STERNOTHiERUS ODORATUS. 137 



seems rather to regard it as a variety of the Testudo Pennsylvanica, (Kinosternon 

 Pennsylvanicum,) than as a distinct species. 



Daudin next describes this animal, and from the same authority, but more 

 fully; he places it among those Testudines where the anterior section of the 

 sternum alone is movable. He says, however, that he "suspects" it is only a 

 simple variety; yet " he describes it as a distinct species, in deference to the 

 opinion of Bosc and Beauvais." 



Daudin again reproduces the same animal as the Testudo glutinata, which is 

 synonymous with the Testudo Pennsylvanica sterno immobile of Schoepff; but 

 still believing it to be a variety of the Testudo Pennsylvanica, (Kinosternon 

 Pennsylvanicum,) from which, however, the animal is not only specifically but 

 generically distinct. 



Say and many naturalists have referred this animal to the genus Cistuda of 

 Flemmg, with which its anatomical characters are at variance; and Dumeril and 

 Bibron have lately arranged it under that of Staurot}q)us of Wagler; but, I see no 

 good reason for removing it from that of Sternothserus of Bell.
