Fishes from the Kyong River, S. Cameroon. G9 



Total length 200 mm. 

 A single specimen. 



Distinguished from A. hallayi, Sauv., by the longer, 

 narrower head. 



Synodontis steindachneri. 



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

 3^ times. Head 1£ times as long as broad, rugose above 

 behind snout, which is obtusely pointed and as long as post- 

 ocular part of head ; eye supero-lateral, 5 times in length of 

 head, If times in interorbital width; lips moderately deve- 

 loped ; prsemaxillary teetli forming a short and broad band ; 

 movable mandibular teeth § diameter of eye, 25 in number. 

 Maxillary barbel with a broad marginal membrane at base, 

 as long as head, reaching a little beyond base of pectoral 

 spine ; outer mandibular barbel about twice as long as inner,

 branches. Gill-openings not extending downwards beyond

 long as head, feebly curved, striated, with feebly retrorse 

 serrge in front in its upper part, strongly serrated behind.

This species, named in honour of Dr. Steindachner, who 

 has quite recently contributed to our knowledge of the 

 fishes of Cameroon, is allied to S. obesus, Blgr., and S. robbi- 

 anus, J. A. Smith, but distinguished from both by the 

 shorter maxillary barbel and the shorter adipose fin. 



Pelm atoch rom is ca udifascia tus. 



Depth of body nearly equal to length of head, 3 to 3£ 

 times in total length. Head twice as long as broad ; snout 

 rounded, with convex upper profile, a little broader than long, 

 as long as or slightly longer than eye, which is 3£ to 3£
