Fifteen species of verbeekinid and neoschwagerinid fusulinaceans are dis- criminated from the Akiyoshi Limestone Group below the Misellina (M.) claudiae Zone in the Kaerimizu area. Among them, Misellina (Brevaxina) nipponica, sp. nov., M. (M.) postclalldiae, sp. nov. and M. (M.)? ventricosa, sp. nov. are new to science. Stratigraphic distribution of the early representatives of verbeekinid and neoschwagerinid fusulinaceans, besides their ancestral forms, makes it possible to establish 10 fusulinacean biohorizons in the stratigraphic interval between the first occurrence of Pamirina (Levenia) leveni and that of Parafllslliina kaerimizensis. Of them, three biohorizons, which are well recognized in the surveyed area, define the base of the Pamirina (Levenia) leveni, Misellina (Brevaxina) dyhrenfllrthi olai and Misellina (M.) clalldiae Zones established herein. Biostratigraphic evidence observed in the Akiyoshi Limestone Group provides many important data concern- ing the origin and early evolution of the families Verbeekinidae and Neoschwagerinidae.
