Dr. C. H. Merriiim' gives the following iiccoimt of the habits of 

 CrotaphytUH collar is : 



The "ring-necked" lizard does not inhabit the Larrea belt of the Lower Sonoran 

 zone, but is sonimon in suitable places in the Upper Sonoran, whence it descends a 

 short distance into the Grayia belt. It lives among rocks, frequently in canyons, and 

 is commonest in the desert ranges. In the Panamint Mountains, California, it was 

 found in Surprise Canyon, in Emigrant Canyon, just above the Larrea (altitude, 1,400 

 meters, or 4, GOO feet). In the White Mountains it was secured in the canyon leading 

 from Deep Spring Valley up over the pass (altitude, 1,700 meters, or 5,600 feet), and 

 also high up on the west slope, always among rocks, and Mr. Nelson collected it in 

 the Argus Mountains and in Coso Valley. In Nevada it was rather common on the 

 west slope of the Charleston Mountains below Mountain Sj>ring, and was found also 

 in Oa.sia Valley, at Quartz Spring, at the west part of the Desert Mountains (altitude, 

 1,520 meters, or 5,000 feet) ; Utah (altitude, 1,830 to 2,040 meters, or 0,000 to 6,700 f«et), 

 and in the upper part of Pahranagat Valley. 



In Utah a very dark form was found in company with a black Ibrm of Sceloporus 

 iiseriuiiis on the black lava rock in Diamond Valley, between St. (Jeorge and the 

 Upper Santa Clara crossing.
