A scheme of the zoning which is best applicable to the Upper Cretaceous in Japan and adjacent areas is tabulated, with zonal indices and ranges of principal associated species. The indices are species of Inocerami and ammonites of the superfamily Desmocerataceae. They are mostly particular to the Japanese province, so that the scheme is entirely different from the well known ones in Western Countries. World-wide correlation is, however, attempted as far as possible from the careful considerations of genera and species-groups that are common to Japanese and extra-Japanese provinces. A tentative result of the approximate correlation is presented, but several questions remain, especially about the exact position of the boundaries between stages. The Japanese sequence will throw much new light on the Upper Cretaceous sequence in the vast Indo-Pacific area.
