Further revisional notes on the Belonidae
Provedor de dados: 16
Autores: Mees, G.F.
INTRODUCTION In my recent revision of the Belonidae (Mees, 1962) a number of problems had to remain unsolved because of lack of material, and in particular because of a number of named forms the type specimens had not been available. The revision was called "preliminary" for that reason. Thanks to the co-operation of colleagues in several countries I have been able, on a round-the-world tour which lasted from February to August, 1962, to examine nearly all the types of what I had previously had to regard as species dubiae, and other type specimens, which show that in a few instances the synonymy presented in my paper is erroneous. A serious error in the key also became obvious (see under Belone punctulata). Though, inevitably, a few problems remain to be...

Notes on the genus Amphiprion Bloch &amp; Schneider, 1801 (Teleostei: Pomacentridae) and its host sea anemones in the Seychelles
Provedor de dados: 16
Autores: Hartog, J.C. den.
The genus Amphiprion Bloch &amp; Schneider, 1801, is represented in the Seychelles by two species, A. akallopisos Bleeker, 1853, and the endemic A. fuscocaudatus Allen, 1972. Throughout its distributional range Amphiprion akallopisos has exclusively been recorded to associate with the clownfish anemones Heteractis magnifica (Quoy &amp; Gaimard, 1833) and Stichodactyla mertensii Brandt, 1835. During the Netherlands Indian Ocean Programme (NIOP) Seychelles Expedition 19921993 this was confirmed for the Seychelles, although the species was predominantly found with H. magnifica, the most common host anemone in the islands. So far, Amphiprion fuscocaudatus had exclusively been reported as a symbiont of Stichodactyla mertensii. During the NIOP Seychelles...

The freshwater fishes of Java, as observed by Kuhl and van Hasselt in 1820-23
Provedor de dados: 16
Autores: Roberts, T.R.
A catalog of 79 species of freshwater fishes collected by Kuhl and van Hasselt in western Java in 1820-23 is presented, based on examination of publications, archival materials and specimens in Paris and Leiden. Archival material includes copies of their original drawings (many watercoloured) and handwritten descriptions in Latin and German or Dutch of nearly all of their new genera and species in rough drafts and in near final or final version ready for publication. A number of the descriptions, such as that of Dermogenys pusilla, include extensive anatomical and biological observations. Study of the manuscripts, drawings, and specimens has resulted in numerous reidentifications and new records, including a number of species not previously reported from...

Vaillantellinae, A New Subfamily Of Cobitidae (Pisces, Cypriniformes)
Provedor de dados: 16
Autores: Nalbant, T.T.; Banarescu, P.M.
INTRODUCTION It is generally accepted that the Eurasian freshwater fish family Cobitidae includes three main divisions, usually considered as subfamilies: Cobitinae, Botiinae and Noemacheilinae (Berg, 1940; Ramaswami, 1953; Nalbant, 1963). The two first named, in which the lateral ethmoids are movable, are usually considered closer to each other than either of them to the Noemacheilinae. The largest subfamily is Noemacheilinae; some 180 species are presently accepted as valid, most of them being still ascribed to a single genus, Noemacheilus. Quite a few other genera are accepted besides Noemacheilus, one of these being Vaillantella Fowler, 1905. Its original description (Fowler, 1905, in a footnote) is quite short, mentioning only the very long dorsal...

South American freshwater needlefishes (Belonidae) of the genus Pseudotylosurus
Provedor de dados: 16
Autores: Collete, B.B.
Pseudotylosurus Fernández Yépez is considered a valid genus of Belonidae based on the following combination of characters: depressed caudal peduncle; long narrow side branches to lateral line; pleural ribs attached to fourth vertebra; nasal papilla spatulate; lower pharyngeal plate and upper pharyngeal bones two and three elongate. Two species are recognized: Ps. microps (Günther) and Ps. angusticeps (Günther). Belone amazonica Steindachner and Deltatylosurus guayoensis Martin are synonyms of Ps. microps; Ps. brasiliensis Fernández Yépez is a synonym of Ps. angusticeps. Ps. microps reaches a larger size than Ps. angusticeps and occurs primarily in the Orinoco, the Guianas, and the lower Amazon. Ps. angusticeps is primarily a species of the upper Amazon in...

Medusivorous fishes, a review
Provedor de dados: 16
Autores: Ates, R.M.L.
A preliminary review is presented of fish species having consumed pelagic Cnidaria (Scyphozoa and Hydrozoa) as well as Ctenophora. Quantitative data are scarce. Knowledge of morphological and physiological adaptations of fishes foraging on gelatinous plankton is almost non-existent. Many fish species consume medusae and some reasons to suspect that there are even more that do so, are discussed.

First record of Rivulus marmoratus Poey, 1880 From the South American continent (Pisces: Cyprinodontidae)
Provedor de dados: 16
Autores: Taphorn, D.C.
Rivulus marmoratus Poey, 1880 has previously been found only in south Florida, Cuba, the Bahamas, Barbuda, St. Martin and several islands off the Venezuelan coast (Curaçao, Bonaire and Gran Roque) (Hoedeman, 1958; Böhlke &amp; Chaplin, 1968). In September of 1978, one of my students, Mr. Edgard W. Cabezas, brought me a specimen of this species that he had caught in the northern section of Maracaibo City, state of Zulia, Venezuela. We revisited the site, a poorly drained section of town near the western shore of the Straits of Lake Maracaibo, on 21.ix.1978 and 14.x. 1978, and collected an additional 19 specimens (15 of which are in my personal collection). Most of the fish were caught in shallow, brackish water (salinity 25°/00, temperature 3i°C) among...

On the absence of gill rakers in specimens of the Basking Shark, Cetorhinus maximus (Gunner)
Provedor de dados: 16
Autores: Deinse, A.B. van; Adriani, M.J.
In the majority of the papers dealing more or less extensively with Cetorhinus maximus the gill rakers (fanunculi) are correctly described and regarded as specifically characteristic, whilst in a number of other papers, e.g., de Blainville (1812), Vrolik (1826), and Tchang Si (1934) the gill rakers are not mentioned. This does not necessarily indicate that the specimens examined by the cited authors did not possess gill rakers, probably no definite search was made concerning the presence or absence of these parts. From 1821 till 1952 there stranded in the Netherlands or were brought ashore by fishermen 21 specimens of Cetorhinus maximus; of nine of these it was stated that they had gill rakers, four of these specimens proved to be without gill rakers,...

In het laatste geval is echter het verband verloren gegaan, dat er bestaat tussen de plaats en de bouw van de vinstraal enerzijds en de funktie daarvan anderzijds. In het kort volgt hieronder het resultaat van een onderzoekje naar de bouw en de funktie van met name de staartvinstralen, uitmondend in een vergelijking met de bevindingen van Buizer &amp; Doeksen.

The systematic position of the Chinese Fish Macrones Sinensis Bleeker (Siluroidea)
Provedor de dados: 16
Autores: Jayaram, K.C.; Boeseman, M.
INTRODUCTION Fishes of the genus Macrones Duméril (= Mystus Scopoli), family Bagridae, are mainly distributed from Syria in the north-west, through Pakistan, Ceylon, India, Bangladesh, Burma, Thailand and Malaya, to the East Indies. Thirty-eight species have been described in the genus, of which six are reported as occurring in China (Jayaram, 1966: 445). In an earlier communication (Jayaram, 1968: 294) it was surmised that the genus may not be found in China and that the six species described from that country be best left out of Chinese lists, or that they may be placed under the predominantly Chinese genus Pelteobagrus Bleeker.

Notes on the fishes of Western New Guinea I
Provedor de dados: 16
Autores: Boeseman, M.
INTRODUCTION In the summer of 1954, I received an invitation from the Netherlands New Guinea Government to undertake a faunistic investigation of the fish fauna of the area. It was thought advisable for the promotion of the local New Guinea fisheries, to first obtain a more thorough knowledge of the fish fauna of the region, based on a collection as complete as could be attained within a reasonable time. As such a collecting trip could be expected to yield results of considerable zoological and zoogeographical importance, I gladly accepted this unique opportunity. A most fortunate circumstance was that my visit coincided with an already previously planned collecting trip to the same area by two of my colleagues, Dr. L. D. Brongersma, at the time...

Polynemus multifilis Temminck &amp; Schlegel, 1843, is redescribed and its synonymy, authorship, type material status and distribution are discussed. In addition, a new species, P. kapuasensis, previously identified as P. multifilis, is described from the Kapuas River, western Kalimantan, Indonesia on the basis of 12 specimens. Polynemus kapuasensis differs from P. multifilis in having higher counts of pectoral filaments (usually 15 on each side of body vs. 14 in the latter), pored lateral line scales [mode 103 (range 100-110) vs. 86 (83- 99)], scale rows above lateral line [10 (9-11) vs. 8 (7 or 8)] and caudal peduncle scales [38 (35-40) vs. 32 (28- 37)], and a shorter pectoral fin [mean 31% (range 29-33%) of standard length], its posterior tip not...

In preparing the volume of the Gobioidea in M. Weber and L.

Of a number of these the description was distinct enough to see what was meant with such a new species, but there were several species which I could not recognize from their description. Bleeker described a large number of new species, but, unfortunately, several of his descriptions are too vague to recognize the species. So many authors had described several species which proved, after comparison with Bleeker's type specimens or descriptions made after his types, to be either closely allied, or identical with species...

Fish microfossils from Ramsåsa, site E, Scania, southern Sweden (mid Palaeozoic)
Provedor de dados: 16

Material from three pieces of rock from Ramsåsa, site E, was divided into size fractions 0.106, 0.212, 0.355, 0.425 and 0.5 mm. Larger sizes were absent. The three assemblages were examined and compared with each other, also per fraction, and with residue samples from site E. The latter are proportionately not representative of the faunas of which they must have been part, specimens measuring 0.5 mm or more. The residue labels refer to Ørvig and his student Peyel. The results of the comparison between the assemblages from the rocks and from the residues are hardly complementary. Thelodont scales were obtained almost exclusively from the pieces of rock; acanthodian ‘modified trunk’ scales, spines and jawbones and rare birkeniid remains were restricted to...

Mechanism of the jaw and body muscles of Orthragoriscus mola L.
Provedor de dados: 16
Autores: Roon, J.M. van; Pelkwijk, J.J. ter.
There are several descriptions of the anatomy of Orthragoriscus mola L., but no authors except Van Dobben (1935) have given a functional treatise concerning the mechanism of the jaw. Unfortunately the fish described by Van Dobben seems to have been abnormal. The description which follows is based on anatomical study of two sunfishes which stranded on the Dutch coast and were placed at our disposal by the Rijksmuseum van Natuurlijke Historie, Leiden. Specimen A, a female, stranded December 10, 1935 near Burgh, in the neighbourhood of Haamstede, on the Isle of Schouwen. It has been used for a cast in the Leiden Museum and was dissected by Dr N.

Autores: Stigchil, J.W.B. van der.
In 1955, the late Dr. O.

Only a series of eight apparently conspecific specimens is discussed here. At first sight, the present specimens appear to closely resemble Pimelodella griffini Eigenmann, especially six examples with a prolonged first soft dorsal ray. However, excepting several minor differences, P. griffini has the dorsal spine prolonged instead of the first ray, while it has the adipose dorsal fin much shorter.

Rejecting without valid argumentation a lectotype selection for Raja kenojei Müller &amp; Henle, 1841, by the present author (1947), Ishiyama (1967) indicated another of the four Leiden types as such. Both selected specimens are shown to represent only the different sexes of the same species, which is not conspecific with R. kenojei sensu Ishiyama et al. (= ? R. japonica Nyström, 1887) but rather with R. porosa Günther, 1847, as understood by Ishiyama. One of the R. kenojei types is referred to R. meerdervoortii Bleeker, 1860, a distinct species not identical with R. kenojei in either interpretation, and of which R. macrophthalma Ishiyama, 1950, may well prove to be a junior synonym. Müller &amp; Henle's coloured illustration of R. kenojei, made after a...

A systematic revision of the piscivorous haplochromine Cichlidae (Pisces: Teleostei) of Lake Victoria (East Africa). Part I
Provedor de dados: 16
Autores: Oijen, M.J.P. van.
The distinction between Harpagochromis and Prognathochromis, and the distinction between these and other cichlid genera of Lake Victoria as proposed by Greenwood (1980), is demonstrated to be artificial. The BM(NH) collections of Haplochromis dichrourus and H. pellegrini were found to be polyspecific and are redescribed. On the basis of specimens formerly included in H. pellegrini a new species is described. Five new species are described based on material from the Mwanza Gulf and Maisome Island. Specimens of H. dichrourus from different areas of Lake Victoria are described separately to demonstrate geographic variation.

A preliminary revision of the Belonidae
Provedor de dados: 16
Autores: Mees, G.F.
INTRODUCTION Difficulties with the identification of some West-Indian Belonidae and an investigation into the merits of the generic name Strongylura as against Tylosurus led to a revision of the Belonidae, the result of which is published here. As will be seen on the following pages, this revision is by no means final; many problems remain to be solved, much synonymy given here is doubtful, lack of material prevented me from investigating the possible presence of slight geographic variation in the widely distributed species; some apparently valid species are left out altogether (I listed their names on p. 5) because no material has been available, and other names remain doubtful as it has not been possible to examine the type specimens. There is also the...

The types of Bleeker's Indo-Pacific Elopoid and Clupeoid Fishes
Provedor de dados: 16
Autores: Whitehead, P.J.P.; Boeseman, M.; Wheeler, A.C.
Pieter Bleeker described 72 new species and 10 new genera of elopoid and clupeoid fishes from the Indo-Malayan Archipelago. From amongst the Bleeker material in the Rijksmuseum van Natuurlijke Historie in Leiden and the British Museum (Natural History) in London, it has been possible to find the holotypes or designate lectotypes or putative neotypes for almost all these species. The types are fully described, with notes on synonymies and affinities. Of the species listed, 24 are considered senior synonyms, and 5 Bleeker genera are accepted.

Redescription of Gobius cauerensis (Bleeker, 1853), with discussion of the validity of the species
Provedor de dados: 16
Autores: Randall, J.E.; Greenfield, D.W.
Thacker (2004b) regarded the gobiid fish Gnatholepis cauerensis (Bleeker) as a synonym of Gnatholepis anjerensis (Bleeker) and treated G. scapulostigma Herre as the replacement name for what other recent authors had identified as G. cauerensis. The holotype of Gobius cauerensis Bleeker from the Nationaal Natuurhistorische Museum in Leiden is redescribed. Because its colour pattern has faded, the original Bleeker painting is reproduced, the diagnostic colour features noted, and comparison provided with an underwater photograph taken of a specimen before it was collected in the Mentawai Islands (near the type locality of Kauer, Sumatra). Gnatholepis cauerensis is a valid species distinct from G. anjerensis. G. scapulostigma Herre is returned to the synonymy...

On a collection of fishes from Stanley Pool (Belgian Congo)
Provedor de dados: 16
Autores: Boeseman, M.
From Mr. A. Werner, collector and animal dealer at Munich, Germany, the Leiden Museum received a collection of 1012 well preserved specimens of fishes from Stanley Pool (Léopoldville), Belgian Congo. As several species proved to be new for this locality and are not mentioned in Poll's paper on the fishes from Stanley Pool (1939), the following publication was considered worth while. Moreover, a new Synodontid species, Synodontis werneri, is described. In the present report, the various species are recorded in the same order as in Poll's account. The name of the locality, being always the same, is omitted further on. Protopterus dolloi Boulenger 2 ex., January 1956, 76-91 mm. Both specimens are juvenile and have the tail slightly mutilated.

Since the publication of a paper on Auchenipteridae and Pimelodidae (Mees, 1974), I have received additional material of several of the genera there revised. This material includes a new species of Pseudopimelodus from Venezuela, increasing the number of species of that genus to six (two of which have several subspecies), and a new species of Microglanis from Ecuador, the eighth member of its genus. The main purpose of this paper is the description of these two new species. In addition, fresh material of Microglanis iheringi, a species of which previously I had examined only a single specimen, enabled me to supply some additional notes on it as well as an illustration showing its distinctive characters much better than do the photographs published by Gomes...

The zooplanktivorous Haplochromis tanaos spec. nov., and the morphologically very similar but insectivorous Haplochromis thereuterion spec. nov., from Lake Victoria (East Africa) are described and compared to Haplochromis diplotaenia Regan &amp; Trewavas, 1928, a similar species which is known only from the holotype. Intraspecific variation is described for both new species. Ecological data of the new species are compared to those of known zooplanktivores and insectivores from the Mwanza Gulf area. Both new species disappeared concurrently with the Nile perch (Lates) upsurge early in the 1980's. The recent occurrence of individuals closely resembling the new species, in a different habitat close to the original one, is analysed.

A preliminary list of Surinam fishes not included in Eigenmann's enumeration of 1912

Autores: Boeseman, M.
In his valuable report on the freshwater fishes of British Guiana, Eigenmann (1912, pp. 64-73) gave a list of the species, together with comparable lists on the freshwater fishes of the adjacent regions. In sharp contrast with the number of 266 species reported from the Essequibo area only, the total amount of Surinam species proved to be but 118! Although since Eigenmann compiled these lists some more species have been reported from Surinam, the general situation has remained essentially the same, clearly showing the backward state of ichthyological research in this area. A possibility to improve our knowledge of this subject came when during the last four years the Rijksmuseum van Natuurlijke Historie received several more or less extensive collections...

Provedor de dados: 16
Autores: Nijssen, H.; Isbrücker, I.J.H.
Hypopygus lepturus Hoedeman, 1062, was hitherto known from the holotype and one paratype only, both imported aquarium specimens. In this paper the type locality of the species is restricted. Additional distributional data from Surinam are given, together with records on the occurrence of H. lepturus in Guyana, Venezuela, Colombia, Brazil, and on the very likely occurrence in Peru. Comparative notes on Steatogenys elegans (Steindachner, 1880) sensu Boulenger, 1898, are added because of the similar appearance of both species. The synonymy of Tateichthys duidae La Monte, 1929, with Steatogenys elegans is established.

Triodon macropterus versus Triodon bursarius : an attempt to establish the correct name and authorship
Provedor de dados: 16
Autores: Boeseman, M.
A visit to the Leiden Museum by Professor Dr. L. F. de Beaufort, assembling data for his next volume on the Fishes of the Indo-Australian Archipelago, prompted me to investigate the nomenclatorial difficulties still existing around the Plectognath genus Triodon and its single known species. One of the principal items consulted, Herre's 1953 Check List of Philippine Fishes, itself not without serious flaws and therefore illustrative for the present problem, proved a very satisfactory starting-point, especially as it contains the only recent and rather extensive compilation of previous literature on the subject. Still, Herre's enumeration of references is not at all exhaustive, and numerous additions taken both from systematic literature and from general...

Effect of introduced species and habitat alteration on the occurrence and distribution of euryhaline fishes in fresh- and brackish-water habitats on Aruba, Bonaire and Curaçao (South Caribbean)
Provedor de dados: 16
Autores: Hulsman, H.; Vonk, R.; Aliabadian, M.; Debrot, A.O.; Nijman, V.
We conducted an ichthyological survey during the dry season of 2006 on the semi-arid islands of Aruba, Bonaire and Curaçao to provide information on species composition, richness and distribution in natural and non-natural aquatic habitats. The dry season species assemblages (N = 9 species) comprised less species than the wet seasons, and these data refine our knowledge of the indigenous fish fauna and its refuge localities during phases of drought and ensuing high salinity. A hierarchical cluster analysis reveals that the three islands have different species compositions with Curaçao being the most diverse, probably due to its having the most habitats and freshwaters present throughout the year. Species richness was unrelated to salinity and species...

The gadid fish, Gaidropsarus pacificus, originally described as Motella pacifica by Temminck &amp; Schlegel (1842) is reduced to a junior synonym of Rhinonemus cimbrius (Linnaeus, 1758).

Opinions are divided in relation to what generical name has priority, Heliacus or Torinia. In proof of this I will quote, leaving aside those of many others, the opinions of two authorities. Thiele [1918, p. 80 (114)] writes: "Bezüglich des Namens Torinia bemerkt Iredale, dass ihm Heliacus Orbigny, weil älter, vorzuziehen sei; es mag sein, dass dieser Name ein wenig älter ist — nach Hermannsen von 1841, nach Iredale 1842, es scheint also die Zeit des Erscheinens nicht ganz festzustehen —, während Torinia von Gray 1842 auf die Beschaffenheit des Deckels hin begründet worden ist". The opinion of Tomlin (1928, p. 333), however, is quite different: "Gray in Proc. Zool. Soc., 1847, Ρ· 151, gives his own genus Torinia precedence, quoting it as of 1840 and 1842....

Daar een dergelijk overzicht tot nu toe niet werd gepubliceerd, en vele gegevens van belang verspreid zijn in min of meer ontoegankelijke kranten en periodieken, leek het wenselijk deze in iets gewijzigde vorm hier te reproduceren. Ten overvloede zij vermeld dat, gezien de aard van de bronnen, ook dit overzicht wellicht geen aanspraak kan maken op volledigheid. Van de zeer omvangrijke groep der meervallen (ongeveer 2100 soorten) komt slechts een enkele soort in Nederland voor, en slechts twee in Europa (Silurus glanis Linnaeus en Parasilurus aristotelis...

Autores: Boeseman, M.
In 1953, Mr. E. C. Stol, naturalist at Leiden, kindly placed at my disposal a small collection of Surinam freshwater aquarium fishes. A second collection, consisting of freshwater and marine specimens from Surinam, mainly collected by Dr. D. C. Geijskes and Mr. H. W. Lijding (Fishery Department), was received during 1954. As the two collections proved to contain several interesting specimens belonging to species not yet reported from Surinam, the following enumeration is given. To the measurements of specimens with damaged caudal fins the mark is added. Dasyatis guttata (Bl.; Schn.) 1 ex., near lightship Surinam River, 5-8 miles E., 12 January 1954, H. W.

Zoological notes from Port Dickson : II. A small collection of fishes from Malaya
Provedor de dados: 16
Autores: Koumans, F.P.
During the stay of the Nica-detachment at Port Dickson, Malaya, in March 1946, a small collection of fishes was made, which was presented by Major Dr. L. D. Brongersma to the Rijksmuseum van Natuurlijke Historie at Leiden. Besides these fishes from Malaya, two specimens of flying fishes from the Indian Ocean were presented. The collection from Port Dickson was pretty small, 45 specimens in total, belonging to 25 species. It gives therefore by no means an idea of the fishfauna of Malaya. The fishfauna of the Westcoast of Malaya is still imperfectly known, so even this small collection can contribute to the knowledge of this fauna. The species are arranged according to the system followed by M. Weber &amp; L. F. de Beaufort in their Fishes of the...

On some fossil fish remains from Java
Provedor de dados: 16
Autores: Koumans, F.P.
During his paleontological searches in Java, the late Prof. Eug. Dubois collected a number of fossil fish remains. His searches were instituted mainly in pleistocene deposits, and as far as I am aware these fish remains were the first of their kind to be collected in Java in strata of that age. This, and the fact that Dubois (1907, 1908) referred to these fish in two preliminary papers, gives this collection additional interest. In the first of his preliminary papers, Dubois (1907, p. 455) mentions the following fish: Anabas microcephalus, Clarias magur, Ophiocephalus, Carcharias gangeticus. In the second paper, Dubois (1908, p. 1239) mentions that at least seven species of freshwater fish are represented in his collection, viz., Anabas microcephalus,...

I propose in this part of my catalogue of the Solariidae to deal only with the genus Solarium s.s. and to reserve the remaining genera of this family for the next publication. For the division of the Solariidae in genera I followed Thiele's Handbuch der systematischen Weichtierkunde, also as far as concerns the names. Not only did I mention those species of which we possess specimens in the Leiden Museum, but, like in the former catalogues, I have included also, as far as possible, those species of which no material is present in our collections. The list is composed on the same lines as my previous ones. Of all species of which we possess material a list is given of the specimens, stating: 1) the letter which indicates specimens from the same locality and...

A note on the genus Liocranium Ogilby (Pisces, Scorpaenidae)
Provedor de dados: 16
Autores: Mees, G.F.
The genus Liocranium was established by Ogilby (1903) to contain a new species of scorpion-fish from the east coast of Queensland: L. praepositum. The genus remained monotypic until McCulloch (1921) placed Paracentropogan scorpio Ogilby in it, a species also described from the Queensland coast. Whitley (1933) did not agree, and transferred P. scorpio to a separate new genus Vadesuma. In the meantime Weber (1913) described as Paracentropogon pleurostigma and Paracentropogon cynocephalus two scorpion-fishes from the East Indies. These two species, however, were not well placed in Paracentropogon, and therefore De Beaufort (1949) created the genus Sibogapistus for them. Apart from McCulloch's (1921) remark that: "Paracentropogon cynocephalus Weber is perhaps...

The Malayan Cyprinoid fishes of the family Homalopteridae
Provedor de dados: 16
Autores: Alfred, E.R.
INTRODUCTION The Homalopteridae comprise small, loach-like fishes that occur in rapids, riffles and other fast-flowing parts of streams and rivers throughout the mainland of Malaya. In his monographic study, Silas (1953) reported six species from Malaya, viz., Homaloptera Zollingeri Bleeker, H. wassinki Bleeker, H. orthogoniata Vaillant, H. tweediei Herre, H. leonardi Hora and Neohomaloptera johorensis Herre, while Tweedie (1952) recorded H. ocellata Van der Hoeven and I described H. ogilviei Alfred (1967). In the present account, the earlier records of H. zollingeri, H. wassinki and H. ocellata are relegated to synonymy. Nine species, all of the genus Homaloptera Van Hasselt, are described, including a new record and two new species. Fowler's...

Autores: Mees, G.F.
In April 1980, Mr. P. Planquette of the Laboratoire d'Hydrobiologie, PetitBourg, Guadeloupe, presented me with a collection of naked catfishes from French Guiana, which he had brought together in the course of an ichthyological survey of that country, carried out between September 1978 and March 1980. The survey continues and in September 1981 a few additional specimens were received from Mr. R. Rojas-Beltrán, who is collaborating with Mr. Planquette in the project. The material consists of 19 species belonging to six families: Auchenipteridae (six species), Aspredinidae (one species), Pimelodidae (nine species), Helogeneidae (one species), Trichomycteridae (one species) and Cetopsidae (one species). The Aspredinidae are represented by a single specimen...

Late Silurian fish microfossils from Ramsåsa (sites D and ‘south of church’), Skåne, south Sweden
Provedor de dados: 16
Autores: Vergoossen, J.M.J.
The microvertebrate assemblages from Ramsåsa sites D and ‘south of church’, Skåne, south Sweden are described for the first time. Analysis of these microvertebrate assemblages from the Öved Sandstone Formation of Skåne indicates a Ludlow rather than Pridoli age. One of two faunas from Ramsåsa site D contained the zonal fossil Thelodus sculptilis and the other T. sculptilis in association with Paralogania ludlowiensis and Thelodus carinatus. The presence of T. carinatus is the youngest record of this species in Laurussia, and indicative of the transitional phase between the Andreolepis hedei and T. sculptilis Zones of the East Baltic Microvertebrate Standard. A fauna with Thelodus parvidens, from south of Ramsåsa church, proved only broadly datable as...

On the identity of Arius oncinus R. H. Schomburgk (Pisces, Nematognathi, Auchenipteridae)

Autores: Mees, G.F.
The catfish which R. H. Schomburgk (1841b: 173, pl. 4) named Arius oncinus *), from a description and a drawing made in the field, has remained a puzzle to ichthyologists ever since. It is true that it has been recognized that Arius oncinus is not an Arius but belongs to the Auchenipteridae. Günther (1864: 194) merely listed the name in a footnote under Auchenipterus, without being able to do anything with it. Eigenmann &amp; Eigenmann (1890: 266) referred to it as a "doubtful species of Centromochlus". Gosline (1945: 10) included it without comment in the genus Centromochlus under the name C. oncinus, but the only reference given is to the Eigenmanns and in the absence of material the name remained as problematic as ever. Fowler (1951) made no mention of...

Age, size and vertebral calcification in the basking shark, Cetorhinus maximus (Gunnerus)
Provedor de dados: 16
Autores: Parker, H.W.; Stott, F.C.
ABSTRACT The inshore shoals of basking sharks that appear in spring off the western seabord of Europe have been variously claimed to be part of a seasonal south to north migration, or local, perhaps nuptial, aggregations. The decline in the catches of the Achill Island Fishery in the last decade suggests that the size of the shoals has diminished there. Size/frequency analysis of available records shows a midsummer peak of specimens with a mean length of 3.09 m and a mid-winter peak at 3.52 m; the difference is significant and is ascribed to growth. From this value, coupled with the recorded maximum and minimum sizes, a hypothetical asymptotic growth-curve is calculated. Comparison of this age/length relationship with the observed relationship between...

Autores: Mees, G.F.
Very soon after publication of a description of a new species of Therapon from Western Australia (Mees, 1963), I became aware that I had misidentified one of the species mentioned in the discussion of the affinities of the new species. Originally I intended to write only a short supplementary paper, to rectify the error, but as more material became available, my notes expanded, until it appeared to me that longer postponement of their publication would not be likely to add much of significance. The paper as now published falls far short of a revision; rather, it contains a number of scattered notes on various species, adding, I hope, a little to knowledge of their distribution and affinities, and for that reason I have given it its somewhat vague title....

Revision of the fishes collected by Burger and Von Siebold in Japan

INTRODUCTION The collections made by Burger and Von Siebold during the second quarter of the previous century, in the neighbourhood of Nagasaki, were so extensive that they gave Temminck &amp; Schlegel the opportunity to build the foundation for the knowledge of the Japanese ichthyofauna. In her publication "'s Rijks Museum van Natuurlijke Historie, 1820-1915", Dr. A. Gijzen states: "Burger sent among others fishes"; "25 December 1832 Temminck gives him a list of the desired species of animals." As she further states, Burger's position in Japan is not quite clear; in a letter from 9 November 1839, Temminck writes to the Minister that he knows Burger as a collector only, but that he knows no further particulars about him.

1. ABOUT THE NOMENCLATURE OF THE SPECIES OF FISTULARIA. The species of Fistularia have caused much trouble and misunderstanding as to their proper names. Formerly there were 2 species known, in Günther's Catalogue 2) distinguished as F. tabaccaria L. and F. serrata Cuv. F. tabaccaria is restricted to the tropical Atlantic and easily distinguished by the upper lateral edge of the snout (formed by the prefrontal and metapterygoid) which is nearly smooth, being only slightly crenulated in the adult, and by the blue spots and stripes on the upper parts of head and body. F. serrata Cuv. is immaculate, the upper lateral edge of the snout sharply serrated and its habitat in all tropical seas. In 1880 Günther 3) found, that his F. serrata Cuv. contained two...

In 1939 J. M. van Roon and J. J. ter Pelkwijk published some data on two specimens of Orthragoriscus mola (L.) stranded on the Dutch coast. Measurements of bones and muscles of the jaw were given on account of the functional treatise concerning the mechanism of the jaw of Orthragoriscus given by Van Dobben (1935), based upon one specimen that differed in many ways from both individuals we dissected. In the following years, we got three more specimens and an examination of the jaw muscles proved them to be fully agreeing with the two fishes described before. It seems worth while to publish corresponding data and measurements. Specimen C, a female, stranded December 12, 1939 near Kamperduin in the neighbourhood of Schoorl.

Notes on South American catfishes, including remarks on Valenciennes And Bleeker types in the Leiden Museum
Provedor de dados: 16
Autores: Boeseman, M.
I A recent perusal of Valenciennes' accounts on the nematognathous fishes (Valenciennes in Cuvier &amp; Valenciennes, 1839, 1840) showed that of the numerous South American species newly described or renamed, eighteen wholly or partly were based on specimens in the collection of the Rijksmuseum van Natuurlijke Historie at Leiden. It was surprising to find that most of these specimens are stated to have been sent to Leiden from Cayenne, and only a few from Surinam, for most of the pre-1839 South American catfishes in the Leiden Museum are of Surinam origin and few, if any, from Cayenne. Moreover, an examination of the collection showed that up to recently none of the specimens belonging to the pertinent species bear any indication as to a typical status. On...

Autores: Boer, P.
INLEIDING Het Nederlands Instituut voor Onderzoek der Zee heeft gedurende vele jaren incidentele en gerichte gegevens verzameld van diersoorten voorkomend langs de Nederlandse kust. Daartoe werden vanaf 1932 regelmatig aan leden van de Helderse vissersvloot premies betaald voor het aanbrengen van o.a. bijzondere zeedieren. Zeevissen namen een belangrijke plaats in. Vele van de op deze wijze aangevoerde vissen werden gevangen in het kustgebied van IJmuiden tot de Duitse Bocht. In Nederland komen 137 soorten zeevissen voor, waarvan het voorkomen min of meer bekend is. De algemene soorten worden òf regelmatig door beroepsvissers gevangen en deze vangsten worden dan eens per jaar in de visserij statistieken gepubliceerd, òf regelmatig door onderzoekingsschepen...

Notes on new or rare marine fishes from Surinam
Provedor de dados: 16
Autores: Boeseman, M.
The fish collection of the Leiden Museum has recently been enriched by the donation of a few small or moderate collections of fishes assembled in tropical Atlantic America. As these proved to contain some representatives of species rarely encountered or even new to science and, moreover, provided interesting distributional information, publication of a few notes containing the principal data seems of interest. Note I. — A collection of about 40 specimens from Surinam, representing 29 species mostly marine, was received from Ir. Z. Salverda, who appears to have collected them himself. Unfortunately, Ir. Salverda omitted adding more detailed locality information, but all marine species can be expected to occur throughout the whole of the coastal region. Two...

Late Silurian fish microfossils from Klinta and Rinnebäcks Bro (Scania, south Sweden), with remarks on the morphology of Nostolepis striata trunk scales
Provedor de dados: 16
Autores: Vergoossen, J.M.J.
The microvertebrate faunas from ten small pieces of rock from the Öved Sandstone Formation at Klinta (1-10) yielded osteostracan, heterostracan, thelodont, and acanthodian remains, dated here as Whitcliffian. The most important age indicators are the heterostracan Archegonaspis and the thelodont zonal fossil Thelodus sculptilis. The latter taxon is also present in a small Whitcliffian fauna from the Öved Sandstone Formation at Rinnebäcks bro, together with other thelodont and acanthodian remains. From Rinnebäcks bro no previous records of Silurian fish fossils exist. In an attempt to gain a better understanding of nostolepid trunk scale variation and to develop an instrument to assess this variation, seven Nostolepis striata trunk scales from Klinta are...

Phenotypic variation in the Snowtrout Schizothorax richardsonii (Gray, 1832) (Actinopterygii: Cypriniformes: Cyprinidae) from the Indian Himalayas
Provedor de dados: 16
Autores: Mir, F.A.; Mir, J.I.; Chandra, S.
We investigated intraspecific variation of the Snowtrout, Schizothorax richardsonii on the basis of morphometric characters. Altogether, 217 specimens were collected from four rivers in the Western and Central Indian Himalaya. A truss network was constructed by interconnecting 14 landmarks to yield 31 distance variables that were extracted from digital images of specimens using tpsDig2 and PAST software. Transformed truss measurements were subjected to univariate analysis of variance, factor analysis and discriminant analysis. All variables exhibited significant differences between the populations. Altogether 86.6% of the specimens were classified into their original populations (82.9 % under a ‘leave-one-out’ procedure). With factor analysis measurements...

Ray-finned fishes (Osteichthyes, Actinopterygii) from the type Maastrichtian, the Netherlands and Belgium
Provedor de dados: 16
Autores: Friedman, M.
Ray-finned fishes are a diverse, but understudied, component of the Maastrichtian marine fauna of the southeast Netherlands (Limburg) and northeast Belgium (Liège-Limburg). The most extensive reviews of fishes from these uppermost Cretaceous deposits were made in the early and mid-Twentieth Century, but little research on this important assemblage has been executed since. The present paper provides figures and brief descriptions of fishes from the Maastrichtian type area as an aid for field identification of fossil discoveries. A simple key to common Maastrichtian fish teeth from this area is also included. All convincing records of ray-finned fishes from the Maastrichtian of the Netherlands and Belgium, inclusive of the Mons Basin, are teleosts, and...

Parvilux, a new genus of Myctophid fishes from the Northeastern Pacific, with two new species
Provedor de dados: 16
Autores: Hubbs, C.L.; Wisner, R.L.
A relatively gigantic species of lanternfish, described below as representing a new genus, has appeared sparingly since 1950 in bathypelagic collections from off southern California and northern Baja California, Mexico. Although the distinctness of the species has been known for some time, most available specimens had generally been so badly damaged by the nets that an adequate evaluation of the various characters was not possible. Due to a recent increase in collecting effort in these regions, and to the use of a very large midwater trawl, more specimens have been taken than were before available, and a number of these are in a sufficiently good condition to permit the drawing of rather firm conclusions regarding the reliability and constancy of the...

When, in the fall of 1947, my predecessor, Dr. F. P.

Dubois (1907; 1908), still remained to be investigated or re-examined. I gladly accepted the opportunity to complete the research on this interesting material. A considerable part of these fossil remains, labelled by Dr. Koumans (but not mentioned in his paper, 1948, p. 80) as "16 fragments of skullbones", which "probably belong to Ophicephalus spec." (no. 11640), still proved to be in a sufficient state of preservation to permit an accurate identification of the bones these fragments must represent, as well as of the kind of fish to which the greater part...

During recent research on a small number of freshwater sharks from Lake Jamoer, Netherlands New Guinea, I was struck by the fact that the consulted literature clearly showed a deplorable lack of agreement in the choice of a generic name for the species belonging to the genus Carcharhinus Blainville, sensu Bigelow &amp; Schroeder (1948, p. 320), even among recent authors. Though by far the majority of contemporary authors now seem to have accepted Carcharhinus, a decreasing number still uses either Galeolamna Owen or Eulamia Gill, or occasionally even Carcharias Cuvier. In the restricted list of literature given at the end of the present paper, eleven of the post-1900 authors finally used Carcharhinus (or Carcharinus), only two used Galeolamna (Whitley,...

The generic classification of the haplochromine cichlids of Lake Victoria, East Africa
Provedor de dados: 16
Autores: Oijen, M.J.P. van.
In chronologic order of publication, all papers dealing with the systematics of haplochromine cichlids of Lake Victoria are analysed with regard to the generic classification of the species. Taxonomists have disputed and changed the generic classification soon after cichlids from Lake Victoria were first described. At the turn of the century, different opinions among taxonomists working on Lake Victoria haplochromines were mainly based on the fact that they studied different material. The study of more extensive collections yielded the impression that differences between the species are gradual, rendering the delimitation of genera problematic. Recently, an attempt to use cladistic methods for the unravelling of the phylogeny of the haplochromines has...

A collection of Surinam fishes, all probably collected in the neighbourhood of Paramaribo during the late autumn of 1952, was kindly presented to the Rijksmuseum van Natuurlijke Historie at Leiden by the direction of the Rotterdam Zoological Garden „Blijdorp". The collection contains some 800 specimens, the examination of which yielded sufficiently interesting results to justify the present publication. Order OSTARIOPHYSOIDEA Family CHARACINIDAE Curimatopsis macrolepis Steindachner 1 ex., neighbourhood of Paramaribo, standard length 26 mm (caudal fin damaged).

Description of Poecilia (Acanthophacelus) wingei n. sp. from the Paría Peninsula, Venezuela, including notes on Acanthophacelus Eigenmann, 1907 and other subgenera of Poecilia Bloch and Schneider, 1801 (Teleostei, Cyprinodontiformes, Poeciliidae)
Provedor de dados: 16
Autores: Poeser, F.N.; Kempkes, M.; Isbrücker, I.J.H.
The taxonomy of the common guppy, Poecilia reticulata Peters, 1859, is reviewed and the closely related Campoma guppy, P. wingei n. sp., is described. Formerly, the common guppy was not judged to be closely related to any other species of Poecilia, but the new species is the second species to be allocated in the subgenus Acanthophacelus Eigenmann, 1907. The recognition of P. wingei results from observed character displacement, i.e., on the interaction between two closely related species in a shared environment. In addition to differences in coloration, behaviour also indicates specific differences. The area in which P. wingei occurs, the Campoma region at the base of the Paría Peninsula in Venezuela, hints to an origin of the subgenus Acanthophacelus prior...

Ancyrocephalidae (Monogenea) of Lake Tanganyika: does the Cichlidogyrus parasite fauna of Interochromis loocki (Teleostei, Cichlidae) reflect its host’s phylogenetic affinities?
Provedor de dados: 16
Autores: Pariselle, A.; Van Steenberge, M.; Snoeks, J.; Volckaert, F.A.M.; Huyse, T.; Vanhove, M.P.M.
The faunal diversity of Lake Tanganyika, with its fish species flocks and its importance as a cradle and reservoir of ancient fish lineages seeding other radiations, has generated a considerable scientific interest in the fields of evolution and biodiversity. The Tropheini, an endemic Tanganyikan cichlid tribe, fills a peculiar phylogenetic position, being closely related to the haplochromine radiations of Lakes Malawi and Victoria. Several problems remain regarding their genus-level classification. For example, the monotypic genus Interochromis is phylogenetically nested within Petrochromis; its only representative, I. loocki, has often been reclassified. As monogenean flatworms are useful markers for fish phylogeny and taxonomy, the monogenean fauna of...

On Sciadeichthys (Selenaspis) Walrechti, a new South American catfish
Provedor de dados: 16
Autores: Boeseman, M.
Two large specimens of a hitherto unknown species of neotropical catfish have recently been found dead and washed ashore beneath the dike along the Westerscheldt near Biezelinge, Zeeland, at a mutual distance of approximately 300 meters. Both were in excellent condition and have been presented to the Rijksmuseum van Natuurlijke Historie at Leiden by Mr. B. J. J. R. Walrecht. A superficial examination already disclosed the fact that the two specimens belong to the (sub)genus Selenaspis, a well known group of catfishes inhabiting the salt and brackish shores and estuaries of the northern part of the South American continent. Some of the species are known to spawn in fresh water. The present specimens must have been transported by ship. Whether they have been...

Note on the Characid genus Brachychalcinus Boulenger (1892), including the description of a new species
Provedor de dados: 16
Autores: Boeseman, M.
In a previous paper (1952, p. 190) I reported upon a specimen from the Lucie River, Surinam, doubtlessly belonging to Boulenger's genus Brachychalcinus, but had to abstain from giving a definite specific identification on account of the lack of comparative material, the insufficiency of previous literature, and the obviously juvenile state of the single specimen. A possibility to look once more into this matter, and to amend my previous statement, was brought about by the existence of eight specimens from the same river system, and probably belonging to the same species, in the collections of the Chicago Natural History Museum, and the offer to have these sent to me as a loan. For this courtesy, and for the loan of a single juvenile specimen of...

Provedor de dados: 16
Autores: Bath, H.; Wirtz, P.
During the Tyro Mauritania Expedition (1988) of the Nationaal Natuurhistorisch Museum (formerly Rijksmuseum van Natuurlijke Historie) Leiden, six species of Blenniidae were caught at the coast and on the shelf of Mauritania, off the Banc d'Arguin. Additional specimens of Spaniblennius riodourensis (Metzelaar, 1919), previously known only from the holotype, allow to more fully describe the species and the genus Spaniblennius Bath &amp; Wirtz, 1989. New records of Parablennius pilicornis (Cuvier, 1829), Parablennius goreensis (Valenciennes, 1836), Lipophrys velifer (Norman, 1935), Lipophrys pholis (Linnaeus, 1758), and Blennius normani Poll, 1949, present extensions of the known ranges of these species.

De Harders Chelon labrosus en Liza ramada bij 't Horntje—Texel
Provedor de dados: 16
Autores: Boer, P.
INLEIDING In 1970 werd gekonstateerd dat Liza ramada (Risso, 1826) (Mugil ramada) een zeldzame soort is en dat de vis die men voor L. ramada hield in werkelijkheid Chelon labrosus (Risso, 1826) (Mugil labrosus) blijkt te zijn (Boer, 1971). Chelon labrosus is dus de algemene soort, Liza ramada de zeldzame, die tot 1970 — althans in Nederland — alleen in zoet water werd aangetroffen. In 1971 werd het onderzoek naar harders voortgezet. Hiertoe werden bijna alle harders onderzocht die werden gevangen in de fuiken van het N.I.O.Z. bij 't Horntje (zuidpunt Texel). Uit dit onderzoek, dat van eind maart tot begin september 1971 plaatsvond, bleek dat Liza ramada niet zeldzaam is: 5% van de onderzochte harders behoort tot deze soort.

Frederik Petrus Koumans, 1905-1977, a biography and a tentative list of his biological papers
Provedor de dados: 16
Autores: Boeseman, M.
On Wednesday 27 April 1977, my predecessor as a curator of fishes at the Leiden Museum, Dr. F. P. Koumans, after a short illness, rather unexpectedly passed away at the age of 72. Considering his rôle as a staff member of the Museum and the importance of his contributions to science, the publication of a short biographical note and a list of his publications seems an obligation towards his former colleagues, if not a duty for me as his former pupil. Frederik Petrus Koumans was born on 21 January 1905 in the Hague, where he attended elementary and high school. After his high school examination in 1922, he studied biology at the nearby University of Leiden, where he obtained his masters degree in 1927, and his doctorate in 1931. There is no information...

List of egg-capsules of Rajidae washed ashore in the Netherlands
Provedor de dados: 16
Autores: Lacourt, A.W.
Egg-capsules of the following four Raja-species have been known with certainty for many years from the shores of the Netherlands: Raja clavata Linnaeus, Raja montagui Fowler (Raja maculata Montagu), Raja radiata Donovan, and Raja batis Linnaeus. It is therefore of interest to note that from 1931 to 1935 and in 1936 egg-capsules diverging strongly from the well-known species, have been found on the beach between Wassenaar and Noordwijk (in the province of South-Holland). These capsules appeared to belong to the following five species: Raja brachyura Lafont, Raja naevus Müller and Henle, Raja undulata Lacépède, Raja microcellata Montagu, and Raja marginata Lacépède. The determinations have been made with Clark's (1922) paper, with the exception of Raja...

Professor I. Q. van Regteren Altena was zoo vriendelijk mij een aantal teekeningen ter beschikking te stellen, die eens aan het huis Plantijn moeten toebehoord hebben. Immers, sommige daarvan hebben gediend als voorbeeld voor houtsneden in den Herbarius von Dodonaeus van 1618, gedrukt „t'Antwerpen in de Plantynsche Druckerye van Balthasar Moretus" (zie Engel, in: Ned. Kruidk. Arch. 53, 1943, p. 46-55). Wanneer men de fraaie teekeningen vergelijkt met de reproducties in het Cruydtboeck, is het opvallend, dat de teekeningen losser, zwieriger en natuurlijker zijn, terwijl de houtsneden allerlei wijzigingen vertoonen, die klaarblijkelijk aangebracht werden ten einde de figuur in het formaat van het houtblok te doen passen.

Provedor de dados: 16
Autores: Goren, M.; Karplus, I.
INTRODUCTION The genus Fowleria Jordan &amp; Evermann, 1903 is represented in the Red Sea by four species: F. aurita (Valenciennes, 1831) (the type species); F. variegata (Cuvier &amp; Valenciennes, 1832); F. isostigma (Jordan &amp; Seale, 1905) and F. marmorata (Alleyn &amp; Mecleay, 1876). All of them are very similar to each other in their meristic counts and body proportions, but differ from each other in specific colour patterns. In the course of research of animals living within branched corals in the Red Sea, a new species of Fowleria was found. The new species, F. abocellata, was compared with the other congeneric species (Red Sea material) and found to have a unique colour pattern which enabled this species to be easily distinguished from all the...

INTRODUCTION The present paper forms the continuation of a series pretending to cover at least most of the Surinam representatives of loricariid armoured catfishes (for earlier papers, see Boeseman, 1968, 1969, 1971, and 1974), but for various reasons it is less extensive in scope than its forerunners. The main reasons are that, (1) it seems unnecessary to repeat the general information provided in the earlier papers, especially since the employed methods, the provided measurements (see fig. 1), and the localities (fig. 2) or habitats are the same, or at least similar (exceptions: measurements and counts up to "caudal base" in fact are up to the end of the last, small scute of the lateral series, while in some of tables, to the total (or axial) length, the...

At the end of November 1960, the Leiden Museum received an interesting collection of animals, mostly fishes, from the Niger delta. All specimens were collected by Mr. H. J. G. Beets, at the time employed by Shell B.P. — Delta Investigations, during the period May to August 1960, and in the region between Port Harcourt and Brass. Unfortunately, owing to lack of time, the separate specimens or lots were not labelled, but the collecting localities are limited in number and restricted to only the eastern part of the delta. The fish collection, consisting of 130 specimens, proved to belong to 51 species, some of which gave occasion for a reexamination and comparison of Bleeker and Steindachner types in the Leiden Museum collection.
