Body subcylindrical; snout pointed. Barbels very short, the maxillary pair the longest. Mouth small. Lips thick, the upper one fimbriated. Nostrils nearer to the eyes than to the snout. Scales conspicuous, with a raised keel along their centre. Their form, posteriorly, angular. Lateral line distinct. Fins. Dorsal arises slightly in advance of the ventral, and midway between the snout and the base of the caudal fin; its upper margin is straight. Pectoral reaches two-thirds of the distance to the ventral, and the latter more than halfway to the anal. Caudal deeply emarginate; lobes pointed. Colours. Brownish, with a wide serpentine band of a dark chestnut- colour running from the snout, through the orbit, to the base of the dorsal fin, which last has a black centre. Caudal deep brown, with white margins. A black bar across the base of the ventral. Three specimens, 2\ inches long, are in the museum. NEMACHEILUS BLYTHII, sp. n. B.iii. D. 2/7. V. 9. A. 2/5. C.19.

Diameter |- of length of head, 1| diameter apart, 1 diameter from end of snout. Body subcylindrical. The three pairs of barbels all longer than the diameter of the orbit. Fins. Dorsal arises midway between the snout and the base of the caudal fin, and opposite to the ventral. Caudal deeply forked, its lobes sharp. Scales minute. Colours. Rather bleached; brownish, darkest above, with a dark band at the base of the caudal fin. Two specimens, 3 inches long, exist in the collection. NEMACHEILUS CINCTICAUDA.

Height of head \, of body \ of the total length. Eyes. Small, situated in the middle of the length of the head, nearly 3 diameters from the end of the snout, 1| diameter apart. Rostral and maxillary barbels well developed, being nearly as long as the orbit. Free portion of tail longer than high. No projection on the praeorbital. Fins.
