40 EINAR LÖNNBERG. FISHES. 



Barbus jarsinus Blgr. 



Blgr.: Cat. Fresh Water Fish. Afr. II, p. 62. 



Several small specimens from Guaso Nyiri below Chanler Falls agree fully with 

 Boulenger's description of this species, the type-locality of which is Yerrer river of 

 the Webi Shebeli system. 



Barbus luazomelae n. sp. 



Blgr.: Cat. Fresh Water Fish. Afr. II, p. 124. 



Depth of body 3 1 2 to 3 3 i in total length without caudal; length of head about 

 4 times. Snout rounded 1 */» (young) to nearly 2 times as long as eye, which is con- 

 tained from 4 (young) to nearly 6 times in length of head. Interorbital width con- 

 tained about 3 times in length of head. Mouth terminal, lower lip interrupted in 

 the middle. Posterior barbel fully twice as long as eye, even in the young it is much 

 longer than eye, nearly twice. Dorsal III, 7, equally distant from eye and root of 

 caudal, exactly of the same shape as in Boulenger's figure (1. c. p. 124) of B. ser- 

 rifer; last simple ray rather strong, bony, serrated behind, about half the length of 

 the head, or a little more. Anal III, 5, its tip is by far not reaching the caudal. 

 Caudal peduncle ] V2 to 1 Va as long as deep. Scales radiately striated 26 (27); 4 

 between lateral line and origin of dorsal; 3 between lateral line and origin of ventral, 

 12 round caudal peduncle. Olive above, silvery white below with a dark stripe along 

 each side of the body. 



This fish which was found to be common in Luazomela river is evidently closely 

 related to Barbus serrifer which has been described by Boulenger from Tanganyika. 

 The Luazomela fish is, however, very easily and sharply distinguished by its in all 

 stages much smaller eyes. The posterior barbel is long even in the young. The 

 dorsal spine is shorter and the whole fish somewhat more slender. 



Bagrus docmak (Forsk.). 



Blgr.: Cat. Fresh Water Fish. Afr. II, p. 308. 



A specimen from Itiolu river, and three others from Guaso Nyiri from above 

 and below Chanler Falls prove this species to belong to the whole of this river 

 system. One of the specimens from Guaso Nyiri was so large that only skin and 

 head could be preserved. A t Guaso Nyiri we caught this fish on hooks, and used 

 it for food. 



This species appears to be widely distributed to quote Boulenger, from »Nile 

 Delta to Lake Victoria and Shoa tributaries of Blue Nile; Ganana River, Lake Ste- 

 phanie, Omo and Sagan Rivers».
