ringneck snake

Diadophis punctatus regalis, commonly known as the regal ringneck snake, is a subspecies of ringneck snake endemic to the southwestern United States and northern Mexico.

The regal ringneck snake is typically gray in color, with a dark-speckled white or cream underside, which becomes bright red or orange near and under the tail. It is distinguished by a yellow to orange ring around its neck which is typically bordered with black. However, the neck ring is frequently absent in this subspecies. The belly color extends onto one or more dorsal scale rows. They are among the larger of the ringneck snake subspecies, growing from 8 to 34 inches (20 to 87 cm) long. Their scales are smooth.-Wikipedia
