 broad, flattened, nor with sharp margins, its edge sometimes having a thin, 

 deciduous horny covering.* Barbels four. Pharyngeal teeth pointed, 

 hooked, 5, 3, 2/2, 3, 5. Dorsal fin rather short, with a strong, osseous, 

 serrated ray, and arising opposite the ventrals ; anal short. Scales 

 very small, the vent and base of the anal fin in a sheath, covered by en- 

 larged, tiled, scales. Lateral line passing to the centre of the base of 

 the caudal fin.

 it should be carefully investigated in fresh specimens.
