XLVIII. — Description of a new Barbus/rom Natal. 

 By G. A. BOULENGER, F.R.S. 



1 wo species have been confounded in the original description 

 of Barhus Gurneyi, Giiiither, Cat. Fish. vii'. p. 102. The 

 character of the small eye " its diameter heing one-ffth of the 

 length of the head in specimens only ?>\ inches long,^^ having 

 been specially emphasized by tiie describer, it seems to me 

 the proper course to restrict the name chosen by him to the 

 smaller specimens, and to propose a new name for the larger 

 ones which were believed to represent the adult condition. 

 In doing this 1 have great pleasure in connecting the name 

 of Col. Bowker with the fish of which he presented a young 

 individual to the Britisii Museum a few years ago, as it is 

 through this that I was Hr.-~t able to detect the error which 

 is here corrected. 



Barhus Boukeri. 



Depth of body nearly equal to length of head, 3| to 4^ 

 times in total length. Snout rounded, about ^ length of 

 head ; diameter of eye 4^ (half-grown specimen) to 5^ times 

 in length of head, 1^ to twice in interocular width ; width 

 of mouth more than half that of head ; li|)S tliick ; two pairs 

 of barbels, the posterior a little longer than the anterior and 

 as long as or slightly longer than the eye. Dorsal ill 8-9, 

 equally distant from occiput and root of caudal, its border 

 slightly concave; third ray feeble, smooth; longest ray ^ to 

 §- length of head. Anal II 5; longest ray 'f^ to f length 

 of head, reaching or nearly reaching root of caudal.

 which is inserted under the first rays of the dorsal. Caudal
