of the length of the head ; the maxillary barbels extend to the 

 ventral or to the anal, those of the mandible to the base of the pec- 

 toral. Dorsal fin lower than the body ; its spine is slender, slightly 

 serrated behind, and two-thirds of the length of the head ; pectorals 

 as long as the head, with a spine which is longer than that of the

A very small adipose fin ; a short dorsal fin with a pungent spine ; 

 anal fin elongate, terminating at some distance from the caudal, which 

 is forked. Barbels eight : one to each maxillary, one between the 

 nostrils of each side, and four along the front margin of the lower 

 jaw ; the teeth on the palate form a more or less uninterrupted curved 

 band. Nostrils open, not prolonged into tubes, transverse-ovate; 

 the posterior nearer to each other than the anterior. Eye large, 

 situated behind, and partly even below the angle of the mouth. The 

 lower jaw is the shorter. Ventral with six rays.

The barbels are nearly equally long, extending to, or near to, the 

 extremity of the pectoral fin. The vomerine teeth form a very nar- 

 row band, which is angularly bent, and continuous with the palatine 

 teeth. The dorsal fin is scarcely lower than the body, and the length 

 of its spine is three-quarters or four-fifths of that of the head ; the 

 spine is serrated along its whole posterior side, and anteriorly at its 

 extremity. Pectoral fin nearly as long as the head ; its spine is ser- 

 rated posteriorly. Ventral fins half as long as the head. Silvery, 

 with three indistinct brownish longitudinal bands.

 This figure is slightly inaccurate in representing an anterior and posterior 

 pair of mandibulary barbels, whilst in reality the roots of the four barbels are 

 in a perfectly straight line.
