Originally I regarded these specimens a? the young of G. 

 dorsalis, but on dissection I found the females full of eggs. Besides 

 the smaller size, the species is distinguished from G. dorsalis by 

 differences in the proportions of the body, the colouration and by 

 the number of denticulations on the pectoral spine. 



The largest specimen is 36 mm. in length. 



Unfortunately the specimens are lost ; but the figures clearly 

 show all the features.

This species is always confused by Manipuris with Macroiies 

 (Macronoides) affinis. 



All the specimens from Manipur are young ; they were only 

 found in the Imphal and the Amambi streams. 



The species is widely distributed in the waters of the C.anges 

 and the Irrawadi.

A few young specimens were collected in a small hill-stream 

 at Piphima, Naga Hills. 



Garra (Ham. Buch.). 



Three species of this genus were discovered in the Manipur 

 \' alley and the Naga Hills by the survey party and myself. Of 

 these two are represented by a large series in our collection while 

 the remaining one, which is new, is known from a single specimen. 

 In Mr. Pettigrew's collection there are three specimens of this 

 genus. They represent another undescribed form. 



The discussion on these species is given in another paper in 

 which I am publishing a revision of the genus Garra. The names 

 that I propose to give to the new species are included in the list 

 for the sake of completeness.

Only one specimen, 28'5 cm. in length, was obtained ; it was 

 captured in Khurda stream near its origin from the Loktak Lake. 



The fins are much elongated. The ventrals are longer than 

 the pectorals and reach beyond the base of the anal, which hi 

 turn extends beyond the base of the caudal fin. The dorsal fin 

 has a fairly long base.
