Despite an encounter with a large rattlesnake, the pair ultimately scrambled into the canyon and up the other side. Wider head, larger eyes, smaller feet, and a weaker development of the margins along the dorsal stripe. Historical versus Current Distribution. In: Steinhoff, Harold W.; Ives, Jack D., eds.
