GIANT SADDLE-BACKED TORTOISE. 22% 
From the few male specimens in museums this tortoise differs 
by the fore part of the shell being less strongly compressed and 
not reaching the same height, more as in 7. ephippium, by the 
“comparatively greater breadth of the hinder part of the carapace, 
by the broader bridge, and by the smaller size of the marginals 
bordering the bridge.
