Xenotyphlops
''Xenotyphlops'' is a genus of snakes, the only genus of the family Xenotyphlopidae, comprising two species found only in Madagascar. These snakes are also known as the Malagasy blind snake. Physical characteristics The family Xenotyphlopidae is composed of small blind snakes. These members lack cranial infrared receptors in pits or durface indentations. It is thought that these snakes used to have eyes but lost use of them over time. Members of the genus ''Xenotyphlops'' are distinguishable externally from the Typhlopidae by possessing a greatly enlarged and nearly circular rostral shield and a single enlarged anal shield. This shield is nearly vertical in a lateral aspect; as a result, the two species have a "bulldozer" appearance. ''Xenotyphlops'' get no larger than an earthworm and have translucent pink scales. ''Xenotyphlops'' species are internally unique in that they lack a tracheal lung and possess an unexpanded tracheal membrane. Like many other snake families they are ...

Xenotyphlops Grandidieri
''Xenotyphlops grandidieri'' is a species of blind snake endemic to Madagascar. No subspecies are currently recognized. Taxonomy In addition to having no subspecies, ''X. grandidieri'' is the only species in the genus ''Xenotyphlops'', which is the only genus in the family Xenotyphlopidae. Therefore, ''X. grandidieri'' is a monotypic species in a monotypic genus in a monotypic family.Wegener et al. 2013. Etymology The specific name, ''grandidieri'', is in honor of French naturalist Alfred Grandidier.Beolens B, Watkins M, Grayson M (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Xenotyphlops grandidieri'', p. 105). Geographic range ''Xenotyphlops grandidieri'' is found in northern Madagascar. For over 100 years ''X. grandidieri'' was known only from the type specimens and the vague type locality "Madagascar". References Further reading * Mocquard F (1905).

François Mocquard
François Mocquard (27 October 1834 – 19 March 1917) was a French herpetologist born in Leffond, Haute-Saône. In 1860 he was named ''préparateur du physique'' after receiving his Bachelor of Science degree at the Faculty of Besançon. Subsequently, he earned degrees in physical sciences (1862), mathematical sciences (1865) and medicine (1873). Despite being middle-aged, he made a career change, and began studying natural sciences in the laboratory of Alphonse Milne-Edwards (1835-1900) at the Muséum national d'histoire naturelle in Paris. In 1884 he earned his doctorate of sciences with a thesis on the structure of the stomach in crustaceans, afterwards working as an assistant in the ichthyology and herpetology department at the museum. During his career he described numerous herpetological taxa, most notably species from Madagascar, Tonkin, Borneo, Mexico and Central America. In addition, he has several species named after him, including reptiles, '' Alluaudina mocquardi'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French naturalist and explorer. From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey. They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest. The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet, but was prevented by a severe attack of fever. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhlopidae
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands. The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. Typhlopids do not have dislocatable lower jaw articulations restricting them to prey smaller than their oral aperture. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, 18 genera are recognized containing over 200 species. Geographic range They are found in most tropical and many subtropical regions all over the world, particularly in Africa, Asia, islands in the Pacific, tropical America, and southeastern Europe. Fossil record Possible Typhlopid skin has been identified in Dominican amber. Genera Type genus Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van Wallach
Van Stanley Bartholomew Wallach (born 1947) is an American herpetologist and an expert on blindsnakes and on the systematics, internal anatomy, and taxonomy of snakes. He has contributed to the descriptions of at least 46 species of snakes and has conducted fieldwork on tropical snakes in the Philippines, Nicaragua, and the Democratic Republic of the Congo. For many years Wallach worked as a Curatorial Assistant at the Museum of Comparative Zoology at Harvard University in Cambridge, Massachusetts. He retired from the museum in 2012, but he continues to work on snake taxonomy. Wallach was the lead editor of the 1,227 page authoritative reference book ''Snakes of the World''. In the 2000s Wallach was one of several herpetologists who became embroiled in a dispute with Raymond Hoser, a self-published Australian herpetologist, over proper nomenclatorial acts. Hoser charged Wallach with attempting to name species that Hoser had already described in his self-published journal. Wallach' ...

Herpetology
Herpetology (from Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is the branch of zoology concerned with the study of amphibians (including frogs, toads, salamanders, newts, and caecilians (gymnophiona)) and reptiles (including snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians, and the tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the scientific study of birds is the subject of ornithology. Thus, the definition of herpetology can be more precisely stated as the study of ectothermic (cold-blooded) tetrapods. Under this definition "herps" (or sometimes "herptiles" or "herpetofauna") exclude fish, but it is not uncommon for herpetological and ichthyological scientific societies to collaborate. Examples include publishing joint journals and holding conferences in order to foster the exchange of ideas between the fields, as the American Society of Ichthyologists and He ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
