REPORT OF NATIONAL MUSEUM, 1898. 



We Lave here, tbeu, a tendency to tbe formation of a race, Avliicli is 

 not sufiticiently pronounced to liave produced a subspecies. 



The Crotaphytus uyislizenii belongs to tbe fauna of the Great Basin 

 division of tbe central region, ranging into tbe northern part of the 

 Souoran and into tbe southern part of the Pacific. 1 found it common 

 as far north as Pyramid Lake, in northwest Nevada, and Dr. Wortman 

 sent me specimens from the Bruneau River, in southwest Idaho. It 

 does not range nearly so far east as tbe C. collaris, not passing, so far 

 as known at present, tbe Pecos River of Texas. 



This is a very active species, and is more or less carnivorous in its 

 habits. I took from the stomach of one a fully grown Ufa stanshuriana. 



Crotaphytus unalizenii Baird and Girard.
