REPTILES AND AMPHIBIANS OP TEXAS 29 



localities in which I have studied the habits of this 

 snake, I have always found it in lagoons and bayous 

 with heavily wooded banks, never in open lakes or 

 streams. This subspecies and transversus occur in 

 the same localities, but never, so far as my expe- 

 rience goes, in the same habitats. 



75. Tropidonotus sipedon transversus Hallowell. 



Hallowell's Water Snake. 

 This is the common water snake of Texas and 

 is found in suitable localities throughout the State. 

 Unlike fasciattis, this species is partial to open 

 streams. 



76. Regina clarkii Baird and Girard. Clark's Water 



Snake. 



Coast region from Louisiana to the mouth of the 

 Rio Grande river. Recorded from Dallas (Cope) and 

 Pecos (Brown) but the majority of the published 

 records are from the vicinity of salt water. 



77. Regina grahamii Baird and Girard. Graham's Water 



Snake. 



Eastern Texas, west to Waco and south to the 

 neighborhood of San Antonio. Its distribution is 

 very local. At Waco up to and including the year 

 1912, 1 had collected only one specimen. In the spring 

 of 1913, I found it rather common at Cottonwood 

 creek, only about three miles south of the city. Here 

 I captured several and observed at least half a dozen 

 more in the course of one morning. 



78. Thamnophis proxima Say. Long's Garter Snake. 



This garter snake is abundant in all Texas east 

 of the plains and the Pecos river. Brown's Pecos 

 record indicates that it enters the trans-Pecos region 

 and Ruthven lists a specimen from Tule canyon. 

 Swisher County, west of the foot of the plains, but 

 it must be exceedingly rare in the extreme western 

 part of the State.
