brou«rlit home iVom Feniaiulo Po by Mr. Seiimuul, arc of a 

 daik olive-green above, sliudiii;^" to ffolden on the sides, and 

 white beneath ; scales of the sides dark at the base, most of 

 those of the lateral line with a black spot at the base ; a more 

 or less distinct dark lateral stri|)e, usually expanding and 

 more intensely black in front and on the caudal peduncle > 

 all the fins, vertical and paired, bright vermilion. 



Small nuptial pearl-like tubercles on the side of the head. 



Total length 155 mm. 



The types of this species are from Fernando Po. I have 

 examined numerous specimens from that island, and others 

 from the Benito River, Gaboon district, and the Kribi and 

 J a liivers, S. Cameroon. 



Barhus tceniurus. 



Barhis ((enixrus, Boiilenger, P. Z. S. 1903, i. p. '2-i, pi. ii. fig. 2, 



Depth of body 3^ to 3^ times in total length, length of 

 head 3^ to 4 times. Snout rounded, 3i to -i times in length 

 of head; diameter of eye 4 to 4. \ times in length of head, 

 interorbital width 2^ to 2^ times; mouth inferior, its width 

 3 to 3^ times in length of head ; lips moderately developed, 

 interrupted on the chin ; barbels two on each side, anterior li 

 to If, posterior longer, 1| to 2 diameters of eye, the distance 

 between them equal to diameter of eye. Dorsal 111 8, last 

 simple ray ossi6ed and moderately strong, but much thicker 

 than the first branched ray, as long as or a little shorter than 

 head; free edge of the fin emarginate ; its distance from the 

 occiput much less than its distance from the caudal. 

 Anal III 5, longest ray 5 to | lei^gtli of head. Pectoral | to 

 I length of head, not reaching ventral ; latter a little posterior 

 to origin of dorsal. Caudal peduncle 1^ to 2 times as long- 

 as deep. Scales 24-27 -^g^, 2^-3 between lateral line and 

 ventral, 12 round caudal peduncle. Olive-brown above (in 

 spirit), yellow on the sides and below; a series of black dots 

 on the lateral line, and a black band on each side of the 

 caudal peduncle; fins white. 



Small nuptial pearl-like tubercles on the side of the head. 



Total length 120 mm. 



South Cameroon (Efulen, Kribi River). 



Very closely allied to JJ. camjjtacanthus, some specimens 

 of which it resembles exactly in coloration. Differs in the 

 usually more slender form, the longer posterior barbel, and 

 the thicker last simple ray of the dorsal tin.
