in the vicinity of Calcutta. This we doubt, as the species may be easily confounded with 

 young specimens of the Batagur and of the species allied to it. 



W. Elliott, Esq., has found this species on the banks of the Kistna and its tributaries, 

 where it is called by the natives Gunangi mek'ham. The beautiful drawings made from live 

 specimens which are in the possession of that gentleman represent the shell nearly uniform 

 brownish olive, and the sternal plates blackish with rosy margins ; neck and legs alternately 

 striped with greenish and blackish ; hinder part of the thighs with similar transverse bands. 

 A series of three or four red spots across the occiput. 



The figures C, C of Plate IV. represent the typical specimen, of half the natural size. 



Pangshura flaviventee. 



This species is easily distinguished from the two preceding by its bell-shaped first vertebral 

 plate and by its uniform yellowish sternum. It resembles much in form the P. tecta, but 

 is rather more elevated, having a large impression in the middle of the second and third 

 costal plates. 



Plates.- — Nuchal plate rather broader than long, broader behind than in front. The ver- 

 tebral plates are raised along their median line into a ridge, which terminates in a slight 



nodose prominence on the second of these plates, and in a strong one on tlie third. The 

 first vertebral shield is bell-shaped, longer than broad, and broadest behind ; it has six sides : 

 the anterior, in contact with the nuchal, is the shortest ; the next following pair, in contact 

 with the first marginal, are also short ; the lateral pair, in contact mth the costal, is S-shaped, 

 and rather long; finally, the hinder side is the longest, nearly straight, forming a broad 

 suture with the second vertebral plate ; the second and thii'd vertebi-als are rounded behind 

 and narrowed ; the fourth is much elongate, pear-shaped, tapering anteriorly ; the fifth is more 

 than twice as broad as the caudals. Caudals longer than broad, separated by a very small 

 notch. Hind margin of the upper shell not serrated. Sternum flat, slightly bent upwards 

 anteriorly, keeled on the sides, rather elongate, its width between the inguinal incisions 

 being one-half of its length. Gulars nearly as broad as long, the suture between them being 

 rather more than one-half of that of the postgulars The transverse sutures between post-
