Boulenger, Ann. & Mag. N. H. (7) x. 1902, p. 431. 



Depth of body three and a half to three and three-fourths times in the total length, 

 length of head three and one-third to three and a half times. Snout rounded, three times 

 in the length of the head ; diameter of eye four (young) to six and one-third times in the 

 length of the head, interorbital width three and one-fourth to three and three-fourths 

 times ; mouth inferior, its width four and a half times in the length of the head ; lips 

 much developed, the lower forming a short rounded lobe in the middle ; barbels two 

 on each side, the anterior two-thirds to three-fourths the diameter of the eye, the 

 posterior as long as the eye and as long as or a little longer than its distance from 

 the anterior. Dorsal fin with IV 9 rays, last simple ray very strong, bony, not 

 serrated, straight or very slightly curved, two-fifths to three-fourths the length of the 

 head ; free edge of the fin emarginate ; its distance from the occiput equal to or a 

 little less than its distance from the caudal fin. Anal fin with III 5 rays, longest ray 

 three-fifths the length of the head. Pectoral fin about two-thirds the length of the 

 head, not reaching the ventral ; latter below or slightly posterior to the origin of the 

 dorsal. Caudal fin deeply forked. Caudal peduncle once and two- thirds as long as 

 deep. Scales longitudinally striated, 31-33 ^J , 2^ or 3 between lateral line and ventral, 

 12 round caudal peduncle. 



According to Mr. Degen's notes, the fish when fresh is bluish olive above, yellowish 

 beneath ; fins dark slate-colour ; iris deep yellow. 



Total length 350 millimetres. 



This species inhabits Lake Tsana. Four specimens were obtained by Mr. Degen, 

 the largest at Zegi, May 31, 1902, the three others at Bahardar, June 4, 1902. 



B. brevibarbis differs from B. affinis and B. nedgia in the shorter anterior barbels.
