Rhamnophis
''Rhamnophis'' is a genus of arboreal venomous snakes, commonly known as dagger-tooth tree snakes or large-eyed tree snakes, in the family Colubridae. The genus is endemic to equatorial sub-Saharan Africa. There are two recognized species. Taxonomy The status of the genus ''Rhamnophis'' has long been subject to debate, and has been treated as a synonym of ''Thrasops'' by some authors. Both genera belong to the tribe Dispholidini, and are closely related to the genera ''Dispholidus'', '' Thelotornis'', and ''Xyelodontophis''. Species The following two species are recognized as being valid. www.reptile-database.org. *''Rhamnophis aethiopissa'' Günther, 1862 – large-eyed green tree snake, splendid dagger-tooth tree snake *''Rhamnophis batesii'' ( Boulenger, 1908) – spotted dagger-tooth tree snake Venom ''Rhamnophis'' are rear-fanged colubrids; that is to say, they have venom, which they may be able to inoculate by biting.

Boomslang
The boomslang (, , or ; ''Dispholidus typus'') is a large, highly venomous snake in the family Colubridae. Taxonomy and etymology Its common name means "tree snake" in Afrikaans and Dutch – ''boom'' meaning "tree", and ''slang'' meaning "snake". In Afrikaans, the name is pronounced . The boomslang is thought to be closely related to members of the genera '' Thelotornis'', ''Thrasops'', ''Rhamnophis'', and ''Xyelodontophis'', with which it forms the taxonomic tribe Dispholidini. Subspecies Two subspecies are recognized, including the nominotypical subspecies. * ''D. t. kivuensis'' * ''D. t. typus'' The trinomial authority in parentheses for ''D. t. typus'' indicates that the subspecies was originally described in a genus other than ''Dispholidus''. Description The average adult boomslang is in total length. Some exceed . The eyes are exceptionally large, and the head has a characteristic egg-like shape. Coloration is highly variable.

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.

Opisthoglyphous
A snake skeleton consists primarily of the skull, vertebrae, and ribs, with only vestigial remnants of the limbs. Skull The skull of a snake is a very complex structure, with numerous joints to allow the snake to swallow prey far larger than its head. The typical snake skull has a solidly ossified braincase, with the separate frontal bones and the united parietal bones extending downward to the basisphenoid, which is large and extends forward into a rostrum extending to the ethmoidal region. The nose is less ossified, and the paired nasal bones are often attached only at their base. The occipital condyle is either trilobate and formed by the basioccipital and the exoccipitals, or a simple knob formed by the basioccipital; the supraoccipital is excluded from the foramen magnum. The basioccipital may bear a curved ventral process or hypapophysis in the vipers. The prefrontal bone is situated, on each side, between the frontal bone and the maxilla, and may or may not be in co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...
