OP FISHES FEOM LAKE TANGANYIKA. 549 



In my first Report I had recorded a Labeo from Lake Tanganyika, on the evidence 

 of a sketch made by Mr. Moore ; but as no specimen had been preserved, the species 

 could not be determined. 



11. Varicorhinus tanganicle Blgr. 



Two specimens from Niamkolo. Native name : Imbara. 



Dr. Cunnington measured a specimen 463 millim. long. " Greenish brown above ; 

 paired fins and anal with a pinkish tinge." 



This is the fish described by me as Capoeta tanganicce. I have since had occasion to 

 show that Capoeta is a synonym of Varicorhinus of Ruppell, which has priority. 



12. Bakbus serrifer Blgr. 



Kituta, in a swamp. Native name : Palala. 



" Olive-green above, shading to silver below ; a red spot on gill-cover immediately 

 behind eye ; blue-black spot at root of caudal ; dorsal and caudal fins with distal third 

 orange ; paired fins and anal yellowish." 



13. Barbus tropidolepis Blgr. 



Niamkolo, Mbete, and Uvira. Native names : Kaluka Matanda, Kitumbi Mbalaga, 

 and Birigi. 



Dr. Cunnington notes that this fish grows to a length of 500 millim., and is often 

 taken in rivers 1 . The colour in fresh specimens is olive above, shading off to silvery 

 or to light brownish-grey and silvery ; paired fins and anal yellowish ; the largest 

 specimen preserved (measuring 290 millim.) had the raised lines on the body of a 

 lighter olive and a red blotch at the tip of the spine of the dorsal fin. A smaller 

 specimen (195 millim.) has a short anterior barbel on one side only. 



14. Barii.ius moorii Blgr. 



Sumbu. Native name : Kiriabakawba. 



The largest specimen measures 160 millim., and has 11 very distinct vertical dark 

 bars on the side. 



15. Neobola iMiMUTA, sp. n. (Plate XXXII. fig. 1.) 



Depth of body 6 times in the total length, length of head 5 times. Snout pointed, 

 not projecting beyond the mouth, shorter than the eye, which is 3-j times in length of 

 head and equals interorbital width ; mouth extending to below anterior border of eye; 

 suborbital bones covering greater part of cheek. Dorsal II 7, originating further back 

 than anal, at equal distance from head and from root of caudal, longest ray about
