Louis, Stoddard, Pemiscot, and Pettis Counties. (Osage 

 Eiver, Agassiz). In Illinois, Monroe, St. Clair, and Madi- 

 son Counties. 



Habits. — The Troost's Turtle is common in the Missis- 

 sippi Eiver and in the adjoining lakes and sloughs left 

 by the receding water. They are mostly captured by 

 seining. With Pseudemys elegans a great many are sent 

 to the markets of eastern cities. On a visit to Baltimore 

 many years ago I found at a fish market a barrel full of 

 these two turtles, which the owner told me had come from 

 St. Louis.
