More new fishes from the Kasai District of the Belgian Congo

A number of small fishes collected in 1932 by Callewaert, at Luluabourg in the Kasai District of the Belgian Congo, were overlooked when the remainder of his collection made at that time was studied and reported on. Their examination, just completed, adds 20 forms to the 42 from the locality previously enumerated in The American Museum of Natural History's collections: namely, 5 mormyrids, 4 characins, 2 cyprinids of which 1 is a Barbus, 5 catfishes, 3 cichlids, 1 Anabas. Our complete collections from the locality now number, 62 species: in percentages, 21 mormyrids, 14 1/2 characins, 35 catfishes, 5 Barbus, 6 1/2  cichlids, and 18 otherwise distributed; characins, catfishes and cichlids being somewhat closer to figures for the Congo than were those reported for the incomplete Luluabourg collections in 1933. The following new species are included: Marcusenius maculipinnis, Heterobranchus platycephaius, Euchilichthys boulengeri, and Steatocranus nelongatus.
