488 On new FisJies from Central Africa. 



Caudal peduncle as long as deep. Scales 29-30 3I, 2 between 

 lateral line and ventral. No markings, except a silvery 

 lateral band, which is black-edged above.

Two specimens from the Aruwimi, in the Congo Forest, 

 form part of the collection made by Mr. R. B. Woosnam and 

 presented to the British Museum by the Subscribers to the 

 Ruwenzori Expedition Fund. 



In its dentition this new species stands nearest to 

 P. occidentalism Gthr., in which the body is much shorter and 

 the lateral line incomplete. 



Barhus Johnstonii. 



Depth of body equal to l^gth of head, 4 times in total 

 length. Snout rounded, a little longer than the eye, the 

 diameter of which is 4^ times in length of head ; interorbital 

 width 2^ times in length of head ; mouth inferior, its width 

 3 times in length of head ; lower jaw with a blunt edge, 

 covered by a thin horny sheath ; lips feebly developed, lower 

 confined to the sides ; barbels two on each side, posterior 

 slightly longer than the anterior and as long as the eye. 

 Dorsal IV 9, last simple ray flexible, not enlarged, as long- 

 as head ; free edge of tin deeply concave ; its distance from 

 centre of eye equals its distance from caudal fin. Anal III 5, 

 longest ray f length of head. Pectoral slightly shorter than 

 head, not reaching ventral ; latter below middle of dorsal. 

 Caudal peduncle once and f as long as deep. Scales 38 ||

 Kondowe and Karonga, was presented by Sir Harry Johnston

B. rhodesianus, Blgr., which has a similar mouth (ap- 

 proaching the Capoeia type), is distinguished by its larger 

 scales (30-32 p) and its shorter barbels. 



AmpMUus Hargeri. 



Depth of body h\ times in total length, length of head 3| 

 times. Head slightly longer than broad ; eyes small, in the 

 middle of the length of the head, 3 diameters apart; inter- 

 orbital width I length of snout ; latter broadly rounded, 

 projecting but slightly beyond lower jaw; posterior nostril
