(Plate XLVIL fig. 1.) 



Boulenger, Ann. & Mag. N. H. (7) x. 1902, p. 436. 



Depth of body equal to the length of the head, four times in the total length. 

 Snout rounded, four and a half times in the length of the head ; diameter of eye three 

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

 mouth terminal, its width four and a half times in the length of the head ; lips feebly 

 developed ; barbels two on each side, the anterior barely half the diameter of the eye 

 and longer than its distance from the posterior, which measures nearly three-fourths 

 the diameter of the eye. Dorsal fin with III 7 rays, last simple ray bony, strongly 

 serrated behind, three-fourths the length of the head ; free edge of the fin not 

 emarginate; its distance from the occiput a little less than its distance from the 

 caudal fin. Anal fin with III 5 rays, longest three-fifths the length of the head. 

 Pectoral fin two-thirds the length of the head, not reaching the ventral ; latter below 

 anterior rays of dorsal. Caudal fin deeply forked. Caudal peduncle twice as long as 

 deep. Scales with fan-shaped striation, 35 p, 3 between lateral line series and 

 ventral, 16 round caudal peduncle ; the lateral line reduced to its anterior portion 

 (5 to 8 tubules). 



Silvery, brownish on the back ; a black line along each side of the body ; fins greyish. 



Total length 40 millim.

Three specimens were obtained by Mr. Degen at Bahardar, Lake Tsana, on June 4, 

 1902, and one in the Unfras River, Lake Tsana, May 9, 1902. 



This species stands near the preceding, from which it is easily distinguished by the 

 position of the ventral fins below the dorsal and the incomplete lateral line.
