Dr. Spurrell, who for some years has enriched our collection of 

 livmg animals with many examples of Reptiles from the Gold 

 Coast, has lately turned his attention to Fishes, and has presented 

 two small collections to the British Museum. Among them I 

 have found examples of what appear to me three new species. 

 These fishes are from the vicinity of Bibianaha, near Dunkwa, 

 between the watersheds of the Tano and Ankobra Rivers. Notes 

 on the fresh coloration have been supplied by Dr. Spurrell. 



Barbus spurrelli, sp. n. (PI. III. fig. 1.) 



Depth of body 3 to 3| times in total length, length of head 3g to 

 3| times. Snout rounded, as long as eye, 3^ to 3| times in length 

 of head, interorbital width 2| to 3 times ; mouth subinferior ; 

 lips moderately developed ; two barbels on each side, posterior as 

 long as eye and twice as long as anterior. Dorsal III 8, equally 

 distant from centre or anterior border of eye and from root of 

 caudal, border feebly concave ; last simple ray not enlarged, as 

 long as head. Anal III 5, not reaching caudal. Pectoral 4 length 

 of head, reaching ventral ; base of latter below anterior rays of 

 dorsal. Caudal peduncle 1 to Ij times as long as deep. Scales 

 radiately striated, 24-26 ^? 2 between lateral line and ventral, 

 10 or 12 round caudal peduncle. Greenish silvery, darker on the 

 back, the scales dark-edged or with a dark base ; this dark base 

 often more marked on the scales of the lateral line, which may be 

 further obscured by black dots, forming an ill-defined dark 

 lateral band ; fins greyish. 



Total length 75 mm. 



Several specimens. 



This species comes very close to B. ahlabes Blkr. 



Barilius macrostoma, sp. n. (PI. III. figs. 2, 2 a.) 



Depth of body equal to length of head, 3| times in total length.
