P. Cantorii, Gray. 



GUtra Indica, Gray. Gunther, I. K. form only the colours 



and marking form a life-drawing of Chitra, Sup., Cat. 



S. R., p. 91. 



Dissimilar as are the proportions of the skulls of this species 



and Chitra, they are extremely alike externally. It is a very 



much smaller animal however, but specimens are scarce in 



collections. 



Inhabits Arakan, Calcutta, Allahabad, "Malacca" (Cantor). 



Family TeiontcidjE. 

 Fresh water Chelonians with three claws on all feet and 

 powerful lower jaws. Carnivorous. Eggs, globular, calcareous.

callosities in adults five, the anterior lunate one, only being 



developed in aged individuals.* Young either 'oceUated' or

 This species is somewhat variable in its colour, and varies from 

 light to dark green or greenish olive of various shades. The 

 head is marked by radiating black lines, or by less regular 

 anastomosing lines (as in Buchanan Hamilton figure of ' Hurum') 

 and is handsomely ocellated when very young, though young 

 specimens are not so common as might be expected from the 

 numbers of adults brought for sale to the bazaars. The skull is 

 very stout and with a short facial profile. The palate broad and 

 sunken with parallel sides, and the mandible with a very feeble 

 median tubercular ridge on the inside, with two marked ridges 



* Homologous to tlie bo called ' sternal pair.' Sup., Cat. S. R., p. 96 of Lande- 

 mannia ; tlie granulations occasionally spreading from two lateral points.
