22. Barhus Uptosoma, Blgr. — Jujii River.

Depth of body 3| times in total length, length of head 3i 

 to 4 times. Snout rounded, 3 to 3^ times in length of head ; 

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

 times ; mouth inferior, its vvidtli 3§ to 5 times in length of 

 liead ; lips well developed, the lower continuous across the 

 chin and forming a small rounded median lobe; barbels two 

 on each side, anterior a little longer than eye, posterior once 

 and ^ to once and ^ length of eye. Dorsal IV 9, free edge 

 emarginate ; last simple ray very strong, bony, not serrated, 

 nearly straight, | to f length of head. Anal III 5. Pectoral 

 a little shorter tiian head. Ventral below anterior rays of 

 dorsal. Caudal peduncle once and ^ to once and § as long as 

 deep. Scales 28-30 ^f, 2^ between lateral line and ventral, 

 12 round caudal peduncle. Dark olive above, silvery white 

 beneath. 



Total length 265 mm. 



Two specimens from the Gudar River and two from the 

 Metti River, affluent of the Gudar River. 



Near B. areas, Blgr. ; distinguished by the lower number 

 of scales in the lateral line. 



24. Barhus Duchesnii, Blgr. — Ergino River, Sagan River, 



Elgo River, Ganda River. 



25. Barhus affinis, Riipp. — Didessa River, Zeissi River, Elgo

* This species was founded on a badly preserved dry specimen from 

 Lake Ganjule. It proves to be closely allied to B. hynni, differing in 

 having only 2h series of scales between the lateral line and the ventrals. 

 The spine of the dorsal fin is remarkably strong and much longer than 

 the head. 



t U. NeuviUii, Pellegr., is probably identical with this species.
