 Gopherus agassizii (Cooper). 



The characters pointed out for this species by Mr. F. W. True (Proc. 

 U. S. Nat. Mus. iv, p. 440) I have found to hold in the additional speci- 

 mens before me, and there is no difficulty in distinguishing it from 

 Gopherus polyphemus, much less from G. berlandieri. The fact that a 

 specimen named Xerobates berlandieri (No. 10412) is recorded in Yar- 

 rows Catalogue of Beptiles and Batrachians in the U. S. National 

 Museum (Bull. U. S. Nat. Mus., No. 24, p. 38), as from Fort Yuma, Cal., 

 need not disturb anybody, as it is in reality a G. agassizii, and is re- 

 corded as such by True (torn, cit., p. 447). 



This species was originally described "from the mountains of Cali- 

 fornia, near Fort Mohave'/ (Cooper, Proc. Calif. Ac. Nat. Sc, n, p. 121), 

 and the National Museum has since received specimens from Fort 

 Yuma (exact locality ?). Dr. Cooper {I. c.) adds that " broken shells are 

 frequent on the higher parts of the mountains west of the Colorado, 

 where the Pah-Utes eat them."
