REPTILES AND AMPHIBIANS OP TEXAS 11 



9. Aromochelys carinatus. Gray. Keeled Mud Turtle. 

 I have collected this species in only one locality, 

 i. e., the San Jacinto River, Liberty County. It is 

 probably more or less common in many localities in 

 Eastern Texas, but very little work has been done 

 along herpetological lines east of the Brazos Valley 

 and the species may be much rarer than I at present 

 suspect. Yarrow, in his Check-list of North Ameri- 

 can Reptiles, records carinatus from the Medina 

 River, San Pedro and San Jacinto, all localities in 

 Southern Texas. Mr. Louis Garni sent me a young 

 example collected near Boerne, Kendall County.

10. Chrysemys troosti Holbrook. Troost's Terrapin. 



Mr. Carman records a specimen of this turtle from 

 Deming's Bridge, Matagorda County. 



11. Chrysemys elegans Wied. Cumberland Terrapin. 



This terrapin is distributed over the entire State. 

 It has been collected at Texarkana and at Browns- 

 ville. It is abundant in springs and streams in North- 

 western Texas and has been reported from as far 

 west as Pecos. 



12. Chrysemys mobilensis Holbrook. Mobile Terrapin. 



This larger representative of the southeastern 

 Chrysemys concinna Le Conte probably occurs in 

 Texas, although I have not been able to obtain a 

 specimen. The literature in regard to this species 

 and Chrysemys texana Baur is so hopelessly con- 

 fused that it is an impossibility to decide to which 

 one a reference really applies. If the Alabama speci- 

 mens that I have examined are really mobilensis, it 

 is a species very distinct from texana. Dr. Yarrow, 

 in his North American Check-list, records two speci- 

 mens of Chrysemys concinna from Brownsville. I 

 suspect that this reference applies to mobilensis. As 

 this turtle has so often been recorded from Texas, I
