Show 1902.] FISHES FROM THE GOLD COAST. 337 a free central portion. Anterior dorsal rather long, with more than seven rays and with a pungent spine; adipose fin low and long; ventrals six-rayed, below the posterior third of the dorsal. N o to g l a n id ium w a l k e r i , sp. n. (Plate XXXII.) D. 1/14-15. A. 12. P. 1/7. V. 6. Body moderately elongate, of nearly the same depth in its whole length, the tail being strongly compressed. Head depressed, much broader than deep, two-sevenths of the total length (without caudal); the very small eye entirely in the anterior half of the head ; snout broad, depressed, two fifths of the length of the head, nearly twice as long as the interorbital space is long. Mouth anterior, with the upper jaw rather larger, surrounded by fleshy lips; all the barbels are rather thick near their base: the maxillary extending to the middle of the operculum, the outer mandibulary to the base of the pectoral fin ; the inner mandibulary rather shorter than the maxillary. The maxillary patch of teeth is single, oblong, small, but wider than long; the mandibulary patches separated in the middle, smaller than, but similar in outline to, the maxillary. Pectoral fins short, not longer than ventral, with a strong spine, which, however, is enveloped in thick skin, only its point being free. Dorsal fin very low, only about half as high as the body, with a singularly short spine, not quite half as long as the snout. Adipose fin long, low, commencing shortly behind the dorsal and subcontinuous with the caudal. Caudal rounded. Reddish-brown, darker on the back, body, dorsal and caudal fins, with scattered round black spots, the spots on the caudal fin being the more numerous and smaller. Total length 122 millim. Two specimens from the River Ibbi (Apollonia). S yn o d o n t is r o b b ia n u s J. A. Smith. Several young specimens (3-6 in. long) from the R. Offim. On comparing these specimens with the single young specimen of S. robbianus, I find that they have the interorbital space a little broader than the Old Calabar fish. This does not seem to me to constitute a distinctive specific character. M a l a p t e r u r u s e lec tr icu s L . A young specimen from the R. Oflim. B a r b u s c am p t a c a n th u s Bleek. Many specimens were collected at Infoan, at the town of Akropon, and on the River Atesu. B a r b u s t r is p ilu s Bleek. Many specimens from Infoan, Akropon, and Ingogosu, a village in the mining centre of Kinkiankwa. P roc. Z ool. Soc.- 1902, V ol. II. No. XXII. 22 |
