Photograph of a preserved specimen (scale bar = 1.0 cm). C. EOD waveforms. One EOD was arbitrarily selected from each recorded individual and superimposed with the other recordings (N = number of individuals). All EODs are scaled to the same peak-to-peak voltage, and they are plotted (head-positive up) on the same time scale as overlays centered on the largest positive peak of each waveform (scale bar = 0.2 msec)." httpUri="https://zenodo.org/record/197599/files/figure.png" pageId="30" pageNumber="31">Fig. 10</figureCitation>

A). Body uniformly white-silver with metallic iridescence. Two characteristic melanin markings are present, sometimes with very weak intensity in large individuals: (1) an irregular round mark below the anterior base (first to fourth rays) of the dorsal fin; (2) an ovoid blackish mark, often irregular in shape, centered at the base of the caudal fin and extending onto the upper and lower fleshy lobes of this fin. The fins themselves (caudal fins and others) are translucent.

Exact type localities are unknown for P. b a l a y i and P. sauvagii. Based on our understanding of the chronology of Central African exploration at the time of the descriptions, we estimate these type localities to be the following: the vicinity of Pool Malebo on the Lower Congo River near the modern cities of Brazzaville and Kinshasa [4.25 ° S, 15.29 ° E] for P. sauvagii; and the vicinity of the present-day city Lambaréné on the Lower Ogooué River [0.7 ° S, 10.22 ° E] for P. b a l a y i.
