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

 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 5 rays, the longest one-half to tliree- 

 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

 Scales with fan-shaped striation, 29-31 gf, 3 between lateral line and ventral, 12 round

Described from five specimens obtained near Fort Portal, 12 miles east of Ruwenzori, 

 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 

 Euwenzori, which it probably ascends from Lake George. It was not met with 

 above 5500 feet.
