include nine species, two of which are described as new. The intraspecific variation of all species is explored within the limitations of known specimens. Three major radiations of New World Typhlops are postulated to account for the radiations of the present species groups.

Some notes on species of the genera Bachia and Scolecosaurus
Provedor de dados: 16
Autores: Brongersma, L.D.
Our herpetological collections contain only five specimens referable to the genera Bachia and Scolecosaurus, while the genus Bachia is represented in the Amsterdam Zoological Museum by eight specimens. Scanty though this material may be, some of the specimens proved to be of sufficient interest to justify the publication of these notes. At present thirteen species of Bachia 1) are known, viz., the twelve species listed in a key by Burt &amp; Burt (1931, pp. 315-316) and Bachia anomala Roux (1929, p. 31). Perhaps Apatelus bresslaui Amaral (1935) must be referred to Bachia too. Roux (1929), Burt &amp; Burt (1931) and Loveridge (1933) published notes on the variation of several characters, and these authors showed that the variation is greater than had been...

Herpetological Notes XIV - XVI
Provedor de dados: 16
Autores: Brongersma, L.D.
At the request of Dr K. P. Schmidt, Chicago, I recently examined the types of Psammophis antillensis Schl. This species as originally described was a composite, and it is, therefore, necessary to select a lectotype to restrict the name antillensis to one of the species involved. The difficulty is that Schlegel did not label his types as such, and that in most cases he did not mention how many specimens he actually examined. From the introduction to his Essai we know that Schlegel visited Paris, that the collections of the Museum National d'Histoire Naturelle were placed at his disposal, and that he was allowed to take the undescribed species with him to Leiden for further studies (Schlegel, 1837, I, p. XXIV). What happened in the case of Psammophis...

Rediscovery of a forgotten snake in an unexpected place and remarks on a small herpetological collection from southeastern Brazil
Provedor de dados: 16
Autores: Hoogmoed, M.S.
A collection of snakes and frogs collected in the area of Porto Real, Rio de Janeiro State, Brazil, was bought in December 1890 and remained unidentified until now. The collection comprises 100 snakes belonging to 18 species and 152 frogs belonging to 19 species. A comparison with the herpetofauna from nearby Serra do Japi in São Paulo is made. General remarks on variation and identification are made for a number of species. Among the snakes were two specimens of Cercophis aurata (Schlegel, 1837), a species described on the basis of one specimen from Suriname, and no new specimens having been recorded until now. The new individuals cause the known area of distribution to be greatly enlarged, but such a large distribution area occurs in several other snakes...

Notes on the herpetofauna of Surinam : VI. Resurrection of Hyla ornatissima Noble (Amphibia, Hylidae) and remarks on related species of green tree frogs from the Guiana area
Provedor de dados: 16
Autores: Hoogmoed, M.S.
In the present paper Hyla ornatissima Noble is removed from the synonymy of Hyla granosa Boulenger, and resurrected as a separate species on the basis of morphological, ecological and acoustical differences. Another relative of this group occurring in Guiana is Hyla sibleszi Rivero. Because of its superficial resemblance with these frogs Hyla punctata (Schneider), of another species-group, is also treated. All four species are extensively described, data on life history and distribution are given. H. sibleszi, so far only known from the type material and some associated specimens, is reported from several new localities in Venezuela and Guyana. It is suggested that the function of the intricate dorsal pattern of H. ornatissima serves to protect the animal...

The gut contents of five juvenile individuals of the loggerhead turtle Caretta caretta (L.) from waters around Madeira, Selvagem Grande (Selvagens Islands) and São Miguel (Azores) were analysed macro- and microscopically. Macroscopic investigations showed that epipelagic salps (e.g., Pyrosoma atlanticum Péron) and gastropods (e.g., Ianthina spp. and Pterotrachea spp.) constituted an important part of the food remains present in these loggerheads. To a lesser extent this also holds for organisms such as goose-barnacles (Lepas spp.). and Idotea metallica Bosc, which live on drifting materials, including algae. Microscopic examination revealed the presence in all turtles of large numbers of nematocysts, deriving mainly from Siphonophora and to a lesser extent...

On the Presence or Absence of Hypapophyses under the posterior precaudal Vertebrae in some Snakes
Provedor de dados: 16
Autores: Brongersma, L.D.
In his "Catalogue of Snakes" Boulenger (1893—1896) followed Cope in considering the presence or absence of well developed hypapophyses under the posterior precaudal vertebrae as a character of great systematic importance. Thus Boulenger divided the genera of both the Colubrinae and Dipsadomorphinae (= Boiginae) into two groups; one of these groups is characterized by the presence of well developed hypapophyses under the posterior precaudal vertebrae, while in the genera of the other group these hypapophyses are lacking. Rosén (1905a) showed that this character was not so important as previous authors had believed it to be, for he found well developed hypapophyses1) in Chrysopelea ornata (Shaw) and Anisodon lilljeborgi Rosén (= Psammodynastes pulverulentus...

Autores: Avila-Pires, T.C.S.
Eighty-nine species of lizards, six of which polytypic (forming a total of 97 taxa), are presently known from Brazilian Amazonia. This number includes six species and one subspecies described as new to science in this paper: Stenocercus fimbriatus, Lepidoblepharis hoogmoedi, Leposoma osvaldoi, L. snethlageae, Tretioscincus oriximinensis, Tupinambis longilineus, and Anolis nitens tandai. Stenocercus dumerilii is resurrected from the synonymy of S. tricristatus. Bachia cophias is considered a junior synonym of B. flavescens. B. peruana is a new record from Brazil. Anolis nitens has priority over A. chrysolepis. The Amazonian Tupinambis is shown to be T. teguixin (of which T. nigropunctatus is a junior synonym). The name T. merianae should be used for T....

Kugelzellen in larval anuran epidermis: an ultrastructural study on tadpoles of Pelobates cultripes (Pelobatidae) and Phyllobates bicolor (Dendrobatidae)
Provedor de dados: 16
Autores: Delfino, G.; Quagliata, S.; Giachi, F.; Malentacchi, C.
Prior to hind limb development, tadpoles of the western spadefoot frog Pelobates cultripes (Pelobatidae) and dart-arrow frog Phyllobates bicolor (Dendrobatidae) possess large clear cells in the basal layer of the epidermis. These cells closely resemble Kugelzellen (KZn) of larval clawed frog, Xenopus laevis (Pipidae) and share ultrastructural traits with Leydig cells (LCs) of Caudata and Caecilia. In both species, KZn possess a transparent cytoplasm and a remarkable peripheral cytoskeleton of tonofi laments: in the arrow frog tonofi laments form bands parallel to the cell surface, in the spadefoot frog thin bundles, arranged in a three-dimensional network. KZn combine turgor (resulting from the hydrated cytoplasm) with stiffness (from peripheral...

Checklist of the Savanna inhabiting frogs of the El Manteco region with notes on their Ecology and the description of a new species of Treefrog (Hylidae, Anura)
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Gorzula, S.J.
Three years of fieldwork in the El Manteco region by the junior author formed the basis for the checklist presented here. Among the frogs assembled is a small species of Ololygon, new to science, also found in Guyana and Surinam. The anuran succession in the temporary lagoons, formed during the rainy season, was studied during three years and a consistent pattern was found. Comparisons with the llanos fauna are made and it is concluded that the El Manteco region contains a relatively large percentage of Amazonian elements, absent from the llanos.

Additional results and discussion to the paper: Asymmetric viability of reciprocal-cross hybrids between crested and marbled newts (Triturus cristatus and T. marmoratus)
Provedor de dados: 16
Autores: Arntzen, J.W.; Jehle, R.; Bardakci, F.; Burke, T.; Wallis, G.P.
Hybridization between divergent lineages often results in reduced hybrid viability. Here we report findings from a series of independent molecular analyses over several seasons on four life stages of F1 hybrids between the newts Triturus cristatus and T. marmoratus. These two species form a bimodal hybrid zone of broad overlap in France, with F1 hybrids making up about 4% of the adult population. We demonstrate strong asymmetry in the direction of the cross, with one class (cristatus-mothered) making up about 90% of F1 hybrids. By analyzing embryos and hatchlings, we show that this asymmetry is not due to prezygotic effects, as both classes of hybrid embryos are present at similar frequencies, implicating differential selection on the two hybrid classes...

On the distribution of Bidder's organ in Bufonids
Provedor de dados: 16
Autores: Dubois, R.
It is a well-known fact that Bidder's organ is an undeveloped ovary. It is found in all adult male and in many adult female as well as in all juvenile male and female specimens of Bufo-species, and it is situated between the fatbody and the gonad. The fact that Bidder's organ is a potential ovary is not only derived from its morphology, but has also been proved experimentally by Harms (1923) and Ponse (1924), for after castration of male toads and after ovariectomy of female common toads (Bufo vulgaris Laur. (= B. bufo (L.)) Bidder's organ may develop into a normally functioning ovary. In 1931 Stohler compiled our knowledge concerning the distribution of Bidder's organ in the Bufonidae; in addition the occurrence of the organ was described in several other...

This study of Chthonerpeton indistinctum (Reinhardt &amp; Lütken, 1861) considers 25 morphometric characters, teeth-counts and sex, based on 96 specimens. A multivariate analysis of characters and comparisons of geographically arranged samples is carried out by graphic and statistical methods. No trends in geographical variation were found. Subsequently a redescription of the species is presented, including measurements and counts. Sexual dimorphism was observed for four characters related to the cloacal region. The results are discussed and compared with previous reports. Character-variation is also studied. Primary annuli counts show very low variation; sample variation profiles were similar for the remaining characters. A revision of biological data...

I. Lygosoma nieuwenhuisii VAN LIDTH DE JEUDE. Mertens (1929, p. 215, note) mentioned already that the young Lygosoma from Sandakan Bay, North Borneo, which had been referred to L. smaragdinum Less. by Van Lidth de Jeude (1893, p. 252) did not belong to that species but that it was related to L. nieuwenhuisii Lidth (1905, p. 195). Comparison of this young specimen with the type of L. nieuwenhuisii proved that it belonged to this species. The description of the type must however be corrected in some minor points. This single type-specimen was collected during the Dutch Scientific Expedition in Central-Borneo 1894 ('sRijks Museum van Natuurlijke Historie, Herpet. n° 4455).

Activity of the body wall musculature of the African Clawed Toad, Xenopus laevis (Daudin), during diving and respiration
Provedor de dados: 16
Autores: Jongh, H.J. de.
INTRODUCTION Mechanisms for regulating the specific weight of the body are well known in fishes. In other aquatic vertebrates the lungs might have a function similar to that of the swimbladder or the lungs in fishes. In anuran tadpoles the lungs may serve as hydrostatic balancers, but this has not been verified experimentally. Active regulation of lung volume, and thus of body volume and specific weight, during diving is unknown in adult anurans, although Parker (1936) expressed the opinion that in male Trichobatrachus robustus the lungs, which possess a posterior diverticulum surrounded by specialized musculature, serve as a hydrostatic apparatus. If there is no active regulation of lung volume during diving, the volume of the lungs will depend on such...

Hyla inermis (Peters), a species hitherto erroneously referred to the Leptodactylid genus Cyclorana (Anura, Hylidae/Leptodactylidae)
Provedor de dados: 16
Autores: Straughan, I.R.
INTRODUCTION Extensive collections of frogs from Queensland (reported in detail, Straughan, 1966) failed to include the species Cyclorana inermis (Peters), although Slevin (1955) recorded it as abundant in central Queensland. However a widely ranging species of ground Hyla (undescribed in that genus) occurred frequently in collections from central and northern Queensland. In all external features this species fitted the description of Cyclorana inermis given by Parker (1940: 17). In the present paper Peters' syntype of C. inermis (reg. no. RMNH 1888) in the Rijksmuseum van Natuurlijke Historie, Leiden, is examined, and compared with the apparently new species of Hyla.

We performed an exploratory analysis of the morphology of the cranium in the white olm (Proteus anguinus anguinus) and the black olm (P. a. parkelj) with micro-CT scanning and geometric morphometrics. The mudpuppy (Necturus maculosus) was used as an outgroup. The black olm falls outside the white olm morphospace by a markedly wider skull, shorter vomers which are positioned further apart and by laterally positioned squamosals and quadrates relative to the palate (the shape of the buccal cavity). On account of its robust skull with more developed premaxillae a shorter otico-occipital region, the black olm is positioned closer to Necturus than are the studied specimens of the white olm.

Correlates between morphology, diet and foraging mode in the Ladder Snake Rhinechis scalaris (Schinz, 1822)
Provedor de dados: 16
Autores: Pleguezuelos, J.M.; Fernández-Cardenete, J.R.; Honrubia, S.; Feriche, M.; Villafranca, C.
In many vertebrates, foraging mode (active versus sit-and-wait) is tied to some traits of their natural history such as morphology, type of prey, rate of food acquisition, and survival rate. We explore the correlates between some morphological traits of a Mediterranean colubrid and its feeding ecology and the predation risk, by comparing data on teeth number, tail damage, and diet. A large sample (n = 368) of the Ladder Snake, Rhinechis scalaris is used. The species feeds almost exclusively on endotherms, mainly mammals (nearly 95% of the diet in mass), which set R. scalaris among the most stenophagous snakes in the western Palaearctic. There is also a high percentage of motionless prey in the diet (up to 50% in prey mass), such as nestling birds, mammals...

The pattern of dermal-vertebral correlation in snakes and amphisbaenians
Provedor de dados: 16
Autores: Alexander, A.A.; Gans, C.
INTRODUCTION It has long been known that the arrangement of external scales retains a constant relation to the primary pattern of mesodermal segmentation. The ratio of the number of dermal scale rows or annuli to the number of vertebrae has, therefore, been considered to be of fundamental importance in squamate classification (Stehli, 1910; Camp, 1923). Yet the difficulty of determining it has fostered the presentation of hypotheses based on relatively few total counts; some such hypotheses have relied upon comparisons made by dissection along limited portions of the trunk. The general implication communicated by the many statements in the literature has been that the ratios are constant at the generic or familial level, that the ratios ordinarily...

The RMNH possesses a stuffed specimen, of which the left forelimb has been amputated in life and of which the skull is no longer present in the specimen. The Paris museum possesses a skull that fits the Leiden specimen. Thus, the stuffed specimen and the skull together form the complete holotype, each object can be considered a “schizotype” of the holotype.

On the Arrangement of the scales on the dorsal surface of the digits in Lygosoma and allied genera
Provedor de dados: 16
Autores: Brongersma, L.D.
Smith (1937, pp. 215—216, fig. 1) described and figured the different types of scales of the lower surface of the toes in Lygosoma and allied genera. Although several of these types may be found within one genus, they are useful as additional characters to distinguish certain species or groups of species from each other. When studying a number of IndoAustralian scincid lizards, I noticed that the arrangement of the scales on the dorsal surface of the digits shows differences too, which it may be worth while to include in the descriptions of the species as they provide additional characters. The arrangement of the scales seems to be fairly constant within the species. In some cases slight variations were found, but in a series of over one hundred specimens...

On an Alopoglossus from Surinam
Provedor de dados: 16
Autores: Brongersma, L.D.
Rijksmuseum van Natuurlijke Historie, Leiden With one textfigure A single Alopoglossus was taken by Dr. K. M. Hulk during the Corantine Expedition in Surinam. It is described in the present paper as a distinct subspecies of Alopoglossus copii Blgr. Peracca (1894, p. 3) showed that in the type of Pantodactylus borellii (= P. schreibersii (Wiegm.)) the tongue is partly covered by imbricate papillae and partly by oblique plicae. He further mentions (1. c., p. 4) that his observation was confirmed by Boulenger who found too that in Pantodactylus schreibersii (Wiegm.) the posterior half of the tongue may be covered with oblique plicae, while the anterior half bears imbricate papillae. Therefore, Burt &amp; Burt (1931, p. 357) unite the genera Alopoglossus Blgr....

Vertebral number is highly evolvable in salamanders and newts (family Salamandridae) and variably associated with climatic parameters
Provedor de dados: 16
Autores: Arntzen, J.W.; Beukema, W.; Galis, F.; Ivanović, A.
In vertebrates, the relative proportion of the number of trunk and caudal vertebrae is an important determinant of body shape. While among amphibians frogs and toads show low variation in vertebrae numbers, in salamanders the numbers of trunk and caudal vertebrae vary widely, giving rise to phenotypes in the range from short-bodied and long-tailed to long-bodied and short-tailed. We analysed vertebral numbers in the family Salamandridae in a phylogenetic context and calculated the relationship between vertebral changes and changes in climate and other environmental parameters. A significant association was found between morphological change with precipitation and temperature. However, annual precipitation affected the two main groups of salamandrid...

The early specimens of the potto Perodicticus potto (Statius Müller, 1776) in the National Museum of Natural History, Leiden, with the selection of a neotype
Provedor de dados: 16
Autores: Smeenk, C.; Godfrey, L.R.; Williams, F.L.
The potto was first recorded and figured by Willem Bosman in 1704. The name Lemur potto Statius Müller, 1776 is exclusively based upon Bosman’s account and figure, which are reproduced in full. The type locality is Elmina on the Gold Coast, the present Ghana. No type specimen was collected. The early pottos in the Leiden Museum are listed and their history is given, with special reference to the animals obtained by H.S. Pel. The publications on this material are reviewed. An adult female, RMNH 39375: mounted skin and skeleton acquired by Pel in 1849 at Dabocrom (Dabo Krom) near Sekondi, coastal Ghana, is designated the neotype of Lemur potto Statius Müller, 1776. The neotype is extensively described and figured. Taxonomic notes on the putative (sub)species...

Molecular phylogeny, morphology and bioacoustics reveal five additional species of arboreal microhylid frogs of the genus Anodonthyla from Madagascar
Provedor de dados: 16
Autores: Vences, M.; Glaw, F.; Köhler, J.; Wollenberg, K.C.
We provide a partial revision of the microhylid frogs of the genus Anodonthyla, endemic to Madagascar, based on comprehensive molecular, bioacoustic and morphological data sets that include newly collected specimens from multiple localities. The molecular trees provide strong evidence for the polyphyly of several nominal species as they were previously defined, especially of Anodonthyla boulengeri and A. nigrigularis. As a consequence, we here resurrect the nomen Mantella pollicaris Boettger as Anodonthyla pollicaris from the synonymy of A. boulengeri, and we describe four new species, all with strong genetic divergences to other nominal species: Anodonthyla emilei from Ranomafana National Park, a comparatively medium- sized species characterized by a...

Note on Celestus de la sagra (Cocteau)
Provedor de dados: 16
Autores: Brongersma, L.D.
In his key to the species of the genus Diploglossus, Boulenger (1885, p. 284) distinguishes between two groups of species, viz., one group in which the digits terminate in "a large compressed sheath, into which the claw may be entirely or nearly entirely retracted", while in the other group such a sheath is absent. Barbour (1910, p. 297) considers the presence or absence of an ungual sheath as a character of generic value ; he separates the species lacking such a sheath from the true Diploglossus, and revives the genus Celestus Gray for them 1). Burt &amp; Burt (1931, pp. 241-242) also stress the importance of this character. Indeed the sheath is absent in Celestes occiduus (Shaw), of which Celestus striatus Gray (the type of the genus) is a synonym. Of...

Revisionary notes on the Sphenomorphus isolepis complex (Lacertilia, Scincidae)
Provedor de dados: 16
Autores: Storr, G.M.
Taxa that have only just attained specific distinction from each other can be of great interest to students of evolution, though their classification may pose serious problems for taxonomists. For example, the sparrows Passer domesticus and P. hispaniolensis behave as good species in most parts of their shared range but hybridize in other parts. The gulls of the Larus argentatus complex form a ring of annectant races around the Holarctic, but their overlapping terminal segments behave as good species in western Europe. Each of these phenomena (described by Mayr, 1963) is paralleled in Australian skinks of the genus Sphenomorphus, the first in the richardsonii complex and the second in the isolepis complex. Previous analyses of these complexes (Storr, 1967)...

The Life of Natrix vittata (L.)

Autores: Bergman, R.A.M.
GENERAL CHARACTER Natrix vittata, the striped swimmer, is a harmless little snake, about half a meter long and as thin as a little finger, living in Java on coastal plains and in the hills up to 1200 m above see level. In a given area she will be very common but in adjacent regions, which to us may present exactly the same character of humidity, altitude, temperature, vegetation, etc., there will be only very occasionally a Natrix vittata among the catch (de Haas, 1941a). Even in the field she is easily recognisable, as she will lift her head high enough to show the curious design of her ventral shields. If there is an opportunity for examining the snake more closely, the twin small white spots on the head shields will identify her. The colour of the body...

Low genetic variability in the endangered Colombian endemic freshwater turtle Podocnemis lewyana (Testudines, Podocnemididae)
Provedor de dados: 16
Autores: Vargas-Ramírez, M.; Chiari, Y.; Castaño-Mora, O.V.; Menken, S.B.J.
The Magdalena River Turtle (Podocnemis lewyana) is a Colombian endemic species, endangered due to human exploitation and habitat destruction. To date, this species is poorly known ecologically and data on its genetic diversity are lacking. Here we report on the first genetic survey of the species across its distribution range. We obtained mitochondrial DNA sequences (488 bp) of the cytochrome b gene from 109 individuals. Samples belong to populations located at several different localities, grouped in five regions, along the four main river basins: Magdalena, Cauca, San Jorge, and Sinú drainages. We found two haplotypes, which differ in only one nucleotide substitution and which are represented with different frequencies in the five geographic regions....

Patterns of phenotypic variation reveal substantial differentiation in sexual dimorphism of three Psammodromus (Squamata, Lacertidae) species
Provedor de dados: 16
Autores: San-Jose, L.M.; Gonzalez-Jimena, V.; Fitze, P.S.
The Spanish sand racer (Psammodromus hispanicus) has been recently split into three distinct species: P. hispanicus, P. edwardsianus, and P. occidentalis. Some morphological differences have been reported but there is as yet no description allowing unambiguous identification of the three species. Here, we describe differentiation in body measurements, scalation traits, and colour traits as well as in the degree of sexual dimorphism. Our results show that P. edwardsianus can be easily distinguished by the presence of a supralabial scale below the subocular scale, which is absent in the other two species. Psammodromus hispanicus and P. occidentalis can be distinguished by the number of femoral pores, throat scales and ocelli, and the relative width of the...

A large phylogeny of turtles (Testudines) using molecular data

Autores: Guillon, J.-M.; Guéry, L.; Hulin, V.; Girondot, M.
Turtles (Testudines) form a monophyletic group with a highly distinctive body plan. The taxonomy and phylogeny of turtles are still under discussion, at least for some clades. Whereas in most previous studies, only a few species or genera were considered, we here use an extensive compilation of DNA sequences from nuclear and mitochondrial genes for more than two thirds of the total number of turtle species to infer a large phylogeny for this taxon. Our results enable us to discuss previous hypotheses on species phylogeny or taxonomy. We are thus able to discriminate between competing hypotheses and to suggest taxonomical modifications. Finally, we pinpoint the remaining ambiguities for this phylogeny and the species for which new sequences should be...

The choice of external morphological characters and developmental stages for tadpole-based anuran taxonomy: a case study in Rana (Sylvirana) nigrovittata (Blyth, 1855) (Amphibia, Anura, Ranidae)
Provedor de dados: 16
Autores: Grosjean, S.
The morphology of tadpoles has long received too little attention in taxonomic and phylogenetic contexts, beyond the use of Orton’s general tadpole types, despite the potential of larval characters for resolving problems in systematics. A possible explanation for this neglect is the ontogenetic variation of external morphology. In order to understand the value of larval characters in taxonomy and systematics, it is necessary to determine the developmental stage at which characters reach their definitive size, form and colour before meaningful comparisons can be made within and between species. Here I use the tadpole of Rana (Sylvirana) nigrovittata as a model organism to assess ontogenetic character variation. Morphometric measurements were taken, and...

A reevaluation of the evidence supporting an unorthodox hypothesis on the origin of extant amphibians
Provedor de dados: 16
Autores: Marjanovic, D.; Laurin, M.
The origin of frogs, salamanders and caecilians is controversial. McGowan published an original hypothesis on lissamphibian origins in 2002 (McGowan, 2002, Zoological Journal of the Linnean Society, 135: 1-32), stating that Gymnophiona was nested inside the 'microsaurian' lepospondyls, this clade was the sister-group of a caudate-salientian-albanerpetontid clade, and both were nested inside the dissorophoid temnospondyls. We have investigated McGowan's data matrix and isagree with the scoring of 35% of the cells. All taxa and all but two characters are affected. In some cases, we have a different interpretation about correspondence between morphology and character states, or we delimit states differently (or use information that was unknown in 2002). In...

In this paper we list seven species of caecilians known to occur in Surinam. An eighth species, the aquatic Typhlonectes compressicaudus, is likely to be found in Surinam, but there are no voucher specimens. We report the rediscovery of the rare Rhinatrema bivittatum, now known from four specimens, one each from Brazil, French Guiana, Guyana, and Surinam. Microcaecilia taylori, described as a new species from Sipaliwini, is characterized mainly by a complete lack of secondary annuli, a feature which necessitated rediagnosis of the genus Microcaecilia. A Microcaecilia from the Lely Mountains differs from all known specimens of the genus by its larger size.

Since a few years the present author has been engaged in a study of the herpetofauna of Surinam, which resulted in a few publications (Hoogmoed 1967, 1969a, b). In early 1968, a grant was obtained from WOTRO (Netherlands Foundation for the Advancement of Tropical Research, grant W956-2) which enabled me to undertake a seven months collecting trip in Surinam. From the start the purpose was to obtain specimens from several localities in the interior, as the coastal area was thought to be fairly well explored. Moreover, other important goals were to obtain information on the ecology and colours of the living animals and, in the case of the frogs and toads, to make sound records. As a well developed road system in Surinam only exists near the coast and between...

Two localities at heights of 30 and 35 m could be studied, whereas data on a third site were obtained through information from other participants. The herpetological results of the research in the canopy were meagre. Only the frog Hyla leucophyllata (Beireis) and the lizard Mabuya bistriata (Spix) were observed in the canopy. Additionally the terrestrial herpetofauna was studied extensively and turned out to contain some species that had not been reported before from French Guiana. Also, for many species new distribution data within French Guiana were obtained. Le Mission Radeau...

INTRODUCTION Crinia darlingtoni Loveridge, 1933, was described from a series of four specimens collected by P. J. Darlington at the Queensland National Park, Macpherson Range, Queensland, and distinguished by the rudimentary condition of the first finger and the extremely small first toe. Loveridge noted that some specimens bore a resemblance to C. acutirostris Andersson in colouration but did not discuss the phylogenetic relationships of his new species. For a generic revision Parker (1940) examined a juvenile paratype and on the basis of a similarity in the condition of the prevomer, he associated C. darlingtoni with C. leai Fletcher, C. rosea Harrison and C. laevis (Günther). In the last species he also recognized two sub-species, C. l. laevis and C. l....

In literature only very scanty information is to be found about the viscera of the Boid genera Tropidophis and Trachyboa, and therefore I believed it worth while to publish some notes which I made during dissections of the following species and subspecies: Tropidophis melanurus (Schleg.), Tropidophis maculatus haetianus (Cope), Tropidophis pardalis pardalis (Gundl.) and Trachyboa gularis Ptrs. The notes are in no way exhaustive; the specimens have been preserved in alcohol for a long time, and therefore it was not possible to study all features in detail. All but two genera of the Boidae have two well developed lungs. One of these two exceptions was mentioned already by Cope (1894, pp. 218, 220: Ungualia; 1900, p. 697), viz., the genus Ungalia (i.e.,...

The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

Development, comparative morphology and cornification of reptilian claws in relation to claws evolution in tetrapods
Provedor de dados: 16
Autores: Alibardi, L.
The development of claws in different reptiles and their cornification are analyzed using histological, ultrastructural and autoradiographic methods. Claws develop at the tip of digits in relation to the growth of the terminal phalanx and appear as modified scales. The apical epidermis of digit becomes thickened and is associated with a mesenchymal condensation or a dense mesenchyme. The dorsal side of the digit becomes the unguis while the ventral side becomes the sub-unguis. The corneous layer in the unguis is thicker than in the sub-unguis and accumulates hard-keratin while corneocytes remain separated or partially fused. Bundles of hard-keratin tend to accumulate in parallel orientation with respect to the surface and are directed toward the claw tip....

Observations on the vertebral hypapophyses and associated Musculature in some snakes, with special reference to the Colubridae
Provedor de dados: 16
Autores: Malnate, E.V.
Hypapophyses are reported to be present on the anterior precaudal vertebrae of representatives of all snake families, except the Typhlopidae, Leptotyphlopidae, and Uropeltidae. The processes occur on all precaudal vertebrae in the Acrochordidae, Colubridae (auct.), Elapidae, Viperidae, and two subfamilies of the Boidae, the Bolyerinae and Tropidophinae. Among the numerous genera of the Colubridae caudal extent of the presence of the hypapophyses is variable, even within a genus or species. Cope (1864) associated hypapophyses on the posterior precaudal vertebrae with the Homalopsinae. In the years following he utilized the character to distinguish the Homalopsinae (1886), the Colubrinae (1887), the Natricidae (1893); in his last classification (1900), Cope...

Notes on the herpetofauna of Surinam : VII. Revision of the genus Atracus in Surinam, with the resurrection of two species (Colubridae, Reptilia)
Provedor de dados: 16
Autores: Hoogmoed, M.S.
A re-examination of old specimens of the genus Atractus, preserved in the Rijksmuseum van Natuurlijke Historie resulted in the discovery of syntypes of Brachyorrhos badius F. Boie, B. flammigerus F. Boie, B. schach F. Boie and Rabdosoma torquatus Dumeril, Bibron &amp; Dumeril. Lectotypes for all these species are designated. B. flammigerus and B. schach have been considered synonyms of Atractus badius since 1837. This proved to be wrong, they turned out to be valid taxa exhibiting differences in scale counts, body size, hemipenial morphology and colour pattern. Among recently collected material from Surinam the recently described A. zidoki Gasc &amp; Rodrigues was discovered and described on the basis of seven specimens. Both A. latifrons (Günther) and A....

Notes on the scientific career of Professor Dr. L. D. Brongersma, compiled at the occasion of his sixty fifth birthday
Provedor de dados: 16
Autores: Boschma, H.
For a large part the data in the present paper are based on manuscript notes in the Rijksmuseum van Natuurlijke Historie at Leiden, assembled by Brongersma himself; they form only a brief account of his scientific achievements. Efforts to completeness were only made in the composition of the List of Publications; here besides the scientific papers those with popular contents are listed. Thanks are due to Dr. W. Vervoort and to Dr. M. Boeseman for constructive remarks. Leo Daniël Brongersma was born on May 17th, 1907, at Bloemendaal (province of North-Holland); here he attended elementary school, while he went to high school in the neighbouring town of Haarlem. From 1925 to 1931 he studied zoology, botany and geology at the Municipal University of...

Autores: Hughes, B.
The characters which serve to distinguish the Gaboon Viper (Bitis gabonica) from the Rhinoceros Viper (B. nasicornis) are examined in relation to a subadult female from Dabocrom, Ghana, which displays characters of both species. It is more like B. nasicornis than B. gabonica but the admixture of B. gabonica characters is probably the result of interbreeding.

Morphological variation in two genetically distinct groups of the golden-striped salamander, Chioglossa lusitanica (Amphibia: Urodela)
Provedor de dados: 16
Autores: Alexandrino, J.; Ferrand, N.; Arntzen, J.W.
Morphometric and colour pattern variation in the endemic Iberian salamander Chioglossa lusitanica is concordant with the genetic differentiation of two groups of populations separated by the Mondego river in Portugal. Salamanders from the south have shorter digits than those from the north. Clinal variation with a south to north increase in limb, toe and finger length was found superimposed on this dichotomy, resulting in stepped clines for characters describing appendage size. Genetic variability was paralleled by colour pattern variability in the contact zone and in northern populations. To explain the observed parallels we invoke the neutral processes of vicariant isolation, admixture in a secondary contact zone, genetic drift in addition to selection...

Note on Idiopholis collaris Mocquard
Provedor de dados: 16
Autores: Brongersma, L.D.
Two species of the genus Idiopholis Mocq. have been described of which I. collaris Mocq. is said to differ from I. everetti Shelf, chiefly in possessing a small azygous shield between the internasals, and in having a yellowishwhite collar (De Rooij, 1917, p. 142). Both species apparently are very rare. During his expeditions in Central Borneo (1894-1900) Dr. A. W. Nieuwenhuis on the Upper Mahakkam river collected two small snakes which must be referred to this genus, and which agree with I. collaris in having a whitish collar, while they agree with I. everetti in lacking the azygous shield between the internasals. As these specimens also agree with the description of I. collaris as given by De Rooij (1917, p. 142, fig. 58) with regard to the relative...

A new name for Mabuya Polytropis occidentalis Hoogmoed, 1974

Autores: Hoogmoed, M.S.
In a revision of West African Mabuya species in 1974, I described Mabuya polytropis occidentalis from Ghana and Liberia. Recently Dr. R. I. Crombie kindly drew my attention to the fact that by doing so, I had created a junior homonym of Euprepes occidentalis W. Peters, 1867, currently considered a valid species of Mabuya, occurring in Southwestern Africa (Fitzsimmons, 1943). This is true and obviously due to gross negligence on my part. Therefore the West African M. polytropis occidentalis Hoogmoed, 1974 is hereby renamed M. polytropis paucisquamis, in reference to the low numbers of scales in this subspecies as compared to the nominal subspecies.

New distribution data for Podocnemis erythrocephala (Spix) with remarks on some other turtle taxa (Reptilia: Chelonia: Pelomedusidae)
Provedor de dados: 16
Autores: Hoogmoed, M.S.; Avila-Pires, T.C.S. de.
During fieldwork in the Lago de Faro, the lower reaches of the Rio Nhamundá, on the border of the Brazilian states of Pará and Amazonas, several species of pelomedusid turtles were observed. Podocnemis erythrocephala and P. unifilis occur in the area and breed there; P. expansa seems to be absent or at least very rare, though it does occur nearby in the Rio Trombetas. A single specimen of Peltocephalus dumeriliana was collected opposite the Ilha dos Maicós in a small igarapé emptying in the Rio Trombetas. It is concluded that the distribution area of Podocnemis erythrocephala is more extensive than recently thought.

New Osornophryne (Amphibia: Anura: Bufonidae) from the Atlantic Versant of the Andes in Ecuador
Provedor de dados: 16
Autores: Hoogmoed, M.S.
Two species of the little known genus Osornophryne are described from the Atlantic (Amazonian) versant of the Andes in Ecuador. O. guacamayo spec. nov. occurs at 2100 m, has well developed cranial ridges, rather peculiar feet with toes IV and V of about equal length and much longer than the others. It is rather gaudily patterned with black and yellow. O. antisana spec. nov. occurs at 3600 m and has a pointed snout, indistinct cranial ridges and is rather drably coloured. The single available adult male has a cloacal tube that runs down the back of the thighs and opens ventrally. It is speculated that this peculiar structure is indicative of internal fertilization. It is concluded that inguinal amplexus in this genus is not a primitive, but an advanced...

A study on the Gut contents of six Leathery Turtles Dermochelys Coriacea (Linnaeus) (Reptilia: Testudines: Dermochelyidae) from British waters and from the Netherlands
Provedor de dados: 16
Autores: Hartog, J.C. den; Nierop, M.M. van.
Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have...

The species of Stegonotus (Serpentes, Colubridae) in Papua New Guinea
Provedor de dados: 16
Autores: Mcdowell, S.B.
INTRODUCTION Currently, New Guinea Stegonotus with 17 scales at midbody and divided subcaudals are identified as S. modestus. But this will not account for the disparity in dentition within "S. modestus", nor the colour differences even at one locality, nor that in East and West Sepik Districts there are three quite distinct "S. modestus": (1) a large form with high ventral count and high tooth count; (2) a small form with low ventral count but high tooth count; and (3) a medium-sized form with high ventral count but low tooth count (fig. 1). The material in the British Museum and American Museum of Natural History indicates that scale count does not correctly identify the species, and that such features as dentition, form of the palatine bone, scale pits,...

A new scincid lizard of the genus Tribolonotus from Manus Island, New Guinea
Provedor de dados: 16
Autores: Cogger, H.G.
INTRODUCTION The scincid lizards of the genus Tribolonotus are generally dull-coloured, armoured, thigmothermic, cryptozoic lizards with several unique features in their morphology and biology. These features include the possession of abdominal glands and volar pores, a vestigial left oviduct, the production of a single egg or young (in all species so far investigated) and an ability to vocalize (in at least one species) otherwise unknown within the family Scincidae. As a result of two recent papers (Zweifel, 1966; Greer &amp; Parker, 1968) the taxonomy of the genus is firmly based, while many aspects of the biology and ecology of various species have been documented. In the course of field work in New Guinea in 1969, as part of Program Β of the 1969...

Unexpected diversity of slow lorises (Nycticebus spp.) within the Javan pet trade: implications for slow loris taxonomy
Provedor de dados: 16
Autores: Nekaris, K.A.I.; Jaffe, S.
Since the 1950s, Sundaland (Borneo, Java, Sumatra and their surrounding islands) was thought to be inhabited by a single slow loris species, the greater slow loris Nycticebus coucang. Early taxonomies as well as recent morphological and genetic studies, however, point to at least three species native to this region: N. coucang, N. menagensis, and N. javanicus. In the light of this taxonomy, all Sundaland slow lorises, previously considered Least Threatened, have been listed as Vulnerable or Endangered. Of particular concern is the fact that slow lorises are the most common protected primate species in the rampant Southeast Asian pet trade, resulting in their recent transferral to CITES Appendix I precluding all international commercial trade. Due to lack...

Provedor de dados: 16
Autores: Brongersma, L.D.
An interesting collection of subfossil animal remains from cave deposits in the island of Flores (Lesser Sunda Islands) was brought together by Dr. Th. L. Verhoeven. The collection includes numerous remains of mammals (Hooijer, 1957; Hooijer, in Verhoeven, 1958, pp. 262-263), as well as some vertebrae of snakes, and fragments of the skull of a Varanus species. The deposits also contain evidence of a mesolithic flake and blade industry (Verhoeven, 1952, 1953; Van Heekeren, 1957, p. 107); their age is holocene (Hooijer, 1957, p. 299: "definitely post-Pleistocene").

C'est en raison des relations qui ont toujours existées entre les Herpétologistes des divers Musées, qu'au début du siècle dernier, Schlegel a pu étudier du matériel en provenance du Muséum de Paris et décrire un certain nombre d'espèces dont les types font partie des collections de cet établissement; il nous a paru intéressant d'en publier la liste. Ainsi qu'on pourra le constater, il existe souvent, entre les dimensions des exemplaires et le décompte de leurs écailles, des différences entre nos observations et celles de Schlegel; celles-ci relèvent d'une part au fait que les exemplaires sont depuis plus d'un siècle en liquide conservateur et que d'autre part nos méthodes de décompte ne sont peut-être pas les mêmes que celles de Schlegel.

Phylogenetic relationships among extinct and extant turtles: the position of Pleurodira and the effects of the fossils on rooting crown-group turtles
Provedor de dados: 16
Autores: Sterli, J.
The origin and evolution of the crown-group of turtles (Cryptodira + Pleurodira) is one of the most interesting topics in turtle evolution, second perhaps only to the phylogenetic position of turtles among amniotes. The present contribution focuses on the former problem, exploring the phylogenetic relationships of extant and extinct turtles based on the most comprehensive phylogenetic dataset of morphological and molecular data analyzed to date. Parsimony analyses were conducted for different partitions of data (molecular and morphological) and for the combined dataset. In the present analysis, separate analyses of the molecular data always retrieve Pleurodira allied to Trionychia. Separate analysis of the morphological dataset, by contrast, depicts a more...

Since long there has been a dispute whether in the Netherlands there occur one or two species of green frogs of the genus Rana.

The first to mention Rana ridibunda ridibunda Pallas from the Netherlands were Van Kampen &amp; Heimans ( 1927), who observed that they saw a specimen of Rana esculenta var. ridibunda from Den Horn in the province of Groningen. Unfortunately they did not state where the specimen was deposited and no such specimen could be found in the collections of the Rijksmuseum van Natuurlijke Historie (RMNH) in Leiden or in the Instituut voor Taxonomische Zoölogie in Amsterdam.

Structure and function of the feeding apparatus in the common musk turtle Sternotherus odoratus (Chelonia, Kinosternidae)
Provedor de dados: 16
Autores: Natchev, N.; Heiss, E.; Singer, K.; Kummer, S.; Salaberger, D.; Weisgram, J.
The present study examined the kinematic patterns of initial food uptake, food transport, pharyngeal packing and swallowing in the common musk turtle Sternotherus odoratus. These data are supplemented by morphological descriptions of the skull and the hyolingual complex. Although the hyoid is mainly cartilaginous, S. odoratus still use exclusively hydrodynamic mechanisms in prey capture and prey transport. The tongue is relatively small, with weakly developed intrinsic musculature. We propose that the elasticity of the hypoglossum and the hyoid body impacts the capability of S. odoratus to suction feed, but allows these turtles to effectively re-position the food items within the oropharyngeal cavity during transport, manipulation and pharyngeal packing....

At the moment 36 species of lizards (6 Gekkonidae, 12 Iguanidae, 1 Scincidae and 17 Teiidae) are known for certain to occur in French Guiana. Of these 36 species, four are reported from that country for the first time (Anolis marmoratus speciosus Garman, Cercosaura o. ocellata Wagler, Prionodactylus argulus (W. Peters) and Tretioscincus agilis (Ruthven)). Moreover, there remain four species of which the occurrence in French Guiana is very likely and which presumably will be found when more lizards are collected by specialists. Eleven species were erroneously reported from French Guiana by various authors. The reasons for their removal from the list of French Guianese lizards are given.

Loveridge (1944) published a key to the species and subspecies belonging to the genus Maticora Gray. This author emphasized that a much larger material than he had at his disposal should be examined, and that all records from literature should be studied, if a clear picture of the subspecies and their ranges was to be obtained. This led me to study the forms of Maticora occurring in the Netherlands East Indies. In the present paper the subspecies of Maticora bivirgata (Boie) are discussed, and some notes on Bungarus flaviceps are given, as specimens of the latter species have been referred to Maticora by several authors.
