REPTILES AND AMPHIBIANS OF TEXAS 31 



stripes and spots, although the spots are usually in- 

 distinct, and is much the stouter animal of the two. 

 This is probably the same variety as the specimen 

 from Dallas referred to by Cope under the name of 

 E. sirtalis obscura (bulletin U. S. National Museum, 

 No. 17, 1880, page 23) . The other is more slender, the 

 red interspaces of the sides form bars as in parietalis 

 Say and I have usually referred it to that sub-species. 

 Since reading Dr. Ruthven's essay on the garter 

 snakes, however, I have modified my opinions and 

 now consider both to be merely forms of sirtalis. 



83. Thamnophis sirtalis parietalis Say. Red-barred 



Garter Snake. 



Recorded from El Paso by Cope and from Pecos 

 by Brown. Probably occurs throughout the district 

 south and west of the Pecos, but locality records are 

 lacking. The specimen from White Eagle Copper 

 Mine, referred to in my report on the reptiles of 

 Burnet County (Baylor University Bulletin, Vol. 12, 

 No. 1, page 8) , may have been one of the other forms 

 of the division of Thamno^phis containing eques, sir- 

 talis and pojietalis. 



It is quite likely, however, that parietalis does 

 range into the granite country as Uta ornata, Eume- 

 ces brevilineatus and other West Texas reptiles are 

 found there quite commonly. 



84. Tropidoclonium lineatum Hallowell. Lined Snake. 



Eastern Texas, west to Cooke, Dallas and Mc- 

 Lennan Counties, south to Walker, Harris and Lib- 

 erty Counties. Very abundant within the city limits 

 of Dallas, Houston and Waco in waste lands and un- 

 der storerooms and warehouses. 



85. Amphiardis inornatus Garman. Carman's Snake. 



The type specimens, two in number, were col- 

 lected at Dallas and are now in the Museum of Com- 

 parative Zoology at Cambridge. The species must 

 be very rare as no other examples have been collected 

 since it was described in 1883.
