The Geographic Tortoise probably occurs in every part of the State, 
having been obtained at Toledo, Rockport, and Cincinnati. They are 
very bold, active, vigorous animals, approaching even the Chelydride 
in disposition, and their flesh is said to be very palatable. 
A specimen before me shows an abnormality, having an extra verte- 
bral and two extra costal plates, one on each side.
