Ptyas


Ptyas is a genus of colubrid snakes. This genus is one of several colubrid genera colloquially called "rat snakes" or "ratsnakes".
The generic name derives from Ancient Greek πτυάς, meaning "spitter", which referred to a kind of snake believed to spit venom in the eyes of humans, although in reality none of the Ptyas are known to spit venom.
