Abstract

Among the gastropod specimens trawled from bathyal depths (450-780m) 18 species were identified. Four species, namely, Eosipho tosaensis, Neptunea kotakamaruae, Antiplanes delicatus, and Spergo nipponensis are recognized to be new species. Morphological characters, particularly radula, and distributions of "rare" species, e.g. Otukaia kiheiziebisu, Orectospira tectiformis, Trophonopsis soyoae, Buccinum koshikinum, Ptychosirynx bisinuata japonica among others are discussed. Bathyal gastropod fauna in Tosa Bay seems to represent a mixture of faunulae of intermediate (slope) water and undercurrent.
