cesses, the presence of free bon^' tubercles on the sides of the body 

 and in the absence of a well-marked adhesive apparatus on the 

 chest. In most respects the genus is intermediate between Ere- 

 ihistes and Glyptothorax. 



I refer to this genus Pimelcdits asperiis, jMcClell.,' besides two 

 new species from the base of the Darjiling Himalayas described 

 below. McClelland's species was described from Chusan in China ; 

 it has been referred to the genus Hara, Blj'th, both by Giinther '■' 

 and Bleeker/ while Chaudhuri * has quite recently recorded it as 

 Erethistes asperus from Upper Burma (N. Frontier).

This species comprises small subcylindrical fish in which the 

 head is slightly depressed and the body arched both above and 

 below. The dorsal profile rises considerably from the tip of the 

 snout to the base of the dorsal, beyond which it slopes down to the 

 root of the caudal. The belly bulges somewhat downwards. The 

 head is long and broad ; its length is contained about y;^ times 

 in the length of the fish without the caudal fin. It is r2 times 

 as long as broad. The snout is broad and almost semicircular 

 in outline ; it is as long as the post-orbital part of the head. 

 The eyes are mirmte and are situated on the dorsal surface of 

 the head in the middle ; the}' are not visible from below. The 

 mouth is a wide transverse slit on the under surface of the head 

 a short distance behind the tip of the snout. The nostrils 

 are situated close together and are separated from each other 

 by a membranous flap bearing the nasal barbel ; they are situated 

 at an equal distance from the tip of the snout and the anterior 

 margin of the eye. There are eight barbels ; those of the maxil- 

 lary pair are broad at their bases and reach the bases of the pec- 

 toral fins. The outer mandibular barbels are longer than the 

 inner and are slightly shorter than the maxillary barbels. The 

 nasal barbels are as long as the distance between the nostrils and 

 the middle of the eye ; they are short and thin and are apt to be 

 overlooked. The dorsal fin commences greath' in advance of the 

 ventrals and its origin is much nearer to the tip of the snout than 

 to the base of the caudal fin ; its first divided ray is the longest 

 but is not so high as the depth of the body below it ; it contains 5 

 or 6 branched rays and two spines anteriorly. The dorsal spine is 

 strong and bony ; it is smooth anteriorly but somewhat roughened 

 posteriorly. The pectoral fin is almost as long as the head and is 

 provided with a strong spine which is serrated externally but inter- 

 nally it possesses about 7 hooked spines. The ventrals are not
