into a bush after a cicada, which it apparently failed to secure 

 Next it crawled slowly along, occasionally protruding its tongue. 

 When a fly buzzed about the bush and alighted on the ground 

 some two and a half feet away it raised its head and started a 

 little as if it recognized the sound. Then it crawled slowly up 

 toward the fly and as the insect left the ground the lizard jumped 

 four inches into the air after it. In executing this leap all four 

 feet necessarily left the ground. Once the lizard crouched down 

 on a gray sage-leaf background with which the color of its body 

 blended perfectly. 



Numbers of the females exhibited the red coloration charac- 

 teristic of some examples during the breeding season. The first 

 specimen showing this character was secured June 8, between 

 Quinn River Crossing and Big' Creek Ranch. 



Uta stansburiana Baird and Girard 

 Brown-shouldered Lizard 



Distribution. — Collected in greater numbers at Virgin Valley 

 than at any other locality visited. Specimens were secured as 

 follows: Virgin Valley (5000 feet), 12; Big Creek Ranch (4350 

 to 5000 feet), 10; Alder Creek Ranch (5000 feet), 2; Quinn 

 River Crossing (4100 feet), 1. Seen at Amos (4400 feet). 



The type locality of the brown-shouldered lizard is the 

 "Valley of the Great Salt Lake, Utah." It haS been recorded 

 from localities north and east of the Pine Forest Mountains, 

 but I can find no record of its occurrence in the Mount Shasta 

 and Warner Mountain regions of California, which lie to the 

 westward. No specimens of Uta were obtained by the Warner 

 Mountain Expedition of the Museum of Vertebrate Zoology in 

 1910. Possibly the species does not range far west of the Pine 

 Forest Mountains. 



As is the case with many of our reptiles, Uta stansburiana 

 was very much more common along the mountains than on the 

 open desert. 



Habits. — Uta stansburiana is characteristically a ground- 

 loving species, as noted by Van Denburgh (1897, p. 58), though 

 occasional individuals were noted either on boulders or in rocky
