cured also in Mono (Benton), Kern (Walker Basin), Shasta 
(Baird, Canoe Creek), and Siskiyou (Gazelle) counties. 
Habits—These snakes usually are found in sagebrush. 
They move with great swiftness either on the ground or in 
the bushes. When secured they sometimes fight vigorously, 
coiling themselves about the limbs of the bushes, biting, and 
resisting capture to the utmost (Taylor). The stomach of 
one specimen contained an adult Cnemidophorus tigris 
(Ruthven & Gaige).
