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.

Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884).

Afrânio Pompílio Gastos Do Amaral
Afrânio Pompílio Gastos do Amaral (1 December 1894 in Belém – 29 November 1982 in São Paulo) was a Brazilian herpetologist. As a youngster, he collected snakes for Augusto Emilio Goeldi (1859-1917). He studied medicine in Salvador, Bahia, later finding employment at the Instituto Butantan in São Paulo. Here, his work involved research and production of anti-venom serum. In 1921 he succeeded Vital Brazil (1865-1950) as director of the Instituto Butantan. During his career, he was the author of over 450 published works.Paragraph based on translated text of an equivalent article at the French Wikipedia; source listed as: Kraig Adler (1989).
