not known to surpass 56 mm SL. Morphometric ratios and meristics presented in Table 1. Body depth and width as proportions of SL are in middle range for species of this genus. In all but gravid females, depth at origin of anal fin equal to or slightly less than depth at mid-body. Greatest width at opercles. Dorsal and ventral profiles gently convex. The head profile is slightly convex above the eye, the snout is rounded to somewhat truncate and projects slightly beyond the mouth. Mouth small. No submental swelling. Eye small, covered by epidermis. Inter-orbital distance is 72-90% of head width. Nostrils well separated with posterior nostril located near rictus of mouth. Teeth 7-8/8-9, usually 7/8, bicuspid. Head (including eye), upper back and belly covered by epidermis that is translucent in life, semi-opaque in preservation. When pressed to side, tip of pectoral fin extends well past origin of pelvic fin. Pectoral fin has 8 or 9 rays. Dorsal and anal fins roughly symmetrical above and below body axis, the anal fin (of 19-21 rays) slightly longer, with the dorsal fin (of 14-17 rays) originating at vertical through the origin of the fourth or fifth anal fin ray; the origins of the last dorsal and last anal fin rays at roughly the same vertical. Lobes of caudal fin short, very rounded and blunt. Caudal peduncle relatively short (14-16.5% of SL), of moderate depth (37-45% of length), with 12 circumpeduncular scales. First 22-28 scales along lateral line bearing pores, last pore-bearing scale lying past vertical through origin of anal fin. Total scales along longitudinal line 44-50. Scale rows between origin of pelvic fin and lateral line scale 11 to 13. Total vertebrae 36 (excluding urostyle).

The species is usually taken along the margin of small forest streams (Fig. 4) in root tangle where it occurs with other species of mormyrids, but has also been taken along the margin of the Ivindo River proper in deep water. Individuals are often found spaced apart at intervals of 50 cm to one meter. Diet of this species has not been studied, but is probably similar to that reported for

has a 110 to 720 microsecond duration EOD waveform with three to four peaks in the discharge (Fig. 5A-F). The EOD begins with a small head-negative phase or peak, P0, followed by a larger head-positive phase, P1, followed by the largest head-negative peak, P2. In some fish, the discharge ends with a final head-positive phase, P3. The peak spectral frequency of the Fourier Transform of the EOD is between 4000 Hz and 16,000 Hz. Average peak heights, total durations, and spectral peak frequencies for this species, are listed in Table 2. The EOD is sexually dimorphic among sexually mature individuals. Juvenile male EODs are similar to female EODs. Male EODs are longer in duration and have lower FFT peaks than females. They also differ in the heights of peaks P0 and P1 relative to the full peak to peak height compared to females (Table 2). The EOD of a juvenile of this species was reported by Heymer &amp; Harder (1975).
