Mr. BELL on two new Genera of Land Tortoises. 397 
and short; the caudal scuta truncate, in contact with the 
upper shell, excepting a slight emargination for the passage 
of the tail; the spaces for the hinder legs very small and 
contracted. 
As I have only seen the shell of this species, I am unfortu- 
nately obliged to confine the description to that part. 
I have in my collection two specimens of this Tortoise, which 
differ considerably from each other both in colour and form. 
In one, the ground-colour of the upper shell is deep black, the 
radiations of a bright clear yellow, and the sternum of a light 
yellow: the arez of the dorsal scuta are quite flat, and the 
hinder part of the back somewhat depressed. In the other, the — 
ground-colour is of a deep blackish-brown, the radiations very 
obscure, and the sternum of a brownish-yellow colour, the ante- 
rior lobe being the darkest part: the dorsal scuta are elevated 
in the centre, and the back is everywhere evenly rounded, form- 
ing nearly a semicircular outline. "Notwithstanding these points 
of dissimilarity however, which give at first sight a strikingly 
different appearance to the two specimens, the essential charac- 
ters both of marking and of structure are sufficiently preserved 
to identify them as individuals of the same species.
