Sixteen fossil Balanomorpha and one fossil Lepadomorpha were found from Pleistocene coastal terrace deposits at two localities in the southwestern part of Kochi Prefecture, Shikoku. Many of them indicate first fossil records in Japan and the southernmost occurrences in the Pleistocene. The species from the Hirano Formation (Loc. 1) are mainly composed of inhabitants in the upper sublittoral and intertidal zones of an open sea. Most species from the Ashizuri Formation (Loc. 2) are inhabitants in similar zones of an embayment.
