20 J. Anderson — Reptilian Accession to the Indian Museum. [No. 1, 



the neck and anterior third of the body ; two feeble keel-like tuber- 

 cles, one before the other, very obscure, but more strongly developed 

 on the two posterior thirds, ventrals twice the size of the adjoining 

 scales, quite smooth, broken up here and there on the posterior five 

 eighths of the body. Two pairs of anal shields, the central pair of 

 moderate size, elongate, the external pair very large. The vertical is 

 pointedly linquate. One prse- and two post-oculars. The 3rd, 4th 

 and 5th labials enter the orbit on one side, but only the 3rd and 4th 

 on the opposite side, the 5th being transversely divided into two 

 shields which do not reach quite as high as the orbital margin. 

 Two pairs of large chin shields, the anterior pair quadrangular, 

 and the posterior pair rather elongated. Olive yellow above, yel- 

 lowish on the sides and under surface, 62 broad black bands on 

 the back, contracting to a point on the sides, but prolonged very in- 

 distinctly on to the sides and central aspect, when they expand as a 

 large blackish spot. Near the tail the dorsal bands become con- 

 nected together, and their continuations on the central aspect follow 

 a similar arrangement. Six black rings on the tail, confluent be- 

 low ; the latter third entirely black. Length (total) 4 feet, 5", 6"' ; tail 

 4", 3'". Hughli, below Calcutta. The peculiarity of this species is 

 its elongated body, the uniform breadth which it preserves through- 

 out its length and its enlarged and smooth ventrals. 



Crotalid^;. 

 Hypnale afnnis, n. sp. 



Snout short, triangular, slightly concave above, canthus rostralis 

 prominent ; point of snout turned up, with the linquate shaped ros- 

 tral directed forwards and upwards, capped by 4 small and rather 

 nodular scales ; frontals broken up in a number of small scales, sym- 

 metrically arranged. Occipitals as large as supraciliaries, irregular- 

 ly shaped and tending to divide in the middle, irregularly trun- 

 cated behind, one in one direction and the other in another. Three 

 prseoculars forming the posterior boundary of the loreal pit. Two 

 postoculars, the lower one very large, forming the edge of the eye 

 and reaching to the lower pra3ocular. Two large temporals, widely 

 separated from the occipitals and diminishing in size from before 

 backwards. Eight upper labials, the second forms the lower mar-
