Four specimens from the Atesu River, Gold Coast, from 

 Mr. 11. B. N. Walker's collection. These specimens have 

 been recorded by Giinther (P. Z. S. 1902, ii. p. 336) under 

 the name of Ainphilius plaft/chir, Gthr., a species which 

 difters in the ventral fins being some way behind the vertical 

 of the dorsal, which is much nearer the end of the snout than 

 the root of the caudal, in the longer snout, and in the shorter 

 barbels. 



Ch iloglanis camcronen si^. 



Body somewhat depressed in front, compressed behind, its 

 depth 4^ to 5 times in the total length. Head depressed, 

 once and ^ as long as broad, its length 3 times in the total 

 length. Eye directed upwards, in second half of head, its 

 diameter 7 or 8 times in length of head, once and § in inter- 

 orbital width, which equals or is a little less than the distance 

 between eye and posterior nostril ; pr;emaxillary teeth in 

 two large oval groups, well separated on the middle line, 

 Ibrming 4 or 5 transverse series ; a group of 12 to 14 

 slender mandibular teeth ; maxillary barbel :^ to ^ length of 

 head, longer than the lower labials. Dorsal I 5 ; spine not 

 serrated, about 2 length of head. Adipose low, its base about 

 ^ its distance from the rayed dorsal. Anal III 5-6. Pectoral 

 spine not serrated, ii to § length of head. Ventral extending to 

 origin of anal or a little beyond. Caudal slightly emarginate. 

 C'audal peduncle once and a half as long as deep. Pale 

 brownish above ; head marbled with dark olive and with a 

 chevron-shaped dark band passing through the eyes, the 

 })oint on the occiput ; three broad dark cross-bands on the 

 body, the first behind the dorsal, the second across the base 

 of the adipose fin, the third at the base of the caudal ; fins 

 whitish, with a dark band across the caudal. 



Total length 50 mm. 



Seven specimens from Efulen^ South Cameroon, collected 

 by Mr. G. L. Bates. 



This species is closely related to C. modjensis, Blgr., 

 recently dcEcribed from Southern Ethiopia, from which it is 

 readily distinguished by the shorter caudal peduncle and tlie 

 wider interspace between the tv>'o groups of prtemaxillary 

 teeth.
