Distribution. — This little lizard is a mountain-dwelling 

 species throughout its range in California, which ex- 

 tends the whole length of the State. It is very abun- 

 dant in Hemet and Strawberry Valleys, in the San 

 Jacinto Mountains of Riverside County, but has not 

 been reported from any of the more northern coast 

 ranges."^ On the western slope of the Sierra Nevada 

 the Mountain Lizard has been found from Kern River 

 north to Mount Shasta. It is common on the eastern 

 slope of these mountains opposite Mono and Owen's 

 Lakes and has been secured also in the Panamint 

 Mountains. In the southern Sierra Nevada its vertical 

 range extends from about 5,500 to nearly 9,000 feet above 

 the level of the sea. 



It has been taken in Nevada (Juniper Mts., Mt. Ma- 

 gruder), western Utah, southern Idaho (Blackfoot, Big 

 Lost River, Lemhi Agency, and along Snake River from 

 Pocatello to Weiser), Washington (Puget Sound, Cowlitz 

 County), and Oregon (Dalles, Summer Lake, Grant's, 

 Umatilla, etc.). In the north it is not restricted to the 

 mountains.
