Habits. This animal, so far as I know, does not dilTer in its habits from the 

 Emydes in general. 



Geographical Distribution. Tennessee is the only state in which this 

 animal has been observed, though it doubtless inhabits many others of our 

 western country. 



General Remarks. It is again to Professor Troost that I must return my 

 thanks for having procured me a hving specimen of this beautiful Emys; which he 

 says is the most abundant of all in Cumberland river.
