652 Records of the Indian Museum. [Vol. XXII, 



the head and their superior margin is coterminous with the dorsal 

 profile ; the diameter is contained 5 times in the length of the 

 head. The interorbital space is somewhat concave and is 2'2 

 times as broad as the diameter of the eye. The snout is thrice 

 the diameter of the eye and bears a well-developed median pro- 

 boscis, which extends almost to the anterior end of the snout. 

 The dorsal profile of the proboscis is convex and the ventral 

 concave ; it is constricted in the middle and is tuberculated near 

 the anterior swollen end. The snout is marked by a deep trans- 

 verse cleft near its anterior end and bears two prominent tuber- 

 cular areas ; when seen from below the snout appears to be 

 trenchant and shows a well-defined almost semicircular lobe near 

 its tip. The nostrils are situated externally at the base of the 

 proboscis a short distance in front of the e^-e. The posterior 

 nostril of each side is completely covered by a rectangular lid. 

 The slit of the mouth is arched and the mental disc is well 

 developed. There are two pairs of barbels shorter than the dia- 

 meter of the ej-e. The gill-openings extend for a considerable 

 distance on the under surface and are separated from each other 

 by a distance slightl3' greater than the diameter of the eye ; the 

 opercular bones are not followed by a fleshy flap posteriorh'. The 

 lateral line is almost straight and is in the middle of the body ; 

 there are 32 scales along its length and 7 longitudinal rows between 

 the bases of the dorsal and the ventral fins. The dorsal fin is 

 situated nearer to the tip of the snout than to the base of the 

 caudal fin ; its base is equal to the length of the head in front of 

 the posterior margin of the orbit ; the first branched ray is the 

 longest and is much higher than the body ; the free margin of the 

 fin is concave. There are eight branched rays in the dorsal 

 besides three that are not branched. The ventrals are situated 

 below the middle of the dorsal and their origin is slightly nearer 

 the base of the caudal than the end of the snout ; they extend to 

 the anus and are somewhat shorter than tlie pectorals which are 

 considerably shorter than the length of the liead. The anal almost 

 extends to the base of the caudal fin. 



The air-bladder is small and the scales on the chest and on 

 the middle of abdomen are poorh* developed. 



The unique specimen of the species had been opened out 

 and the viscera removed, but still I have been able to find a few 

 minute eggs in the oviduct. It is a female 109 mm. in length 

 without the caudal fin. 



Type-specimen. — F 9953/1, Zoological Survey of India (Ind. 

 Mus.). 



Locality. — The specimen was purchased from Day and is the 

 original of the figure referred to above. It was collected for him 

 " by Dr. Waagen from the Nilwan ravine near the Shapur salt 

 ranges, " Punjab. 



Since the above description was written, I have found several 

 specimens of the species in the unnamed collection of the Indian 

 Museum from the Khewrah gorge (alt. 2000 ft.) in the Jhelum
