A number of specimens of Hexapus sexpes (Fabricius) have been obtained by the writer from the waste of the trawl-net in Mikawa District, Aichi Prefecture. These speimens are enormous in size compared with those hitherto recorded by the previous authors (cf. page 49). The biggest female specimen measured 19.5 mm in the length of carapace and 33.0 mm in the width of same. According to Dr. T. SAKAI, such big specimens of Hexapus sexpes are not uncommon in Suruga Bay (off Numazu City) and Sagami Bay (off Enoshima). The literatures and references of this species, as well as the congeners are enumerated in the Japanese text of this paper.
