Terrapene. 309 



Shell ovate, flattish, subcarinated ; spotted in a radiated manner. 



On examining some time since a shell of this species, the first 

 I had seen, which had lost the sternum, I was struck with the 

 appearance of the articular surface from which that part had been 

 removed, and immediately concluded that it miust belong to the 

 present group, having a moveable breast plate, notwithstanding 

 Merrem, to whom belongs the credit of having separated the 

 *' Box Tortoises" under his subgeneric division Terrapene^ retains 

 this species amongst his Emydes^ the character of which, in con- 

 tradistinction to Terrapene^ is, that the sternum is entire and 

 fixed. On consulting SchoepfF, I found that, with his usual accur 

 racy, that authour had mentioned the moveable structure of the 

 sternum, and subsequent observations have established my first 

 conjecture that it belongs to this genus.*

* " Sutura sterni transversalis media laxior est reliquis, et mobilitatem 

 aliquam concedit, ita ut uterque lobus, magis tamen anterior, ad superiorem 

 testam nonnihil propius admoveri possit." — Schoepff Hist. Test. p. 3, de Test.
