Eight fossil molluscan species, including Cryptopecten yanagawaensis (Nomura and Zinbo) and Turbo (Marmarostoma) mekamiensis Nishiwada, are described on the basis of material obtained from the late Early to early Middle Miocene Megami and Ebie limestones in the Sagara district, Shizuoka Prefecture, Japan. Cryptopecten yanagawaensis has been recorded from late Early to early Middle Miocene formations in Japan. The occurrence of this species indicates that the reef limestones in the Megami Formation were formed within the Japanese faunal realm in Miocene time. In this paper some comments are made on the origin and sedimentary environments of the limestones in the Megami Formation.
