''Platyceps ladacensis'', the braid snake or Jan's cliff racer, is a species of snake of the family Colubridae Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on ever .... The snake is found in Asia.

John Anderson (zoologist)
John Anderson (4 October 1833 – 15 August 1900) was a Scottish anatomist and zoologist who worked in India as the curator of the Indian Museum, Calcutta. Early life Anderson was born in Edinburgh, the second son of Thomas Anderson, who worked in the National Bank of Scotland, and his wife Jane Cleghorn. He took an interest in natural history at an early age as did his brother Thomas Anderson, who worked at the Royal Botanic Garden in Calcutta from 1861 to 1863. He went to school at George Square Academy and Hill Street Institution before joining work at the Bank of Scotland. He left the bank to study medicine, and graduated from the University of Edinburgh in 1861. He studied anatomy under John Goodsir and received his MD in 1862 with a gold medal for his thesis in zoology. He was also associated with the founding of the Royal Physical Society which grew out of the Wernerian Society over which he presided. He was appointed to the chair of natural history in the Free C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Species Distribution
Species distribution —or species dispersion — is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the following qualities: * Sometimes a distinction is made betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platyceps
''Platyceps'' is a genus of snakes of the family Colubridae endemic to Eurasia. Taxonomy The genus was erected in 1860 by Edward Blyth, allying species previously described. The genus name ''Platyceps'' was inadvertently used for a fossil species in 1877, now recognised as ''Platycepsion wilkinsoni''. Species The following 30 species are recognized as being valid. *''Platyceps afarensis'' Schätti & Ineich, 2004 *''Platyceps atayevi'' ( Tuniyev & Shammakov, 1993) *''Platyceps bholanathi'' (Sharma, 1976) *''Platyceps brevis'' (Boulenger, 1895) *''Platyceps collaris'' ( F. Müller, 1878) *''Platyceps elegantissimus'' ( Günther, 1878) *''Platyceps florulentus'' ( I.

Reptiles Described In 1871
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...
