fins. Nostrils. — There is a pair of nostrils on each side and their 

 position is nearer to the eye than to the tip of the snout. Fins. — 

 The dorsal commences almost opposite the ventrals ; its origin is 

 equidistant from the anterior margin of the orbit and the base 

 of the caudal fin. It is almost as high as the depth of the body 

 below it. The pectorals are shorter than the head and are separ- 

 ated from the ventrals by their own length. The ventrals do not 

 reach the vent, which is situated on a raised papilla and is provided 

 with thick lips. The caudal fin is slightly emarginate and in 

 some examples the lower lobe is longer than the upper. The 

 bases of the ventrals are provided with fleshy pendants. 



There are seven to eleven broad black bands on the body 

 separated by an equal number of white ones which are only half 

 as broad. There is a black bar at the base of the caudal fin and 

 a black spot at the base of first three rays of the dorsal. In some 

 examples the bands in the anterior region get mixed up and the 

 surface becomes uniformly dusky. The under surface of the head 

 and body is white. Usually there are two black streaks radiating 

 from the eye to the snout. 



I have not been able to discover any outward signs of sexual 

 dimorphism in this species. Some specimens on dissection were 

 found to contain eggs. The eggs in this species are fairly big. 

 In a specimen 43 mm. long, the diameter of an egg is 18 mm. 



Nemachilus kangpipkhulensis is widply distributed in the hill- 

 streams of the Manipur Valley.

The length of the head is contained 5 — 5i times, of the caudal 

 fin 4I — 5 times and the depth of the body 5 — 7 times in the 

 total length including the caudal fin. In ripe females the greatest 

 depth of the body is contained 5 times in the total length. Fyes. — 

 The eyes are invisible from below and their diameter is contained 

 3I — 5 times in the length of the head. Barbels. — There are six 

 fairly long barbels, the inner rostrals extend to the nasal opening 

 and the outer reach the beginning of the second third of orbit. 

 The maxillary barbels are as long as the outer rostrals and are 

 twice as long as the diameter of the eye. Lateral line. — The lateral 

 line is well-marked anteriorly, gradually it fades away and ulti- 

 mately disappears behind the anal fin. Fins. — The dorsal fin is in 

 advance of the ventrals and its origin is nearer to the snout than 

 to the base of the caudal fin. The pectorals are longer than the 

 head and when adpressed almost reach the base of the ventrals 

 which are provided with a short fleshy pendant. The caudal fin is 

 deeply forked and in some female examples the upper lobe is slightly 

 the longer. The caudal peduncle is i\ times as long as high. In 

 mature females the pectorals do not reach the ventrals.
