Colubrids

Milk Snake The milk snake or milksnake (Lampropeltis triangulum ), is a species of kingsnake; up to 24 subspecies are sometimes recognized. Lampropeltis elapsoides , the scarlet kingsnake, was formerly classified as a 25th subspecies (L. t. elapsoides ), but is now recognized as a distinct species.[2] The subspecies have strikingly different appearances, and many of them have their own common names. Some authorities suggest that this species could be split into several separate species.[2] They are not venomous to humans.[3][4] Hognose Snake Hognose snake is a common name for several unrelated species of snakes with upturned snouts, classified in two colubrid snake families and one pseudoxyrhophiid snake family. They include the following genera: Corn Snake The corn snake (Pantherophis guttatus ), sometimes called red rat snake [4] is a species of North American rat snake in the family Colubridae. The species subdues its small prey by constriction.[5][6] It is found throughout the southeastern and central United States. Though superficially resembling the venomous copperhead (Agkistrodon contortrix ) and often killed as a result of this mistaken identity, the corn snake lacks functional venom and is harmless. The corn snake is beneficial to humans[7] because it helps to control populations of wild rodent pests that damage crops and spread disease.[8] * Coluber guttatus Linnaeus, 1766
