Appearance
The background dorsal color is pinkish-tan to light gray or cream. Ten to 18 relatively large and regularly-shaped brown to slate-gray dorsal blotches or saddles are on the body, with 2-4 on the tail. These blotches do not reach the ventrals. Some individuals have smaller, lateral dark blotches, but most do not. The dark dorsal blotches usually have dark edges. Lighter areas between the blotches have diffuse dark speckling. A dark band crosses over the top of the head and through the eyes, angling back to the corners of the mouth. The ventral surface is immaculate white.References:
