Cruz (the vicinity of Pete Mountain and in Agua Caliente, 

 Josephine and Gardner canyons in the Santa Rita Moun- 

 tains, Mo wry in the Patagonia Mountains, Calabasas, No- 

 gales), and Cochise (Fairbank, Fort Huachuca, Carr, 

 Miller, Montezuma, Brown, and Ramsey canyons in the 

 Huachuca mountains, Warren, Parmalee, Bisbee, and in 

 the Chiricahua Mountains at Rucker Canyon, Cave Creek 

 and Paradise), counties. 



It also occurs in Sonora (two miles south of Nogales, 

 Pinetos Camp 32 miles south of Nogales, Duros Millos) 



Habits. At Yuma this lizard is very abundant but is 

 rarely seen on the ground, preferring to climb over the 

 rough bark of the willows or to hide between the planks 

 of the railroad bridges. It feeds chiefly upon small insects. 

 At Tucson it frequents trees, fences, and piles of stones. 

 Dr. Coues states, that he satisfied himself that the same 

 individual assumed different colors. We know this to be 

 true of other Utas and many other Iguanidse, and it prob- 

 ably is true of most of the members of this family.
