 between lateral line and ventral, 12 round caudal peduncle. 

 Bluish olive above, yellowish beneath ; fins dark slate-colour j 

 iris deep yellow. 



Four specimens, measuring 350, 250, 150, and 180 millim. 

 respectively, were obtained in Lake Tsana, the largest at 

 Zegi, May 31, 1902, the three others at Bahardar, June 4,

This species is near B. ned<jia^ Kiipp., from wliich it is 

 distinguished by the lesser development of the lips and the 

 shorter barbels. 



Barhus leptosoma. 



Depth of body 5| to 4^ times in total length, length of 

 head 4 to 4 5 times. Snout rounded, 3t to 3^ times in length 

 of head ; diameter of eye 4 to 4§ times in length of head, 

 interorbital width 31 to 3i times ; mouth inferior, its width 

 4 5 to 5 times in length ot head ; lips moderately developed, 

 continuous across the chin ; barbels two on each side, sub- 

 cqiial, as long as the eye or a little shorter, longer than the 

 distance between them. Dorsal III 8-9, last simple ray very 

 strong, bony, not serrated, straight or slightly curved, as long 

 as or slightly shorter than the head ; free edge of the fin 

 emarginate ; its distance from the occiput less than its dis- 

 tance from the caudal. Anal III 5, longest ray § length of 

 head. Pectoral f to | length of head, not reaching ventral; 

 latter below anterior rays of dorsal. Caudal peduncle twice 

 or nearly twice as long as deep. Scales 30-35 ^^, 3 between 

 lateral line and ventral, 12 round caudal peduncle. Silvery 

 in life, tinged with a vivid blue; the belly and fins whitish, 

 tinged with carneous. 



Three specimens, two measuring 225 millim., the third IGO, 

 from Zegi, Lake Tsana, May 18 and 19, 1902. 



Distinguished from B. breviharbis by the more elongate 

 form, the shorter head, the thinner lips, and the longer spine 

 of the dorsal fin. 



Barhus oreas. 



Depth of body equal to length of head, 4 times in total 

 length. Snout rounded, 3 times in length of head; diameter 

 of eye 4^ to 5 times in length of head, interorbital width 3 

 times ; mouth inferior, its width 4 times in length of head ; 

 lips much developed, the lower forming a short rounded median 

 lobe; baibels two on each side, anterior slightly longer than 

 eye, posterior 1:|^ to 1.'. as long as eye, the distance Letweeu
