Abstract The karyotype of Amphisbaena ridleyi, an endemic species of the archipelago of Fernando de Noronha, in State of Pernambuco, Brazil, is described after conventional staining, Ag-NOR impregnation and fluorescence in situ hybrid- ization (FISH) with a telomeric probe. The diploid number is 46, with nine pairs of macrochromosomes (three metacentrics, four subtelocentrics and two acrocentrics) and 14 pairs of microchromosomes. The Ag-NOR is located in the telomeric region of the long arm of metacentric chromosome 2 and FISH revealed signals only in the telomeric region of all chromosomes. Further cytogenetic data on other amphisbaenians as well as a robust phylogenetic hy- pothesis of this clade is needed in order to understand the evolutionary changes on amphisbaenian karyotypes. Key words: Amphisbaena ridleyi, karyotype, Fernando de Noronha, Ag-NOR, FISH with telomeric probes. -

Barroso1 Amphibians are models for studying applied ecological issues such as habitat loss, pollution, disease, and global climate change due to their sensitivity and vulnerability to changes in the environment. Developmental series of amphibians are informative about their biology, and X-ray based 3D reconstruction holds promise for quantifying morphological changes during growth—some with a direct impact on the possibility of an experimental investigation on several of the ecological topics listed above. However, 3D resolution and discrimination of their soft tissues have been difcult with traditional X-ray computed tomography, without time-consuming contrast staining. Tomographic data were initially performed (pre-processing and reconstruction) using the open- source software tool SYRMEP Tomo Project. Data processing and analysis of the reconstructed tomography volumes were conducted using the segmentation semi-automatic settings of the software Avizo Fire 8, which provide information about each investigated tissues, organs or bone elements. Hence, volumetric analyses were carried out to quantify the development of structures in diferent tadpole developmental stages. Our work shows that synchrotron X-ray microtomography using phase-contrast mode resolves the edges of the internal tissues (as well as overall tadpole morphology), facilitating the segmentation of the investigated tissues. Reconstruction algorithms and segmentation software played an important role in the qualitative and quantitative analysis of each target structure of the Thoropa miliaris tadpole at diferent stages of development, providing information on volume, shape and length. -
Biogeography of the Reptiles of the Central African Republic

Rasmussen, Curator of Reptiles at the Zoological Museum of Copenhagen, Denmark Abstract.—A large number of reptiles from the Central African Republic (CAR) were collected during recent surveys conducted over six years (October 1990 to June 1996) and deposited at the Paris Natural History Museum (MNHN). This large collection of 4873 specimens comprises 86 terrapins and tortois- es, five crocodiles, 1814 lizards, 38 amphisbaenids and 2930 snakes, totalling 183 species from 78 local- ities within the CAR. A total of 62 taxa were recorded for the first time in the CAR, the occurrence of numerous others was confirmed, and the known distribution of several taxa is greatly extended. Based on this material and an additional six species known to occur in, or immediately adjacent to, the coun- try from other sources, we present a biogeographical analysis of the 189 species of reptiles in the CAR. Key words.—Central African Republic, reptile fauna, biogeography, distribution. he majority of African countries have been improved; known distributions of many species Tthe subject of several reptile studies (see are greatly expanded and distributions of some for example LeBreton 1999 for Cameroon). species are questioned in light of our results. -
Early German Herpetological Observations and Explorations in Southern Africa, with Special Reference to the Zoological Museum of Berlin
Bonner zoologische Beiträge Band 52 (2003) Heft 3/4 Seiten 193–214 Bonn, November 2004 Early German Herpetological Observations and Explorations in Southern Africa, With Special Reference to the Zoological Museum of Berlin Aaron M. BAUER Department of Biology, Villanova University, Villanova, Pennsylvania, USA Abstract. The earliest herpetological records made by Germans in southern Africa were casual observations of common species around Cape Town made by employees of the Dutch East India Company (VOC) during the mid- to late Seven- teenth Century. Most of these records were merely brief descriptions or lists of common names, but detailed illustrations of many reptiles were executed by two German illustrators in the employ of the VOC, Heinrich CLAUDIUS and Johannes SCHUMACHER. CLAUDIUS, who accompanied Simon VAN DER STEL to Namaqualand in 1685, left an especially impor- tant body of herpetological illustrations which are here listed and identified to species. One of the last Germans to work for the Dutch in South Africa was Martin Hinrich Carl LICHTENSTEIN who served as a physician and tutor to the last Dutch governor of the Cape from 1802 to 1806. Although he did not collect any herpetological specimens himself, LICHTENSTEIN, who became the director of the Zoological Museum in Berlin in 1813, influenced many subsequent workers to undertake employment and/or expeditions in southern Africa. Among the early collectors were Karl BERGIUS and Ludwig KREBS. Both collected material that is still extant in the Berlin collection today, including a small number of reptile types. Because of LICHTENSTEIN’S emphasis on specimens as items for sale to other museums rather than as subjects for study, many species first collected by KREBS were only described much later on the basis of material ob- tained by other, mostly British, collectors. -

In 2009, during the participation of a scientific congress in Chetumal (Quintana Roo, Mexico), Gunther Köhler went for a night cruise by car with Pablo M. Beutelspacher-García and was surprised by the many road-killed snakes they encountered. This prompted the authors to start a long-term project with nocturnal snake surveys at 15-day intervals along a 39 km road transect. Since they started the project in early 2010, the authors have encountered a total of 578 snakes (433 road-killed, 145 alive) along the study transect, representing 31 species. Pictured here is a road-killed individual of Drymarchon melanurus.

Ctenosaura Defensor (Cope, 1866)
Ctenosaura defensor (Cope, 1866). The Yucatecan Spiny-tailed Iguana, a regional endemic in the Mexican Yucatan Peninsula, is distributed in the Tabascan Plains and Marshes, Karstic Hills and Plains of Campeche, and Yucatecan Karstic Plains regions in the states of Campeche, Quintana Roo, and Yucatán (Lee, 1996; Calderón-Mandujano and Mora-Tembre, 2004), at elevations from near “sea level to 100 m” (Köhler, 2008). In the original description by Cope (1866), the type locality was given as “Yucatán,” but Smith and Taylor (1950: 352) restricted it to “Chichén Itzá, Yucatán, Mexico.” This lizard has been reported to live on trees with hollow limbs, into which they retreat when approached (Lee, 1996), and individuals also can be found in holes in limestone rocks (Köhler, 2002). Lee (1996: 204) indicated that this species lives “mainly in the xeric thorn forests of the northwestern portion of the Yucatán Peninsula, although they are also found in the tropical evergreen forests of northern Campeche.” This colorful individual was found in low thorn forest 5 km N of Sinanché, in the municipality of Sinanché, in northern coastal Yucatán. Wilson et al. (2013a) determined its EVS as 15, placing it in the lower portion of the high vulnerability category. Its conservation status has been assessed as Vulnerable by the IUCN, and as endangered (P) by SEMARNAT. ' © Javier A.

NATIONAL MUSEUM Vol. 91 Washington : 1941 No. 3128 REPORT ON THE SMITHSONIAN-FIRESTONE EXPEDI- TION'S COLLECTION OF REPTILES AND AMPHIBIANS FROM LIBERIA By Arthur Loveridge Dr. William M. Mann, director of the National Zoological Park in Washington and leader of the Smithsonian-Firestone Expedition, 1940, is to be congratulated on finding time to assemble a representa- tive collection of the Liberian herpetofauna, despite the exacting duties involved in the capture and care of wild creatures, the securing of which was the primary purpose of his journey. This coUection, consisting as it does of over 500 specimens repre- senting 56 species, naturally adds considerably to our knowledge of the lower vertebrates of the country whose fauna is so imperfectly known as that of the Liberian Republic. Among the results of a study of this material, therefore, the following species have had to be described as new Typhlops manni, new species from Harbel. Hylamlatcs cochranae, new species from Bendaja. Leptopelis Icquaerti, new species from Gbanga, Gibi, etc. Rana albolabris parkeriana, new name for acutirostris Parlier, preoccupied. (This is the Angolan race of the typical form occurring in Liberia.) In addition we are able to add the undermentioned to the steadily growing list of species to be found within the boundaries of the Republic Boaedon Uneatus lineatus. Rana longirostris.
