 to three times in the interorbital width ; width of the mouth two-fifths to one-half 

 the length of the head ; lips covered with granular papillae, the upper well developed, 

 bordered by large papillae forming a fringe ; lower lip forming a fold embracing 

 a mental disk, which is broader than long ; two small barbels on each side, not 

 measuring more than half the diameter of the eye. Dorsal with 10 rays, 7 of which 

 are branched, equally distant from the nostrils or the anterior border of the eye and from 

 the root of the caudal ; first branched ray longest, as long as or a little shorter than the 

 head ; border of the fin notched. Anal fin with II 5 rays, first branched ray longest, 

 two-thirds to three-fourths the length of the head. Pectoral as long as or a little 

 shorter than the head, widely separated from the ventral, which is situated below the 

 posterior half of the dorsal. Caudal fin deeply emarginate. Caudal peduncle once 

 and one-third to once and a half as long as deep. Scales 36-40 ~, 3 or 4 between 

 the lateral line and the root of the caudal, 16 or 18 round the caudal peduncle.

A coloured sketch made from a fresh specimen shows the fish to have been dark 

 olive-green above, greenish yellow beneath; a bright orange spot on the opercular 

 border, followed by a black spot on the shoulder ; dorsal, ventral, and anal fins 

 yellowish at the base, purplish grey in the distal half, with the tips of the anterior rays 

 orange ; a series of round black spots on the dorsal near its base ; pectoral fins dark 

 purple, yellow at the base ; some pink on the caudal ; iris bright orange.

This species was originally described by Eiippell under the name Chondrostoma 

 (lembeensis from a single specimen obtained by him at Goraza, Lake Tsana (also 

 known as Lake Dembea). Specimens were obtained from the same lake b\ Mr. E. De°en, 

 and the British Museum has also received the same fish from various localities in 

 Gallaland (Blue Nile and Omo systems) and from Mount Kilimanjaro.
