REPTILES AND AMPHIBIANS OF TEXAS 23 



53. Phrynosoma cornutum Harlan. Horned Toad. 



Texas Horned Lizard. 



Western, Central and Southern Texas. In the cre- 

 taceous region of the east-central portion of the 

 State, it is found as far north as Dallas. Absent 

 from most of the counties of the East Texas timber 

 belt and the north-central section. 



54. Phrynosoma modestum Girard. Little Horned Lizard. 



The trans-Pecos region and the plains from Clar- 

 endon south to the Rio Grande River. 



ANGUID>^ 



55. Ophisaurus ventralis Linn. Glass Snake. 



Eastern Texas from the northern boundary south 

 to the Rio Grande. Both eastern and western phases 

 occur together in the same localities in the coast 

 country. It is rare in the region about Waco, but 

 more common to the eastward, in the timber belt. 

 Kerrville is the most western record that I have been 

 able to find for this species. 



56. Gerrhonotus liocephalus infernalis Baird. 



Texas Gerrhonotus: Plated Lizard. 



This rare lizard has been recorded from only a 

 few scattered localities, mostly in the central -north- 

 ern, central and western sections of the State. It in- 

 habits rocky places and is our most pugnacious lizard. 

 The following are the published localities: Devil's 

 River, Helotes Creek and Wichita County (Cope), 

 Chisos Mountains, Brewster County, at 6,000 feet 

 (Bailey), Hays and Travis Counties and between 

 Lewisville and Roanoke, Denton County (Cragin). 

 My three specimens are each from a different local- 

 ity, i. e.. White Bluff, Burnet County, the hills west 

 of Austin, and the foothills of the Chisos Mountains.
