The middle of the Neogene Taishu Group, distributed in Tsushima Islands, Nagasaki Prefecture, the southwest Japan, is considered to include the authigenic carbonates originated from cold-seep and the chemosynthetic molluscan faunas deposited in deep sea environment of greater than 500 m depth. In this study, the author examined classification of the bivalves occurred in the middle of the Taishu Group. Consequently, the molluscan faunas are assigned into the following ten species belonging to seven genera: Bathymodiolus sp., Adipicola sp., Calyptogena spp., Acharax spp., Acila sp., Nuculana sp., and Yoldia sp.
