There has been some confusion between Barbus chagunio 

 (Ham. Buch.). B. spilopholus, McClell. and B. clavatus-, McClell. 

 .\t first McClelland ' considered B. chagunio to be "a variety of 

 the spotted barbel, B. spilophohis," but later in describing B. 

 clavatn% he remarked that "the collection now before us, affords, 

 however, a ver}' distinct species, which I believe to be the Cyprinus 

 chagunio, Buch." Giinther regarded .McClelland's two species as 

 distinct, but placed Cyprinus chagunio with a query under the 

 synonymy of B. clavatus. Day recognised B. chagunio as a 

 distinct species and regarded B spilopholus as its variety ; he 

 moreover considered B. clavatus as a distinct species. Chaudhuri * 

 recognised B. spilopholus as a valid species, but had no material 

 to decide about B. clavatus as it was then onlv known from McClel- 

 land's description which is unfortunately imperfect and meagre 

 and some casual remarks in it are misleading ; his figure of the 

 species is also poor. 



I take this opportunity to supply a short description and a 

 figure of the species from a few well-preserved examples collected 

 in Senapati stream near Kairong, Naga Hills, Assain.

 The length of the caudal fin equals the depth of the body 

 which is contained 4 — 4-|- times in the total length. The head 

 is short and conical, its length being contained 5— 5i times in 

 the total length ; it is comparatively longer in young specimens 

 than in the adult. The snout is shorter than the diameter of 

 the eye, which is contained about 3 times in the length of the 

 head. The caudal peduncle is ij — 2 times as long as broad. 

 Fins.^The origin of the dorsal is almost in the middle of the 

 distance between the end of the snout and the base of the caudal 

 fin, in some individuals it is nearer to the former. Its last spine 

 IS denticulated posteriorly and is almost as high as the depth of 

 the body below it. The free margin of the fin is deeply concave. 

 The caudal fin is very long and deeply forked, its rays are very 

 brittle. Scales. — There are 40—42 scales along the lateral line, 

 7 — 8 rows of scales above it and 33— 4^ below it to the base of 

 the ventral fin. In an oblique line there are in all ii rows be- 

 tween the bases of the dorsal and the ventral fins. There are 14
