In the spring of 1955 a lower jaw of both sides with third milk molar was excavated from a fissure deposit of Kawai limestone quarry at Yage, Iinoya-mura, Inasa-gun, Shizuoka Prefecture. Judging from the occurrence of Palaeoloxo don namadicus naumanni, having been described about thirty years ago from the Sahanma shell beds, it seems to be probable that this material must belong to the above subspecies, one of the most common subspecies in the Japanese Pleistocene. As the occurrence of milk teeth is the first example in Japan, they are described here. The geological age of the fissure deposit is considered to be the late Pleistocene (J2) and not to be the latest (J3).
