The intertidal zonation of the marine algae along the coast of Shimoda Bay, a small inlet on the Pacific shore of the Izu Peninsula, was studied. The field work which forms the basis of this paper was carried out in the spring of 1964. The results of the investigations have made it clear that the Hizikia fusiforme-Eisenia bicyclis association is distributed along the whole coast of Shimoda Bay. It consists of three belts, from above downwards, Myelophycus caespitosus, Hizikia fusiforme and of Eisenia bicyclis belts. It seems that the joint work of the shape of the small bay, the influential Black Current and the surfs from the open-sea have resulted in the production of the vegetation of marine algae. The association is a typical one of the open-sea communities along the coasts of the Pacific Ocean, and it is also a unique algal community of Japan, of the Far East. The Gigartina intermedia-Sargassum sagamianum association which is distributed in Sagami Bay and Suruga Bay is not found in this bay, and the Monostroma itidum-Scytosiphon lomentaria association which is one of the inland-sea communities was also not found in this bay.
