between Renging and Rotung, measuring 36 mm., collected on the 

 9th January, 1912. 



The latter record affords some clue to the breeding season of 

 this mountain barbel, for the young specimen was probably in its 

 first year. It is interesting to note in this connection Captain 

 F. H. Stewart's remarks on the breeding habits of Schizopygopsis 

 stoliczkae (Rec. Ind. Mus., vol. vi, p. 84). 



Labco angra (H. B,). 



Yembung, iioo ft. Two specimens, both in a damaged condi- 

 tion. 



Both examples agree with Burmese specimens in lacking the 

 black lateral band, but differ from them in being without the black 

 blotches on the side of the tail. Barbels also are wanting, as in 

 Burmese examples, in one specimen (P. '-^)\ in the other, barbels 

 are present as usual. 



Yembung. 

 Dibrugarh. 



Labco dyochilus (McClell.). 

 Cirrhina reba (H B.). 

 Barbus chola (H. B.). 



Dibrugarh ; four specimens. 



The customary dark blotch on the sides is entirely absent. In 

 some a black spot and in others a black band is present on the 

 dorsal fin. The caudal fin is tinged with blue in the middle. 



Barbus hexagonolepis, McClell. 



Yembung, iioo ft. One 3^oung specimen 60 mm. (without 

 caudal) and another very 5^oung scarcely longer than 15 mm., 

 probably only a month old. 



These specimens were collected between the 13th and the 17th 

 January, 1912. The record gives an approximate idea of the 

 breeding season and the rate of growth; the young specimen, 

 60 mm. in length, is likely to be a fingerling of a year's growth. 

 On the 17th January, Major Wilson caught an unripe female of a 

 total length of 664 mm. (without caudal) weighing 15 ft. 



Barbus hexastichus, McClell. 



Yembung, iioo ft. Three adult specimens much damaged and 

 three young specimens in good condition 



In the adult specimens the eyes appear to be larger, and the 

 dorsal fin longer than usual. In the young specimens the dark 

 band along the lateral line ends in a black blotch in front on the 

 root of the caudal fin.
