Hub. Tidal streams, Calcutta. 



This species is very closely allied to U. granosa from which it is 

 separated by the small number of scales round the neck, by its two 

 postoculars and two pairs of large chin-shields and by differences in 

 the form of the shields of the head. 



Hydrophis Fayreriana n. sp. 



Head short and thick, snout broad, rounded ; body moderately long, 

 stout, of nearly equal breadth throughout and narrower on the 

 anterior fifth. Frontal shields large, tapering outwards, about 

 the same size as the nasals. One prseocular, small and pointing 

 forwards. One postocular. Seven upper labials, the 5 th the larg- 

 est, the 6th and 7th labials with a shield above them, suggesting 

 that they are only portions of a large 6th labial. Third and fourth 

 labials entering the orbit, oblong, higher than broad. The front 

 lower labials form a suture behind the mental and are succeeded 

 by a number of scale-like shields. Thirty-four rows of smooth 

 scales round the neck. Those on the ventral surface larger than. 

 those on the back and sides, and slightly imbricate, no enlarged 

 ventrals ; 193 scales from the chin to the vent. Five pairs of small 

 proeanal shields. 



Thirty-nine broad olive brown cross bands on the back, extending 



to the sides, but not on to the belly, rounded below, separated by 



narrow pale lines about half a scale's breadth. Tail olive brown 



above, black on its lower third. Length 30", 2'" ; tail 3", V" ; gape 



6.'" 



Rab. Bay of Bengal, Pooree Coast. 



This species appears to be closely allied to H. Hardwickii, from 



which it is distinguished by the absence of tubercles in the adults, 



the partial imbrication of the middle rows of scales on the belly, 



by their greater number &c. 



Hydrophis crassicollis, n. sp. 



Head hardly distinct from the neck. Neck and body of nearly 

 equal girth throughout. Round neck 2", 2'", round middle of body 

 2", 9'". Body elongated. Thirty-four series of scales round the 

 neck, 40 round the middle of the body. Scales almost smooth on
