Coral snakes in North America are most notable for their red, yellow/white, and black colored banding. However, several nonvenomous species have similar (though not identical) coloration, including the scarlet snake, genus "Cemophora"; some of the kingsnakes, and the milk snakes, genus "Lampropeltis", whose banding however does not include any red touching any yellow; also, there is a genus of shovelnose snake, genus "Chionactis", whose color banding actually matches that of a genuine coral snake. No genuine coral snakes in North America, however, exhibit red bands of color in contact with bands of black. So while on extremely rare occasions a certain non-venomous snake might be mistaken for a coral snake, the mnemonic holds true in that a red/ yellow/ black banded snake in North America whose red banding is in contact with its black banding is never a venomous coral snake.
