length of head ; mouth small, inferior ; lips moderate ; two barbels on 

 each side, posterior longer than anterior and as long as or a little longer 

 than eye. Dorsal III 7, equally distant from occiput and from caudal, 

 border straight ; last simple ray not enlarged, not serrated, a little 

 shorter than head. Anal III 5, not reaching caudal. Pectoral a little 

 shorter than head, not reaching ventral ; base of latter wholly or partly 

 anterior to dorsal. Caudal peduncle If times as long as deep. Scales 

 radiately striated, 30-36 gFgf, 3J-4| between lateral line and ventral, 

 12-14 round caudal peduncle. Brown above, whitish beneath, usually 

 with a lateral series of round black spots.

Barbus (Pseudobarbus) pallidus, A. Smith, 111. Zool. S. Afr., Fish, 

 pi. xi. fig. 2 (1840), from "clear streams in various parts of Cape 

 Colony," may be based in part on the preceding fish, but the figure 

 cannot be identified with it, and the description is very unsatisfactory. 

 The figure represents a Barbus 65 millim. long, with the depth of the 

 body 3i times in the total length, the length of the head 4 times ; eye 

 3 times in length of head ; barbels very short. Dorsal witli 7 soft rays, 

 equally distant from anterior border of eye and from caudal, its origin 

 corresponding to that of the ventral. From the figure the scale-formula 

 would be 30 4 ?, 3, 12. Uniform greenish-brown above, white beneath.

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

 much shorter than eye, which is about 3^ times in length of head ; inter- 

 orbital width about 2J times in length of head ; two barbels on each 

 side, posterior longer, about as long as eye. Dorsal III 7, border 

 straight ; last simple ray not enlarged, not serrated, a little shorter than 

 head. Anal III 5. Pectoral not reaching ventral ; base of latter 

 anterior to origin of dorsal. Caudal peduncle nearly twice as long as 

 deep. Scales 30 Vf, 3 between lateral line and ventral. Silvery, with a
