From Wikipedia:
A rather small rattlesnake with all subspecies measuring 30–60 cm in length. Color patterns are generally a dark brown base with pale or white horizontal striping, but vary slightly between subspecies. The distinctive ridges along each side of its nose, which are a series of upturned scales, are unique to its species and are the origin of its name.

Crotalidae -- Rattlesnake Family
