• The intertidal zonation of marine algae along the coasts of the Satsuma Peninsula, facing the East China Sea, was studied. The field works were carried twice in March, 1958 and 1959. As the results of the investigations, two communities have been found. 1) Gloiopeltis furcata-Myelophycus caespitosus-Hizikia fusiforme-Eisenia bicyclis community is found at Akune, Ushinohama and Kushikino. As described in the previous works, this shows a distinct characteristic of the open sea type community of the middle Pacific Ocean, and is distributed from Onahama, Boso Pen., Izu Pen., Ise Bay, Shima-Matoya Bay to the Hyuganada and Chikuzen in Kyusyu. 2) Gelidium divaricetum-G. pusillum-Corallina pilulifera community is found at Noma, Bonotsu, Makurazaki and Hanasezaki. In this community there can be recognized three belts. From above downward they are the Gelidium divaricatum belt, G. pusillum belt and Corallina pilulifera belt. The dominant alga of the first belt is Gelidium divaricatum associated with Gloiopeltis furcata, Porphyra crispata, Monostroma nitidum, Herposiphonia tenella, Gloiopeltis tenax, Nemalion pulvinatum and Bostrychia binderi. The dominant alga of the second is Gelidium pusillum and the associated forms are Myelophycus caespitosus, Carpopeltis flabellata, Boodlea coacta, Petrospongium rugosum, Colpomenia sinuosa and Ulva conglobata. The dominant alga of the third is Corallina pilulifera, associated with Enteromorpha sp., Gigartina intermedia, Mastophora rosea, Hydroclathrus clathratus and Caulerpa sp. All these algae have minute bodies and form a close cover over or carpet the rock. Consequently the algal vegetation is poor. Bostrychia binderioccurs in a group and Chlorophyceae are more abundant in this community. Compared with the former community, these characteristics are very prominent in the latter though rather small in number, and may be assumed to be subtropical or the tropical, common to the algal vegetation in South-West Is., Micronesia, India, Gold Coast (Africa) and Florida(North America). The boundary line between the two communities is between Kushikino and Noma.
