6. CiNOSTERNUM FLAVESCENS Agassiz. Yellow Mud Tur- 



tle. 



This species has a wide distribution, its range cov- 

 ering all but the extreme eastern section of the State. 

 It is the tank turtle of the Panhandle, the trans-Pecos 

 region and the southwestern counties. It is not un- 

 common as far east as Waco, but does not seem to 

 range much further than the Brazos river lowlands. 

 Hon. J. D. Mitchell has sent me specimens from Vic- 

 toria, but I have seen neither specimens nor records 

 from the eastern Rio Grande Valley, although it 

 probably ranges through the whole of Southern 

 Texas. 



7. CiNOSTERNUM HENRici Le Coute. Henry's Mud Turtle. 



Trans-Pecos Texas, ranging east of the Pecos 

 River, crossing the Edwards Plateau almost to San 

 Antonio. Cope records this species from Medina, 

 Medina County. Mr. Brimley has received specimens 

 from El Paso, and the Baylor Museum collection con- 

 tains one from the same locality. 



8. Aromochelys tristycha Agassiz. Southern Musk 



Turtle. 



This turtle is probably, as Mr. Brimley suggests, a 

 mere variety of Aromochelys odoratus Bosc, and 

 many specimens are hardly distinguishable from that 

 species. It is supposed to always differ from odoratus 

 by having the carapace more elongated, the central 

 shield of the plastron narrower, and a slightly differ- 

 ent coloration, especially about the head. My exper- 

 ence would indicate that musk turtles were not very 

 common animals in Texas, while on the other hand 

 the species of Cinosternum are wonderfully abun- 

 dant. The southern musk turtle is distributed over 

 Eastern Texas, ranging west to the granite country 

 in Llano and Burnet Counties and south into Bexar 

 and Medina counties. In some localities it is associ- 

 ated with Aromochelys carinatus Gray,
