Carphophis

Carphophis (common name worm snakes) is a genus of small colubrid snakes endemic to the United States. The genus consists of two species, one of which has two subspecies.

==Description== Worm snakes are small snakes, 35 cm (14 in) or less in total length (including tail). The males are shorter than the females. Both sexes are usually a dark brown in color on the upperside, with a lighter-colored, pink or orange underside. Both species are cylindrical and unpatterned, with a pointed head and small black eyes. They are easily mistaken for other similar species, such as the earth snakes (genus Virginia) and the brown snakes (genus Storeria). Worm snakes have narrow heads, sharp tail tips, and are not venomous.
