A young specimen of this species, measuring eleven and one half inches in 
direct length, Plate 10, does not differ greatly in its shapes from the smaller 
of the types originally described, which measured twenty-two inches, and of 
which the outlines are sketched on Plate 9 from the plate by Giinther, Trans. 
Zool. Soc. London, 1875, 170, pl. 35, fig. C. The carapace is a short broad 
oval, rounded in front and over the femora, and subtruncate across the caudal 
section. Its height is about half of the length; the back is broadly arched. 
At the nuchal notch the height is about half of that in the middle of the body. 
The strongest vertebral declivities occur from the areolar space of the first 
vertebral scale forward and from that of the fourth vertebral backward. The 
flanks are nearly straight and bear a low keel below the areolar spaces of the
