])ca(l, veacliiiig or nearly reaching root of caudal. Pectoral 

 as long as or a little shorter than head, not reaching ventral ; 

 latter a little posterior to origin of dorsal. Caudal peduncle 

 ] I to If as long as deep. Scales 33 5?, 3 between lateral 

 line and ventral, 12 or 14 round caudal peduncle. Silvery, 

 darker on the back ; pectoral and ventral fins flesh-coloured ; 

 iris nearly white, witli a fine yellow ring round the pupil. 



Total length 220 miUim. 



Three specimens of nearly the same size, one from the 

 Gota River at Marmusa, Jan. 21, 1902, and two from the 

 Kassam River at Awhorra j\lullka in Shoa, altitude about 

 4000 feet, Feb. 7, 1902. 



Like the recently described B. perplexicnns from the Tana 

 system, this fish might be referred to the genus Capoela as 

 defined by Giinther"; but this, it seems to me, would be in 

 violation of the natural affinities, which are with B. inter- 

 medins, Riipp., just as tiiose of B. perpJexicaiis, Blgr., are 

 with B. fanensis, Gthr., and B. Hindii, Blgr. Nevertheless, 

 Barbus plagiostomus evidently constitutes a connecting-link 

 between B. intermedins and Varicorhinus heso of Ruppell. 



Barbus j^latijstomus. 



Depth of body 3 1 to 3| times in total length, length of 

 bead 4 to 4^ times. Snout very broad, rounded, not quite ^ 

 length of head ; diameter of eye 5 to 5^ times in length of 

 head, interorbital width 2| to 3 times ; mouth large, terminal, 

 its width 3 times in length of head ; lips moderately deve- 

 loped, interrupted on the chin ; barbels two on each side, 

 anterior as long as the eye, |X)sterior 1^^ to 1| diameters of eye, 

 the space between them as long as the eye. Dorsal IV 8-9, 

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

 I to f- length 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 | to # length of head, reaching or 

 nearly reaching root of caudal. Pectoral | to | length of 

 head, not reaching ventral ; latter a little posterior to origin 

 of dorsal. Caudal peduncle If as long as deep. Scales
