Depth of body three and one-fifth to three and three-fourths times in the total 

 length, length of head four and one-third to five times. Head small ; snout rounded, 

 not prominent, shorter than the eye, the diameter of which is twice and two-thirds to 

 three times in the length of the head ; interorbital width twice and a half in the length 

 of the head ; mouth narrow, with very thin lips ; no barbels. Dorsal fin with HI 8 

 rays, last simple ray not ossified and as long as the head; the border of the fin slightly 

 notched ; origin of the fin midway between the end of the snout and the root of the 

 caudal fin or a little nearer the former. Anal fin with III 5 rays, longest two-thirds 

 the length of the head, widely separated from the root of the caudal. Pectoral fin 

 acutely pointed, three-fourths the length of the head, not reaching the ventral ; latter

This species, dedicated to Mrs. Minchin, differs from the following species without 

 barbels in the greater number of scales in the lateral line and in the longer caudal 

 peduncle. It is described from twelve specimens obtained by Mr. Degen at Bunjako, 

 Lake Victoria, in November 1905.
