parently does not enter the northern section of the 

 timber belt, but has been recorded from almost every 

 other section. Specimens from the Central Texas 

 counties are rather dark in coloration, while those 

 from the dry regions of the west and southwest are 

 very pale. Several from El Paso County combine the 

 characters of the two western subspecies, frenatum 

 and piceus, having narrow crossbands in front and

103. Zamenis taeniatus taeniatus Hallowell. Western 



Coachwhip Snake. 



Cope records this beautiful snake from two local- 

 ities in the Rio Grande valley — Laredo and Eagle 

 Pass. The Eagle Pass specimen is the type of Masti-

104. Zamenis taeniatus ornatus Baird and Girard. Texas 



Coachwhip Snake. 



Known only from a few localities in Western 

 Texas. Bailey records specimens from near Corn- 

 stock and the head of Devil's river, and Brown lists 

 it from Pecos. The National Museum contains the 

 types from "between Indianola and El Paso," receiv-

 Springs," collected by Major Emory.

Southern and Western Texas. Not uncommon as

 south-central section in Kerr, Kendall, Comal and 

 Bexar Counties. Extends locally as far north as 

 McLennan County. 



106. Cyclophis aestivus Linn. Southern Green Snake. 



A rather common species as far west as the foot 

 of the plains and south to the Mexican boundary. In
