In spite of the fact that the tertiary fossil flora of Japan is fairy well known, that of Pleistocene is rather little studied. Last year I had an opportunity to collect some fossil flora of Older Pleistocene in the suburb of Kyoto, Prov. Yamashiro. There have been found 23 different species satisfactory identified. Some of them are quite extinct or only their allied species are found in remote districts, while the. other are still living.
From these facts, as well as from the habitats of the flora it might also be possible to consider the climatic and topographical changes that have taken place during the course of the era in the region under consideration, the geological age of which is identical with that of Naganuma bed in South Kwanto.
I wish to express here many sinsere thanks to Prof. K. KORIBA, under whose direction this study was undertaken. Further I am deeply indebted to Prof. S. NAKAMURA and Prof. J. MAKIYAMA for their most valuable suggestions upon geological questions and also to Prof. Y. OKADA who kindly determined for me the remains of marine animals. I wish to thank Prof. Y. YAMAMOTO, of Taihoku Imp. University, Mr. Y. YOSHINAGA of Kochi Prefecture and Mr. Y. TANAKA of Fukuoka imp. University, who have so kindly sent materials for the writer's use.
