On a collection of fishes from Stanley Pool (Belgian Congo)

From Mr. A. Werner, collector and animal dealer at Munich, Germany, the Leiden Museum received a collection of 1012 well preserved specimens of fishes from Stanley Pool (Léopoldville), Belgian Congo. As several species proved to be new for this locality and are not mentioned in Poll's paper on the fishes from Stanley Pool (1939), the following publication was considered worth while. Moreover, a new Synodontid species, Synodontis werneri, is described. In the present report, the various species are recorded in the same order as in Poll's account. The name of the locality, being always the same, is omitted further on. Protopterus dolloi Boulenger 2 ex., January 1956, 76-91 mm. Both specimens are juvenile and have the tail slightly mutilated. Scales in 90-98 transverse rows between occiput and vent, 42-44 around the body. The rather stout limbs are short, the anterior pair about 4.5 in head, the posterior pair 5/5 and 4/2 in head, the small specimen having the longest posterior limbs. The three external gills are small, 1-1.5 eye-diameter. The distance from origin of dorsal fin to occiput is about 1.5 times the distance to vent. The colouration is wholly dark. Protopterus spec. 57 ex., August 1955, 33-47 mm. These juvenile specimens appear to belong to a second species, but a definite identification seems inadvisable on account of lack of sufficient comparative material. The following data can be given: head 4-4.5 in head and trunk; dorsal
