Faunal surveys of Mishima Island and two islets of Rokuto Islands (Oshima Island and Aishima Island) were undertaken during May 29-June 1, November 27--December 1, 1980.
1) Mishima Island lies in the Japan Sea about 46.3km off the northern coast of south-western Honshu and has an area of 7.86km2. There were obtained Urotrichus talpoides, Crocidura dsinezumi and Mus molossinus (Table 1) . Urotrichus talpoides of Mishima Island had larger body sizes than that of Honshu (Table 2), and there were found partial albinisms of several grades to occur quite commonly in Urotrichus talpoides specimens captured (Fig. 4) . Except for these three species, it was surposed that the wild land mammal inhabiting on Mishima Island was Mustela sibirica only.
2) Oshima Island lies in the Japan Sea about 7.5 km off the northern coast of southwestern Honshu and has an area of 3.1km2. There was obtained only one species, Apodemus speciosus. Tunnels of Mogera sp. were found commonly in the cultivated fields. It is said that Mustela sibirica is not found on this island.
3) Aishima Island lies in the Japan Sea about 14 km off the northern coast of southwestern Honshu and has an area of 2.6km2. There were obtained Mus molossinus and Crocidura dsinezumi. Except for these two species, it was surposed that the wild land mammal inhabiting on Aishima Island was Mustela sibirica only.
