The following are the colours in the living male specimen. 
Carapace. including the keels, uniformly black or almost dark 
bronze. Plastron dull yellow, with two spots on each bridge. 
Anterior portion of the head, including the upper and lower jaws, 
bright yellow with a red spot on the summit of the snout. Pos- 
terior portion of the head and also the neck brown. Iris red and 
a tinge of the same colour on the upper eyelid. Limbs and tail 
black.

level. 
The new species is most nearly related to G. tricarinata, Blyth, 
a terrestrial tortoise occurring in Bengal and Assam, with which it 
agrees in the imperfectly webbed digits and yellow plastron, but in 
the latter the carapace is much more convex, the three keels are 
yellow, the upper jaw is not hooked and there are other well-marked 
differences. G. tvijuga (Schweigger) the only other member of the 
genus hitherto met with in India, of which I obtained the striking 
variety described by Anderson as var. coronata (Anat. Zool. 
Researches, Yunnan, p. 729, 1878) at Chalakudi, is an aquatic 
species with many points of difference. In G. spenglerz (Gmelin) 
from Japan, China, Borneo and Sumatra, which agrees with the 
new species in its depressed carapace and hooked upper jaw, the 
digits are webbed and the margins of the carapace are strongly 
serrated.
