Thirty-seven species belonging to 16 genera of fusulinaceans are discriminated from the Akuda and Horikoshitoge Formations, exposed in Hachiman town, Gifu Prefecture, Central Japan. Among them, the following six species are newly proposed : Sphaerulina akudensis, Dunbarula uenoi, Schwagerina shukoae, S. kanumai, Pseudofusulina minoensis, and P. miyamensis. This fusulinacean fauna is similar in composition to that described from the Nyukawa Group exposed about 60km northeast of the present area, and indicates the Yakhtashian to Kubergandian of the standard stratigraphic scheme of the Tethyan Province.
