18. CNEMIDOPHORUS 5J_3 



County, Ajo, Pima County, and Papago Wells, Yuma 

 County. To the eastward of these localities it seems to be 

 replaced by its very close relative C. melanostethus. 



In Nevada, this subspecies has been found in Lincoln 

 (Pahranagat Valley, Desert Valley, Meadow Creek Valley, 

 Caliente), Clark (Bend of the Colorado, valleys of the 

 Virgin and Muddy rivers, Vegas Valley, St. Thomas, Las 

 Vegas, Pahrump Valley, Callville), Nye (Amargosa Valley, 

 Rhyolite, Tonopah, Oasis Valley, Pahrump Valley), Esmer- 

 alda (Goldfield), Ormsby (Carson City), Washoe (between 

 Reno and Pyramid Lake, Pyramid Lake, Wadsworth), 

 Humboldt (Winnemucca, Golconda, Thousand Creek, Pine 

 Forest Mountains), Eureka (Palisade), and Elko (Carlin), 

 counties. 



In Idaho, it has been collected in Twin Falls (between 

 Shoshone Falls and Twin Falls, Upper Salmon Falls), 

 Cassia (Conant), Gooding (Bliss), Elmore (Glenn's Ferry), 

 Ada (Boise), and Payette (Payette), counties. 



In Oregon, this lizard has been secured three miles 

 northeast of Huntington, Baker County. 



Utah records are Washington (Lower Santa Clara Val- 

 ley, Upper Santa Clara Crossing, Leeds, Virgin City, Belle- 

 vue, six miles north of Washington, St. George, Rockville 

 between Rockville and Springdale), Iron (Rush Lake), Bea- 

 ver (Beaver Creek at 6,000 feet, Newhouse), Millard (seven 

 miles south of Kanosh), Emery (Green River), Grand 

 (Thompson), Davis (Clearfield), and Salt Lake (Fort 

 Douglas) counties. 



I have examined specimens from northeastern Lower 

 California, where they were taken at Angeles Bay and Las 

 Animas Bay. A young specimen from Smiths Island in the 

 Gulf of California possibly belongs here, although its dorsal 

 coloration is not typical, and I regard it as C. dickersonce.
