The colour is black all over except the under surface of the

The specimens of L. pangusia from Mani]3ur have a black 

 blotch at the base of the caudal fin and are apt to be confused 

 with those of L. angra. They can be distinguished from the latter 

 species by the possession of definite barbels instead of the maxil- 

 lary flaps inside the grooves, one on either side of the mouth, and 

 in having a triangular black spot just above the fifth scale of the 

 lateral line. The structure of the mouth and lips of the two spe- 

 cies is also different. 



Labeo pangusia is common in the streams of the vaHey and 

 three specimens were collected from the Loktak L,ake. The lake 

 specimens are darker in colour. 



Labeo angra (Ham. Buch ).

The Specimens of this species agree with Burmese examples 

 in our collection. They possess a fleshy flap inside the groove 

 instead of the maxillary barbels on each side of the mouth. There 

 is a deep black blotch at the sides of the tail. In certain young 

 individuals there is also an indication of a second blotch above the 

 middle of the pectoral fin. 



The specimens in the collection were found in the muddy 

 streams of the Manipur Valley. 



Crossochilus latia (Ham. Buch.).

This fish is found in abundance in the muddy streams of the 

 valley, and does not exceed 7 inches in length. 



The young specimens are slender in form and look somewhat 

 different from the adults. ^Manipuris call the young nga-rohi and 

 the adults nga-rohi-mapi, " the mother of nga-rohi." 



This is one of the commonest s]Decies found in the streams of 

 the ^lanipur \^alley.

The species is fairly common in the Imphal River and its 

 tributaries and is also found in the Loktak Lake. The lake speci- 

 mens are, however, darker in colour.
