Barhus macronema. 



Depth of body 3^ to 3f times in total length, length of 

 head o^ to 4 times. Snout rounded, 3j to3g- times in length 

 of head ; diameter of eje 6 to 6^ times in length of liead, 

 interorbital width 2f to 3 times ; mouth inferior, its width 3|- 

 to 4 times in length of head ; lips well developed, the lower 

 with a very short, rounded or truncate median lobe; barbels 

 two on each side, nearly equal, 2 to 2^ diameters of eye, If 

 to 2^ as long as the distance between them. Dorsal IV 8, 

 last simple ray strong, bony, not serrated, feebly curved, 

 about I length of head ; free edge of the fin emarginate ; its 

 distance from the occiput equal to or a little less than its 

 distance from the caudal. Anal III 5, longest ray | to f 

 length of head, reaching root of caudal, or a little beyond. 

 Pectoral f to ^ length of head, not reaching ventral; latter 

 below origin of dorsal. Caudal peduncle 1^ as long as deep. 

 Scales 32-37 \l, 4 between lateral line and ventral, 12 or 14 

 round caudal peduncle. Olive above^ yellowish beneath ; 

 fins greyish. 



Five specimens measuring 260 to 3G5 millim. : one was 

 obtained at Gafersa, in the Maki Kiver, altitude about 

 5000 feet, March 11, 1902; two were procured together at 

 Dedota, altitude about 5500 feet, in the Hawash River, 

 March 16, 1902 ; and two are from the Hurso River, a fast- 

 running mountain-stream flowing northwards in the Upper 

 Adal country, altitude about 7000 feet, Jan. 17, 1902. 



This species has much in common with B. Gregorii^ I^lg''-j 

 but differs in the longer barbels and the presence of four 

 series of scales between the lateral line and tlie ventral fins. 



Barhus UueppcUi. 



Depth of body equal to lengtli of head, 3^ to 3:i times in 

 total length. ISnout broad, rounded, 3 or 3;^ times in length 

 of head ; diameter of eye 4^ (young) to 6^ tunes in length of 

 head, interorbital width 3 to Og- times ; mouth inferior, its 

 width 4 times in length of head ; lips broad, coi\tinued across 

 the chin, but not forming a median lobe ; barbels two on each 

 side, anterior 1^ to 1| diameters of eye, posterior If to 2, the 

 distance between them equal to or a little exceeding diameter 

 of eye. Dorsal IV 8, last sim[)le ray strong, bony, not 

 serrated, feebly curved, | to § lengtli of head; free edge of 

 the fin emarginate ; its distance from the occiput less than its 

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

 of head, reaching root of caudal or a little beyond. Pectoral
