The following are the measurements of tht 

 men : — 



Total length including caudal 

 Depth of body 

 Length of head ... 



Diameter of ej-e 

 Length of snout 

 Interorbital width 

 Length of rostral barbels 

 Length of maxillary barbels 



The species is widely distributed in the streams of the 

 valley. A few specimens were taken in the Senapati stream near 

 Kairong in the Naga Hills.

The length of the head is contained 5 — 55 times, the depth 

 of the body 4 — jf\ times, the length of the caudal 5 times in the 

 total length including the caudal fin. The eyes are situated some- 

 what in the anterior half of the head, their diameter being con- 

 tained 4 times in the length of the head, i\ — i-^- times in the 

 length of the snout and i\ times in the interorbital width. Bar- 

 bels. — There are two pairs of short barbels. Scales. — There are 

 38 — 39 scales along the lateral line, 7 — 8 rows above it to the base 

 of the dorsal fin and 3 below it to the base of the ventrals. 

 There are 20 rows of scales in front of the dorsal fin. Fins. — 

 The origin of the dorsal is equidistant from the end of the upper 

 lobe of caudal and the anterior margin of nares. It is situated 

 far back and extends to about the middle of the anal fin. The 

 paired fins are well developed and possess a number of stiff rays. 

 The pectorals do not reach the ventrals, which in some examples 

 extend to the base of the anal fin. The auxiliary processes do not 

 go beyond the bases of the pectorals. The free margins of both the 

 dorsal and the pectoral fins are rounded. The lower lobe of the 

 caudal fin is slightly longer than the upper. 



The mandibular knob so characteristic of the genus is absent 

 in this species. 



The dorsal profile in front of the dorsal fin is almost straight, 

 but posteriorl3' it curves to the base of the caudal fin. The ventral 

 profile is deeply arched and is convex throughout. The skin on 

 the sides of the head is prominently tuberculate. 



Colour. — The dorsal surface of the head and body is black 

 with about g blue lateral bands. The band at the base of the 

 caudal fin is deeper in colour than the rest. The belly and the 

 under surface of the head, and the pectoral, the anal and the ven- 

 tral fins white. The caudal is dusky in its posterior half, and the 

 dorsal has a characteristic deep black band across its middle.
