 Barbels— six, the longest about 2/5 of the length of the head. Fi7is—the dorsal arises in commencement ot 

 the posterior third of the distance between the eye and the base of the caudal fin, and midway above the 

 interspace between the ventral and the anal. Caudal entire. .Series— distinct. Colour— Wght cinnamon. 



Hahitat. — North-east Bengal, the northern portions of the British and Upper Burma. I have received 

 an example from below Darjeeling, collected by Mr. Mandelli : it agrees with the others, except in having no 

 scales, but as it is not in a good state, 1 conclude they may have been rubbed off. 



Genus, 6 — Apua, Blyfh. 



Body elongated and compressed. A small, erectile, bifid, suborbital spine. Eight barbels, one rostral pair, 

 one maxillary pair, and two mandibular pairs. Dorsal fin in the posterior third of the body, but anterior to the anal 

 Ventral fins absent. 



Geographical distribution.— The single species of this genus, which has yet been discovered, was obtained 

 near Pegu in British Burma.
