General Hardwicke figures a spotted example of this species from 

 life, which is copied as T. punctata, junior, Gray, Illustr. Ind. Zool. 

 tab. His drawings also contain the figure of a much larger speci- 

 men from Futtehghur, which he says is " Bungoma," the country 

 name for the land Tortoise commonly called Terrapin. Back uni- 

 formly olive-green, upper part of head, neck, and limbs green, with 

 two pale orange spots on each side of the crown of the head. Lower 

 side with sternal callosities well developed. These figures are copied 

 in my Illustr. Ind. Zool. under the name of Trionyx granosus. 



It seems to be a very generally distributed animal in all parts of 

 India ; and the size of the tubercular plates on the sternum increases 

 and alters in shape with age ; and the Tortoise varies considerably in 

 colour, both from age and also, perhaps, from other causes. 



2. Emyda ceylonensis. 



Caudal callosities angular, parallel ; inner edge straight.

Hub. Ceylon. 



Dr. Peters, in the Monatsb. 1854, p. 216, describes an Emyda 

 vittata, and in 1868, p. 440, of the same work, describes an Emyda 

 scutata. I had thought that the former was the same as my 

 Emyda ceylonensis ; but in a letter which Dr. Peters wrote to me (on 

 the 26th February, 1871), he observes, " my Emyda vittata is quite 

 different from Emyda ceylonensis, having the abdominal plates much 

 smaller, and being in this respect more like Emyda punctata. My 

 E. scutata, on the contrary, more resembles E. ceylonensis." 



Dr. Kelaart describes the Ceylonese species as marked with 

 indistinct brown stripes on the back and head, characters which 

 Dr. Peters gave to E. vittata.
