260 CYPBINIDiE. 



little shorter than the head; the border of the fin feebly notched; origin of the 

 fin midway between the end of the snout and the root of the caudal. Anal fin with 

 III 5 rays, its longest ray about half the length of the head, not reaching the caudal. 

 Pectoral tin acutely pointed, shorter than the head, reaching, or nearly reaching, the 

 ventral; latter originating below the first ray of the dorsal. Caudal fin deeply forked. 

 Caudal peduncle once and one-third to once and a half as long as deep. Scales smooth, 

 19-21 gi, 1J between lateral line series, which is formed of very deep scales, and 

 ventral fin, 9 round caudal peduncle. Lateral line reduced to 3 or 4 tubules on the 

 anterior scales. 



A coloured sketch made by Mr. Loat at Lake No shows the body to have been in 

 life of a yellowish olive above and white beneath, the scales edged with black ; a black 

 streak on each side of the head, passing through the eye ; a vermilion oblique streak 

 along the dorsal and anal, w 7 ith one or two blackish ones ; a blackish vertical streak 

 at the root of the caudal. 



The following are the measurements (in millimetres) of the largest of the twelve 

 specimens brought home by Mr. Loat : —

This dwarfed JBarhcs, remarkable for its large scales, incomplete lateral line, and 

 the absence of barbels, was found only at one place by Mr. Loat, viz. at the mouth of 

 Lake No, White Nile, on February 23rd, 1901.
