Cephalopods collected by bottom trawl at depths of 40,60,80,and 100m from January to July, 1984 off Uyagawa, Shimane Prefecture were examined. Sixteen species plus 2 varieties were identified among which 3 species and l variety were new records to the cephalopod fauna of the Sea of Japan. Sepiidae and Lologinidae were dominant comprising 7 species plus 2 varieties and 4 species, respectively. Together with previous information, over 50 species of cephalopods are known from the Sea of Japan but no endemic species exists. Only 9 species are of cold water origins and the rests are warm water inhabitants. About half of the members are classified into neritic species and closely related with those of the adjacent waters to China. Pelagic species less contribute to the cephalopod fauna of the Sea of Japan compared to that of Pacific side and about half of them are considered to be decaying migrants from the south coming through the Tsushima Straits.
