Depth of body equal to the length of the head, three and two-thirds times in the 

 total length. Snout rounded, not projecting, three and one-third times in the length 

 of the head ; diameter of eye three and two-thirds times in the length of the head, 

 interorbital width three times ; mouth terminal, its width three and a half times in the 

 length of the head; lips feebly developed, not extending across the chin; barbels two 

 on each side, minute, the distance between them two-thirds the diameter of the eye. 

 Dorsal fin with III 8 rays, last simple ray not ossified, as long as the head ; the border 

 of the fin scarcely emarginate ; origin of the fin much nearer the end of the snout than 

 the root of the caudal fin. Anal fin with III 5 rays, longest two-thirds the length of 

 the head. Pectoral fin acutely pointed, three-fourths the length of the head, not quite 

 reaching the ventral ; latter below anterior rays of dorsal. Caudal fin deeply forked.

 line and ventral fin, 12 round caudal peduncle.

A single specimen from Lake Victoria, collected in 1903 by the late Mr. W. G. 

 Doggett, and presented to the British Museum by Col. Delme Radcliffe. 



The minute barbels distinguish this species from all its allies of the B.perlnce group. 



Examples of this species appear to have been first noticed by Hilgendorf (Sitzb. Ges. 

 naturf. Fr. Berlin, 1888, p. 78) as related to B. gobionoides, C. & V., and B. inermis, 

 Peters, and afterwards referred, with doubt, to B. pagenstecheri, Fischer, by Pfeffer 

 (Thierw. O.-Afr., Fische, p. C6).
