Differs from the preceding in the more depressed shell, the depth 
of which is not more than half the length, the smoothness in the

This form presents all the characters of 7’. gigantea, except that 
the supracaudal shield is undivided. Possibly both this and the 
preceding species are based upon individual variations of 7’. elephan-
