HERPETOLOGY OF LOWER CALIFORNIA. II9 



This species has been found as far south as San Tomas, 

 in the northern part of the peninsula. 



A key to the North American species of the Ph. coro- 

 natum group * is given. 



I. — A long spine just behind the broad subrictal. Head plates of adults 

 yellow, sparsely dotted with brown. 



A. — Head plates convex and almost smooth. Ph. blainvilUi Gray. 

 B. — Head plates flat and rugose. Ph. frontale Van D. 



II. — No spine, or a very small one, behind the broad subrictal. Head 

 plates, of adiTlts, chiefly black or dark brown. 



Ph. coronattim Blainv. 



The present collection contains a single specimen of 

 this species. It (No. 579) was secured by Mr. A. W. 

 Anthony, at Valladares, L. C. 



Phrynosoma cerroense Stejn. 



Phrynosoma cerroense.

This species, from Cerros Island, is characterized by 

 having the lower row of peripheral spines " only indicated 

 by a few scattered small spines."

Without larger series of the other species than are at hand , 



the status of the Gerrhonoti from the "Cape Region" 



of Lower California cannot be satisfactorily determined. 



* Not including the insular Ph. cerroense.
