108 Species of Notth Atnerican Tortoises. 



with red, beneath with yellow. Feet palmate, five-toed ; 

 claws 5-4. 



Plates of the margin twenty-five ; of the sternum twelve. 



Length eight inches and a half, height three inches and three 

 quarters.

 which were carried by M. Bosc from this country to France, 

 and from which Daudin drew up his descriptions, and have 

 found them to agree, even in the most minute particulars, 

 with the two species which I have described under those 

 names.
