Four species of the genus Lampropeltis are in northeast Mississippi, including the common kingsnake, the prairie kingsnake and the milk snake, which is similar to the venomous coral snake. The scarlet snake (Cemophora coccinea) is another coral-like nonvenomous species, and the only species in this genus.
Two species of small earth snakes live in northeast Mississippi: the rough earth snake (V. striatula) and the smooth earth snake (V. valeriae). The mud snake (Farancia abacura) and the colorful rainbow snake (Farancia erytrogramma) are very secretive, but also seen in Mississippi. Storeia snakes include the brown snake (S.dekayi) and the redbelly snake (S. occipitomaculata). These are all nonvenomous species.

The black pine snake (Pituophis melonoleucus lodingi) can grow up to 8 feet long and also lives in the area.
Agkistrodon, Crotalus, Sistrurus and Micrurus are the only venomous snakes found across Mississippi. Agkistrodon include the eastern and the western cottonmouths, as well as the southern copperhead. Ratllesnakes are members of the genera Crotalus and Sistrurus, including the timber rattlesnake (C. horridus), the eastern diamondback rattlesnake (C. adamanteus), the dusky pygmy rattlesnake (S.miliarius barbouri), the Carolina pygmy rattlesnake (S. miliarius miliarius) and the western pygmy rattlesnake (S.miliarius streckeri).
