The height of the body is contained thrice in the total length (without caudal), the length of the head thrice and two thirds. Snout short, shorter than the diameter of the eye, which is one third of the length of the head, and equal to the width of the interorbital space. Maxillary very short, scarcely extending to the front margin of the orbit. Intermaxillary with about nine simply notched teeth on each side; teeth of the lower jaw smaller. The origin of the dorsal fin is midway between the end of the snout and root of the caudal, which is forked. Anal short and low. The root of the ventral is vertically behind the origin of the dorsal. Brownish, with a narrow black band running along the side below the lateral line. Gaboon. Several specimens, from 2 to 2\ inches long, are in the author's possession, and will be deposited in the British Museum. MORMYRUS LEPTURUS. (Plate LXIX. fig. B.) D. 19. A. 24. L. lat. 44. Snout very obtuse, with the mouth terminal, and the upper profile somewhat more curved than the lower; upper jaw slightly overlapping the lower. Eye small, shorter than the snout, situated before the middle of the length of the head. Teeth small, deeply notched, iew in number. Pectoral shorter than the head, extending to the middle of the ventral, which is only half as long. The height of the body is two sevenths of the total length (without caudal), the length of the head two ninths. The caudal peduncle is longer than the head, and very slender, its depth being one third of its length. Brown, head blackish. Two black vertical bands descend from the origin and end of the dorsal fin to the anal. Gaboon. Two specimens, 3 inches long, are in the possession of the author, and will be deposited in the British Museum. BELONE PUNCTULATA. D. 21. A. 21. The free portion of the tail is slightly compressed, rather deeper than broad ; the lateral line terminates in a distinct keel, which is not coloured black. The length of the head is contained twice and four fifths in the total (without caudal) ; a deep median groove runs along the median line of the forehead; crown of the head flat. Maxillary entirely hidden by the praeorbital. The greatest depth of the body is but little less than the length of the postorbital portion of the head. Teeth of moderate size; vomerine teeth none • tongue smooth. The diameter of the eye is two thirds of the width of the interorbital space, and contained twice and two thirds in the length of the postorbital portion of the head. Ventral fin nearly midway between the base of the caudal and the centre of the eye. Posterior dorsal and anal rays shortest, terminating at some distance from the caudal; anterior rays of moderate length. Caudal fin |
