Total length 120 millim. 
Several specimens from the Kribi River and from Efulen. 
Allied to B. camptacanthus Blkr. and B. potamogalis Cope. 
Differs from both in the stronger third simple dorsal ray, the 
more numerous scales in the lateral line (24-27 instead of 21-24), 
and the coloration. From the first in the longer posterior barbel, 
from the second in the longer barbels, the smaller eye, and the 
broader interorbital region. 
15. BarBus BATESI, sp. n. (Plate III. fig. 2.) 
Depth of body equal to length of head, 33 times in total length. 
Snout rounded, 3 times in length of head; diameter of eye 5 
times in length of head, interorbital width 3 times ; mouth 
inferior, its width 4 times in length of head ; lips well-developed, 
lower continuous; barbels two on each side, subequal, nearly 
twice as long as eye, the distance between them half their length. 
Dorsal IV 8, last simple ray strong, bony, not serrated, slightly 
curved, 2 length of head; free edge of the fin emarginate ; its 
distance from the occiput less than its distance from the caudal. 
Anal IIL 5, longest ray 3 length of head. Pectoral # length of head,
