centre of which is situated opposite the angle. Superior maxillary 
barbel reaches as far as the end of the pectoral fin; that on the lower 
jaw is short, and only equals one-third of the length of the head. 
Teeth sharp, carded, and recurved, in six or eight rows; in both 
intermaxillaries and lower jaw, and in two oblique spots on the vomer, 
separated by an interspace. 
Fins. Dorsal weak, expanded in the centre, arising opposite the 
commencement of the ventral; pectoral reaching to just beyond the 
origin of the anal, its spine serrated on its inferior aspect. Anal di- 
vided from the caudal by a notch, and covered for about two-thirds 
of its distance from the abdomen by a fleshy sort of sheath. Caudal 
lobed ; the superior lobe the longest. 
Lateral line straight from the upper margin of operculum to centre 
of caudal. . 
Colours. Greenish along the back; white along the sides, abdo- 
men, and chest, with a purplish tinge. The whole of the body mi- 
nutely studded with fine black points: a large, round, darkish finger- 
mark on the shoulder, opposite the centre of the operculum. 
Inhabits the same localities as the W. attu, and equally good for 
eating and salting. Said never to exceed 2 feet in length.

By no means rare in the rivers of Malabar. In two specimens the 
adipose fin was absent, perhaps lost by some accident ; probably from 
some such deformed specimen Dr. Jerdon described the Schilbe 
sykesit.
