Yosemite road four miles from Wawona, and between 

 Groveland and Crocker's. Farther north they have been 

 found at Big Trees, Calaveras County, and at Sugar Loaf 

 (5,000 feet), El Dorado County. Grinnell has recorded 

 it from an altitude of 2,000 feet in the Lower Santa Ana 

 Canyon, in San Bernardino County. I have seen red-headed 

 specimens from Fresno, the Sequoia National Park in Tulare 

 County, Fort Tejon and the Tehachapi mountains in Kern 

 County, and Campo, San Diego County, California, and 

 Levan, Juab County, Utah. 



Habits. This lizard is common in the mountains near 

 the Yosemite Valley and is well known to the hotel-keepers 

 and ranch men. It is often seen in grass and among rocks, 

 retreating swiftly to holes under stones and boulders when 

 frightened.
