(1907). 
Depth of body equal to the length of the head, three and two-thirds to four times 
in the total length. Snout rounded, longer than the eye, which is four to four and a 
half times in the length of the head and about once and a half in the interorbital 
width ; latter three times in the length of the head; lips moderately developed, 
interrupted on the chin; barbels two on each side, the anterior once and a half to once 
_and three-fourths, the posterior twice to twice and a half the diameter of the eye, the 
distance between them about two-thirds the diameter of the eye. Dorsal fin with 
III 7 rays, last simple ray strong, bony, coarsely serrated behind, much shorter than 
the head ; free edge of the fin not emarginate ; its distance from the occiput less than 
its distance from the caudal fin. Anal fin with III 4 rays, the longest one-half to three- 
fifths the length of the head. Pectoral fin two-thirds to three-fourths the length of the 
head, not reaching the ventral ; latter below anterior rays of dorsal. Caudal fin deeply 
forked. Caudal peduncle once and a half to once and two-thirds as long as deep. 
Scales with fan-shaped striation, 29-31 = 3 between lateral line and ventral, 12 round 
caudal peduncle. Yellowish, back olive-brown ; a dark greyish lateral stripe with or

Described from five specimens obtained near Fort Portal, 12 miles east of Ruwenzon, 
at an altitude of 4500 feet, in a small stream, a tributary of the Mpanga, flowing into 
Lake George. 
Mr. Woosnam observes that this was a common fish in the eastern streams of 
Ruwenzori, which it probably ascends from Lake George. It was not met with 
above 5000 feet.
