" The material described below was collected in the Malagarasi river and swamps by members of the East African Fisheries Research Organization (later the East African Freshwater Fisheries Research Organization) during a survey of the area carried out in August and September 1952. Details of the habitats from which specimens were obtained are given in Greenwood (1954:401-402). The new taxon brings the total number of cichlid species recorded from the upper part of the Malagarasi system to six, of which five (the new species, Astatoreochromis vanderhorsti [Greenwood], Orthochromis malagaraziensis [David], Sarotherodon karomo [Poli], and Serranochromis janus Trewavas) are endemic; the sixth species, provisionally identifled as Astatotilapia bloyeti (Sauv.), belongs to a poorly understood complex of taxa. It may well be specifically distinct from the type and other populations of A. bloyeti, and thus would also have to be considered an endemic of the Malagarasi system (see Greenwood, 1954, & 1979:283-286, 297-298 and 302-303).
