The skull figured as Kachuga peguensis (fig. 20) was pur- 

 chased of a dealer to whom Mr. Theobald had sold it among 

 some reptiles said to nave oome from Pega, without any 

 special liabitat. and without indication of the specimen to 

 whiohit belonged. Mr. Theobald thinks that it is probably 

 an aberrant form of Tetraonyx Lessoniox Batagur trwittata 

 (P. '/.. S. 1870, p, 676); but the figures, I think, show 

 distinctly that this is a mistake.

The shell of this Tortoise, which has usually been classed 

 with Emys, has a contracted front and hind margin of the 

 . ivity of the shell, as well as the masticating surface of the 

 typical Batagws. 



Mr. Theobald observes that -'this species is very common 

 ;it Calcutta, though adults arc not very easily obtained." 

 It appears to be more allied to Batagur than to Emys, yet 

 he did not discover that the skull that I had figured as Ka- 

 1 1 Oldhami was the skull of this species, and considers 

 this species as very doubtful, as it is based on a skull only, 

 in the distinctness of which Mr. Theobald had no confidence 

 whatever (P. Z. S. 1870, p. 076). 



The palatine bones are very small and triangular, about 

 half the size of the basisphenoid, which is large and tri- 

 angular, broader and much longer than the basioccipital. 



Pangshura tecta (p. 60), add: — 

 Clemmys tecta, Strauch, CJielon. Stud. p. 3:5. 



Pangshura ventricosa (p. 60), add : — 

 Pangshura ventricosa, Gray, P. Z. S. 1870, p. 710, fig. 2. 



Shell dark brown, oblong, and ventricose above, reddish 

 yellow, varied with black beneath; the hinder margin entire. 

 Vertebral plates bluntly keeled in front ; the first pentan- 

 gular, twice as long as broad, narrow in front, and gradu- 

 ally narrower and truncated behind ; the second elongate, 

 suddenly narrowed and produced behind and rounded at 



the end; the third smaller than the second, pentangular, 

 notched in front, narrow, acute, with a sharp prominent 

 keel behind : the fourth, oblong, twice as long asbroad, six- 

 sided, suddenly contracted and produced in front. 



//k/'. Assam. 



This species is most like Pangshura tecta ; but the shell 

 is much more ventricoso, and the first vertebral plate is 

 much narrower and longer compared with its width, and 

 the second vertebral plato is very differently shaped, as is 

 also the fourth ; but this may be an unusual variation. 

 But the lightness, thinness, and ventricose character of the 

 shell marks it as a peculiar species. The fourth, sixth, 

 eighth, and especially the tenth marginal shields have the 

 upper edge produced and more or less extended up between 

 the sutures of the costal shields.

 Pangshura flaviventris, Gray, P. Z. S. 1870, p. 709. 



A series of shells of this species in the British Museum 

 from Delhi, where it is common ; but all the specimens, 

 like the one we recently received from Cuttack from Mr. 

 Day, have the sternum spotted, varied with black like the 

 other species of the genus ; the specimens only vary in 

 some having the first vertebral more or less distinctly urn- 

 shaped and contracted on the sides than the others. 



Jerdonella sylhetensis (p. 61), add: — B.M. 



Pangshura sylhetensis, Gray, P.Z.S. 1870, p. 709, fig. 1 

 (thorax only). 



Shell olive-brown, strongly and sharply dentated behind. 

 The sides of the back shelving, but ventricose and with a 

 central dorsal prominence. First vertebral plate five-sided, 

 truncated behind, rather produced in front, with a blunt 

 keel ending in a tubercle behind ; the second broadly hex- 

 angular ; the third elongate, narrowed and produced behind, 

 with a very prominent keel ending in an acute point behind ; 

 the fourth much elongated, narrow and produced in front, 

 with a narrow, sharp keel more prominent behind : the 

 fifth pentangular, longer than broad, the hinder sides being 

 as wide as three of the marginal plates. Underside pale, 

 black-varied.
