1899.] FROM THE GOLD COAST. 723 



Anal fin reaching the caudal, if laid backward, with 13 rajs, 8 of 

 which are branched. Caudal fin deeply cleft, with the upper lobe 

 at least as long as the head. Pectoral spine (broken) serrated 

 along both edges. Upper parts greyii^h olive, sides and abdomen 

 silvery. 



Seventeen inches long (433 millim.). 



Young (PL XLIL, fig. A.) — The height of the body is contained 

 4| times in the total length (without caudal), the lenrth of the head 

 3| ; caudal peduncle three fifths as high as long. Head as high as 

 broad, its greatest width being equal to the length of the head with- 

 out snout. Granulations on the upper side of the head and form of 

 the nuchal bones as ia the adult. Snout of moderate extent, with 

 the upper profile rather curved ; its length is one third, or a little 

 more than one third, of that of the head ; upper jaw more or less 

 projecting beyond the lower ; mouth of moderate width, wider than 

 the distance between the eyes. Xasal barbels thin, half as long as 

 the eye ; maxillary and outer mandibulary barbels reaching to, or 

 even beyond, the gill-opening, if laid backward ; inner mandibulary 

 barbels distinctly anterior to the outer, and distant from each other 

 about half a diameter of the eye. The teeth on the palate and 

 intermaxillary are placed as in the adidt. The width of the bony 

 interorbital space is scarcely more than half that of the orbit, 

 which is rather less than the length of the snout, and contained 3| 

 times in that of the head. Dorsal fin rather high, reaching to, 

 or nearly reaching to, the adipose, when laid backward ; the length 

 of its base is one half, or a little more than one half, of its distance 

 from the adipose, and exceeds the length of the base of the latter. 

 Dorsal spine serrated along both its edges in its upper portion, 

 and rather shorter than the head. Anal fin reaching or nearly 

 reaching the caudal, if laid backward, with 14 rays, 8 of which are 

 branched. Caudal fin very deeply cleft, both lobes longer than the 

 head. Pectoral spine stronger, but rather shorter than that of 

 the dorsal fin. tipper parts greyish olive ; sides and abdomen 

 silvery. 



PiA^e and six inches long (130 and 155 millim.).

The height of the body is contained 4| times in the total length 

 (without caudal), the length of the head 3^ times ; caudal peduncle 

 two thirds as high as long. Head a little broader than high, its 

 greatest depth being two thirds of its length ; the greater portion 

 of its upper surface is covered with thin soft skin, but the 

 granulated parts of the bones on the nape and crown of the head 

 are exposed or covered with a thin film of skin ; occipital process 

 longer than the basal bone of the dorsal spine, both meeting a little 

 behind the middle of the nape. Snout rather long, depressed, 

 with the upper profile straight, obliquely descending ; its length is
