Campylomormyrus numenius (Boulenger, 1898)
Original Published Description:
From Boulenger 1909, pp. 124-125.
Depth of body 4 2/3 to 5 times in total length, length of head 2 2/5 to 2 1/2 times. Upper profile of head convex; snout produced into an extremely long, compressed tube, feebly curved downwards, its length, in the adult, 5 to 5½ times postocular part of head, and 20 times its least depth, which equals diameter of eye; latter 2/3 interorbital width; lower jaw with a compressed dermal appendage nearly as long as eye; teeth conical, 7 in upper jaw, 4 or 6 in lower. Dorsal 27-34, originating above 8th or 9th ray of anal, its length 1 2/3 to 1 3/4 times in its distance from head. Anal 29-37, equally distant from base of ventral and from base of caudal. Pectoral pointed, less than 1/2 length of head, almost twice as long as ventral, and extending almost to extremity of latter. Caudal scaled with obtusely pointed lobes. Caudal peduncle 3 times as long as deep, 1/3 to 1/2 length of head. 76-81 scales in lateral line, 15-18 / 24-25 transverse series on body, 16-19 / 15-18 in transverse series between dorsal and anal, 16 round caudal peduncle. Pale brownish above, whitish beneath.
Distinguished from Campylomormyrus curvirostris, another very long-snouted species by having a feebly curved (versus strongly curved in C. curvirostris) snout, with its depth approx. 5% of its length (versus more than 8%), and a shorter caudal peduncle (3x as long as deep versus 4x). Lobes of caudal fin are obtusely pointed in C. numenius, while more distinctly pointed in C. curvirostris. (from Boulenger 1909.)
