236 ctpeinid^:. 



between them a little greater than the diameter of the eye. Dorsal fin with IV 9 rays, 

 last simple ray very strong, bony, not serrated, feebly curved, about two-thirds the 

 length of the head ; free edge of the fin strongly emarginate ; its distance from the 

 occiput equals its distance from the root of the caudal fin. Anal fin with III 5 rays, 

 longest ray a little more than half the length of the head, not reaching the root of the 

 caudal fin. Pectoral fin about two-thirds the length of the head, nearly reaching the 

 ventral ; latter extending slightly in advance of the vertical of the origin of the dorsal. 

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

 Scales longitudinally striated, 31 gf, 2J between lateral line and ventral, 14 round 

 caudal peduncle. 



Dark olive above, silvery white beneath, the fins greyish. According to Mr. Zaphiro's 

 notes, the pectoral, ventral, and anal fins are tinged with pale red at the ends and the 

 iris is yellow.

A single specimen from the Didessa River (Blue Nile), altitude 1500 feet (6.5.05), 

 forms part of the fine collection of fishes made by Mr, P. C. Zaphiro and presented to 

 the British Museum by Mr. W. N. McMillan. 



JB. zaphiri is closely allied to B. gorguari, differing principally in the longer barbels.
