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. The attention was again attracted to it by TAYLOR (1922, p. 65) who (1918, p. 237) described a new species, H. insularis, from the... |

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... |

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. |

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... |

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... |

Two new species of Pseudogonatodes Ruthven, 1915, are described, one from the Rio Juruá Basin, in the state of Acre, Brazil (Amazonian rainforest), the other from Rancho Grande, in the state Aragua, Venezuela (cloud forest). Both have granular dorsals and relatively numerous fourth toe lamellae, of which the third (from tip to base of toe) is not distinctly larger than the two distal ones. The species from the Rio Juruá is small, with dark belly, and recognised, among other characteristics, by its tall, conical to flat-conical dorsals. That from Rancho Grande is relatively large, with low number of ventrals, and mental with a straight or convex posterior segment medially, among other distinctive characteristics. Some remarks on the geographic distribution... |

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,... |

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.... |

Der von SPIX im Jahre 1825 in „Species novae Lacertarum" auf Seite 17 beschriebene und auf Tafel 18 Fig. 2 abgebildete Thecadactylus pollicaris wurde von CUVIER „Règne animal II" Seite 54 in die Synonymie von G(ecko) mabuia (= Hemidactylus mabouia MOR.) versetzt und die meisten späteren Autoren schlossen sich dieser Ansicht an. DUMÉRIL und BIBRON führen in Band III ihrer „Erpétologie générale" S. 362 die Spixsche Art allerdings nur mit einem Fragezeichen in der Synonymie von Hemidactylus mabouia auf und auch GRAY „ Catalogue of Lizards" S. 154 folgt ihrem Beispiel. Aber seitdem PETERS, der die Spixschen EidechsenArten einer Revision unterzog (Monatsber. Akad. Berlin 1877), Thecadactylus pollicaris SPIX in die Synonymie von Hemidactylus tuberculosus RADDI... |

Im Vergleich zu der Reptilien-Ausbeute Kopstein's (1926, S. 71) sind die von ihm auf den Molukken und einigen benachbarten Eilanden während der Jahre 1922/24 zusammengebrachten Amphibien naturgemäss wesentlich artenärmer. Durch mehrere bemerkenswerte Neunachweise und zwei fiir die Wissenschaft neue Formen verdient aber diese kleine Sammlung, die sich aus 10 Arten zusammensetzt, dennoch ein recht erhebliches Interesse. Ich erhielt das Material, das sich im 'sRijks Museum van Natuurlijke Historie in Leiden befindet, von dem Direktor dieses Museum, Herrn Prof. Dr. E. D. van Oort zur Bearbeitung, dem ich dafür auch hier meinen ergebensten Dank zum Ausdruck bringe. Eine ganze Reihe von Exemplaren hat allem Anschein nach schon Herrn Prof. Dr. P. N. van Eampen... |

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... |

Triadobatrachus massinoti is a batrachian known from a single fossil from the Early Triassic of Madagascar that presents a combination of apomorphic salientian and plesiomorphic batrachian characters. Herein we offer a revised description of the specimen based on X-ray micro-tomography data. We report previously unknown caudal vertebrae, possible mentomeckelians, and hidden parts of other structures. We also confirm the presence of a ventrolateral ledge on the opisthotic, and we rectify some previous interpretations. There are no cervical ribs and the jaw may have had an angular. The presacral region is composed of 15 vertebrae with a unique atlas-axis complex instead of 14 vertebrae with a bipartite atlas. The configuration of the pelvic girdle is not... |

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. The material examined by me consists of 110 specimens from the collections of the Rijksmuseum van Natuurlijke Historie, Leiden (67... |

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... |

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... |

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... |

Pseudothecadactylus nom. nov. In this journal I (Brongersma, 1934, p. 176) described a new genus of gekkonid lizards under the name Torresia. As Dr H. A. Longman, Brisbane, kindly pointed out to me this name is preoccupied by Torresia Castelnau, 1875 (cf. D. S. Jordan, The Genera of Fishes, part III, 1919, p. 378). The genus of gekkonid lizards may now be named: Pseudothecadactylus, type of genus: Thecadactylus australis Gthr., 1877. For the description I may refer to my previous paper on this subject. Dendroaspis Schlegel In recent literature on African herpetology it is usual to give the name Dendraspis Schlegel to a genus of snakes of which Elaps jamesoni Traill, 1843, is the type. Schlegel (1848?, p. 5), however, gave the name Dendroaspis to this... |
