Length of head 7| to 8, of caudal 8, height of body 7| to 8 in the total length. S«es— minute. 

 Bm-hels—sxK, the longest about 2/5 of the length of the head, l^ms— the dorsal arises in commencement of 

 the posterior thu-d of the distance between the eye and the base of the caudal fin, and midway above the 

 mterspace between the ventral and the anal. Caudal entire. ScaZes— distinct. CoZowr— light cinnamon. 



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

 an example from below Darjeeling, collected by Mr. MandeUi : 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, Blyth. 



Body elongated and compressed. A small, erectile, bifid, suborhital spine. Uight barbels, one rostral pair, 

 one maxillwry pai/r, and two mamdibular pairs. Dorsal fim, in the posterior third of the body, but cmt&rior 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.

 dorsal fin. Suborbital spine reaches to beneath the anterior third of the orbit. Scales — small, but distinct. 

 Colours — grayish, becoming dirty white along the abdomen. A dark lateral band extends from the eye to 

 the tail : along its first half are three black spots, whilst the whole extent of the back is irregularly lineated.
