Eiipp. Distlnguislied from the latter by the much hroader 

 snout and the broader interorbital region. The lower pha- 

 ryngeal bones are relatively small, as in B. Harriagtoni^ from 

 which they do not differ in the dentition. 



Barhus hassamensis. 



Depth of body 3^ times in total length, length of head 4 

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

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

 times ; mouth inferior, its width \ length of head ; lips 

 moderately developed, lower continuous across the chin but 

 not produced into a lobe ; barbels two on each side, ante- 

 rior 1^ diameters of eye, posterior 1|, the distance between 

 them I diameter of eye. Dorsal IV 8, last simple ray very 

 strong, bony, not serrated, as long as the head ; free edge of 

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

 distance from the caudal. Anal III 5, longest ray a little 

 shorter than head and reaching root of caudal. Pectoral as 

 long as head, nearly reaching ventral ; latter below anterior 

 rays of dorsal. Caudal peduncle 1^ as long as deep. Scales 

 30 ^, 3 between lateral line and ventral, 12 round caudal 

 peduncle. Olive-brown above (in spirit), the scales edged 

 with darker, yellowish beneath ; fins greenish yellow. 



Total length 225 millim. 



A single specimen from the Kassam River at Awhorra 

 MuUka, Shoa, altitude about 4000 feet. 



Very closely allied to B. hynni^ Forsk. Distinguished by 

 a less prominent snout, less developed lips, longer barbels, 

 and a less deep body. 



Barhus hreviharhis. 



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

 head 3i to 3^ times. Snout rounded, 3 times in length of 

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

 head, interorbital width 35- to 3| times ; mouth interior, its 

 width 4| times in length of head; lips much developed, the 

 lower forming a short rounded lobe in the middle ; barbels 

 two on each side, the anterior f to | diameter of eye^ the 

 posterior as long as eye and as long as or a little longer tiian 

 its distance from the anterior. Dorsal IV 9, last simple ray 

 very strong, bony, not serrated, straight or very slightly 

 curved, § to | length of head ; free edge of the fin emar- 

 ginate; Its distance from the occiput equal to or a little less 

 than its distance from the caudal. Anal III 5, longest ray | 

 length of head. Pectoral about § length of head, not reaching
