1902.] FISHES FROM EAST AFRICA. 223 



5. Barbus (Capoeta) perplexicans, sp. n. (Plate XYI. fig. 2.) 

 Depth of body 3 times in total length, length of head 4 times. 



Snout rounded, slightly concave in front of the nostrils, feebly 

 projecting beyond the mouth, 1| as long as the eye, the diameter 

 of which is 4 times in the length of the head and If in the inter- 

 ocular width ; width of mouth about half that of the head ; lips 

 feebly developed ; lower jaw with a strong, transverse, horny 

 cutting-edge ; two pairs of barbels, subequal, and as long as 

 the eye. Dorsal IV 10, fourth ray very strong, straight, bony, 

 not serrated, as long as the head ; the fin is notched and 

 originates slightly in advance of the vertical of the first ray of 

 the ventral, a little nearer the end of the snout than the root 

 of the caudal. Anal III 5 ; longest ray ^ the length of the head 

 a;nd narrowly separated from the root of the caudal. Pectoral 

 pointed, nearly as long as the head, narrowly separated from the 

 ventral. Caudal deeply forked. Caudal peduncle 1| as long as 

 deep. Scales 26-30 ^, 2 between the lateral line and the root of 

 the ventral. Olive-brown above, silvery below ; fins whitish. 



Total length 175 miUim. 



Two specimens. 



Although unquestionably referable to the genus Gafoeta, as 

 defined by Giinther, this species is so closely related to the 

 preceding that I have felt some hesitation in separating it. 

 However it difiers, in addition to having a cutting horny edge 

 on the lower jaw, in the shape of the snout, the shorter posterior 

 barbel, and the origin of the dorsal fin slightly more anterior. 



6. Barbus (Labeobarbus) LABiATus, sp. n. (Plate XYII. fig. 1.) 

 Depth of body a little greater than length of head, 3^ times in 



total length. Snout obtusely pointed, not projecting beyond the 

 mouth, twice as long as the eye, the diameter of which is 5| times 

 in the length of the head and twice in the interocular width ; width 

 of the mouth about half that of the head ; lips extremely developed, 

 each produced into a long triangular flap ; two pairs of barbels, the 

 first as long as the eye, the second slightly longer. Dorsal IV 9 ; 

 fourth ray very strong, curved, bony, not serrated, | the length 

 of the head ; the fin is notched and originates above the first rays 

 of the ventral, at equal distance from the nostrils and the root of 

 the caudal. Anal III 5 ; longest ray | the leng-th of the head 

 and narrowly separated from the root of the caudal. Pectoral 

 pointed, nearly as long as the head, reaching the base of the 

 ventral. Caudal deeply foi-ked. Caudal peduncle 1| as long as 

 deep. Scales 28-29 ^^, 2 between the lateral line and the root 

 of the ventral. Dark olive-brown above, whitish beneath ; fins 

 grey. 



Total length 270 millim. 



A single specimen. 



The larger scales and the longer pectoral fin distinguish this 

 fish from the one referred by Giinther to B. intermedius of RiippeU,
