Peak, however, they were too lively to be noosed. The ones observed 

 in the valley by Hidden Lake were surprisingly wild, even on a cold 

 gray morning darting immediately under the rocks. 



Sceloporus magister Hallowell 

 Rough-sealed Lizard 



Distribution: At Cabezon, 1700 feet, two adult males, nos. 180, 

 188, were taken; at Dos Palmos Spring, 3000 feet, one adult and one 

 juvenal, qos. 488, 490, were secured. One individual was seen at 

 Snow Creek-. 



In general coloration these forms are more grayish than material 

 from other localities. The juvenal color is of a light yellowish ante- 

 riorly and bluish posteriorly. 



This species is a typical desert form and is found under yucca 

 or cactus plants.

Sceloporus orcutti is found in Lower and Upper Sonoran and in 

 the Transition zones, but its center of population seems to be in 

 Upper Sonoran. It migrates into the upper edge of Lower Sonoran 

 and appears in Transition on the Fuller's Mill rid?e. It is associated 

 with the Sonoran chaparral characterized by sagebrush, manzanita, 

 and scrub-oak. 



In the scalation of Sceloporus orcutti one notices that the caudal 

 scales are strongly keeled, although Van Denburgh (1897, p. 87) calls 

 them nearly smooth. Strong keels were found in all the specimens of 

 S. orcutti in the Museum. The dorsal scales are described as varying 

 from no keels to very obtuse ones, with points scarcely protruding 

 beyond the scale. The <S'. orcutti of the San Jacinto region all show 

 obtuse keeling of the dorsals. In several the tendency to sharper 

 keeling and longer points is very noticeable.
