The success of the 1969 excavation at the Kamitakatsu Shell-midden Site and of the analysis of the material (at The University Museum, The University of Tokyo, from 1970 to 1972) could never have been achieved without a great deal of help from friends and colleagues, many with special knowledge and skills. Foremost among them I must thank Professor M. Horikoshi, Dr. Y. Hasegawa and Dr. Y. lwasaki for introducing me to the study of faunal remains as a major part of the food remains of early man, and for their skilled guidance and many profitable diseussions during the past three years. I also wish to gratefully acknowledge all those persons who gave special assistance to my study.
