REPTILES AND AMPHIBIANS OF TEXAS 



and in a number of watercourses in Burnet and Mc- 

 Lennan counties. 

 Macrochelys lacertina Schiveigger. Alligator Snap- 

 ping Turtle. 

 This, the largest of all North American fresh-water 

 turtles, is by no means a common animal in the State 

 of Texas. Its occurrence here is first mentioned by 

 Baird in his list of the reptiles of the Mexican boun- 

 dary, but he does not cite any localities, merely add- 

 ing "Lowlands of Texas" under its name. Agassiz 

 states that it is found at Austin. The large specimen 

 exhibited by the National Museum at the Pan-Ameri- 

 can Exposition was from Southern Texas, but no 

 specific locality was given. 



Some years ago, in the San Pedro Springs zoo at 

 San Antonio, I saw a half-grown specimen which 

 was said to have been captured in the San Antonio 

 River. The Baylor Museum collection contains a 

 small example captured by Mr. J. D. Isaacks in the 

 San Jacinto River at Cleveland, Liberty County. 



CINOSTERNID.^ 



CiNOSTERNUM LOUisiANAE Baur. Louisiana Mud Turtle. 



Eastern Texas, west to the 98th Meridian; south 

 in the coast prairie country to Refugio. Probably a 

 variety of the eastern Cinostermim pennsylvanicum 

 Bosc, and Cope records specimens from Dallas under 

 that name. 



Mr. C. S. Brimley writes me that he has received 

 specimens of this mud turtle from Austin, Travis 

 County, and Colmesneil, Tyler County. Mr. Julius 

 Hurter of St. Louis, Missouri, collected a specimen 

 at Texarkana, Bowie County. I have collected speci- 

 mens in the following localities : Laguna Lake, Falls 

 County; San Jacinto River, Liberty County; Arroyo 

 Medio, Refugio County, and Dry Pond, Oak Lake, 

 Brazos and Bosque Rivers, McLennan County,
