 Hills and the Manipur Valley.

The fishermen of Manipur do not make any distinction 

 between this fish and Gagata ccnia, both of which are called 

 nga-rang. The body is dotted with black spots which are aggre- 

 gated in certain regions to form 3 or 4 indistinct vertical bands. Both 

 the adipose and the spiny dorsal are edged with black. The 

 alimentary canal is simple and has only two coils in its entire 

 length. 



Reference may be made to the importance which has been 

 attached to the number of serrations on the pectoral spine. I 

 have, however, found on examining a large number of specimens 

 that the number of serrations is variable not only in different 

 individuals, hut even in the spines of the two sides of the same 

 specimen. 



There are four specimens from Amambi stream near Karam 

 lyakai, about 8 miles from Imphal on the Burma Road. 



M. affinis is known from Burma and the Manipur Valley. 



Glyptothorax dorsalis, Vinciguerra. 



iSSq. (il yptothorax dorsal is. Vinciijuerni, op. cit., p. 24(1, pi. vii, tiy. 4. 



There are ten specimens of this species five from the Imphal 

 stream and the rest from Amambi stream, some eight miles from 

 Imphal on the Burma road. 



The maxillary barbels reach the posterior margin of the base 

 of the pectoral fin ; the upper surface of the head and body is 

 tuberculated, the tubercles being arranged in longitudinal rows. 

 The dorsal spine is roughened externally and is smooth along its 

 inner border; that of the pectoral fin is flattened and has ir 

 denticulations internally. 



Most of the female specimens are full of eggs. 



The species is known from Burma and the Manipur Valley. 



Glyptothorax minutus, sp. nov. 



D. 1/6. A. 3/9. 



The length of the caudal fin is contained 5 — 5^ times, the 

 depth of the body 5J — 6 times and the length of the head 5^ — 5I 

 times in the total length including the caudal fin. The head is i^ 

 times as long as broad The eyes are minute, situated in 

 the beginning of the posterior half of the head, they are dorso- 

 lateral in position and are not seen from the ventral surface. 

 Barbels. — The maxillary pair reach the base of the pectoral, the 

 nasals reach the eye, the inner mandibular reach the anterior
