TEXAN HERPETOLOGY 15 



was collected. 



Thamnophis marcianus Baird and Girard. Marcy's Garter Snake. 



Boquillas (Bailey) Paisano and Alpine. 



Thamnophis egues Reuss. 



Prade collected a fine adult specimen of this handsome, spotted garter snake 

 at a small tank near Alpine. 



Coluber emoryi Baird and Girard. Emory's Pilot Snake. 



I found a young example of this species under a fallen tree near Paisano 

 Pass. 



Crotalus atrox Baird and Girard. Texan Rattlesnake. 



Boquillas (Bailey) and Terlingua. 



Crotalus lepidus Kenn. Kennicott's Rattlesnake. 



Chisos Mountains and Paisano (Bailey). 



We did not see a single rattlesnake at Paisano during the ten days we were 

 camped there but this is easily accounted for by the earliness of the season. 

 This species is sometimes called the green rattlesnake, supposedly on account 

 of the color of the light bands, but Bailey describes his specimens as being dark 

 rusty brown with a pinkish tinge. A specimen in the Baylor Museum from 

 the San Bias Mountains, Chihuahua, when fresh, had the light bands salmon 

 colored. 



Chrysemys texana Baur. Texan Turtle. 



Chrysemys with yellow head markings were frequently observed in Calamity 

 Creek, and the larger tanks. A half-grown specimen from Calamity is a 

 fairly typical example of the species described by Baur, 



Kinosternon flavescens Agass. Yellow Mud Turtle, 



This mud turtle is abundant in tanks near Alpine. 



Terrapene ornata Agass. Painted Box Tortoise. 



Flats near Alpine. Du Bois Canyon.

Rana pipiens Kalm. Leopard Frog. 



Calamity Creek and tanks on Blackburn's Ranch. 



Acris gryllus crepitans Baird. Western Cricket Frog-. 



Same localities as Rana pipiens Kalm. 



Bufo lentiginosus woodhousii Baird and Girard. Western Toad.

My friend J. D. Mitchell, collected a number of juvenile examples of this 

 toad near Boquillas in the Big Bend of the Rio Grande.
