The intertidal zonation of marine algae along the coasts of Toyama Bay, facing the Japan Sea, was studied. The field work was carried out in spring, 1958. Enteromorpha compressa-Scytosiphon lomentarius community is remarkable in the bay (Table 1). In this community there can be recognized two belts which are named after the dominant species. They are, from above downwards, Enteromorpha compressa belt and Scytosiphon lomentarius belt. The dominant alga of the former is Enteromorpha compressa and associated with this are the following forms : Cladophora utriculosa, Porphyra Okamurai and Bangia fuscopurpurea. The dominant alga of the latter is Scytosiphon lomentarius and associated with this are the following forms : Gymnogongrus flabelliformis, Gigartina intermedia, Enteromorpha linza, Corallina pilulifera, Chondria crassicaulis, Ulva pertusa, Grateloupia divaricata and Sargassum thunbergii. This community shows a distinctive characteristic of the inland sea. But in the eastern part of the day, it shows some characteristics of the open sea. And in the western part, the marine algae are discolored whitish. The return current of the sea and the inflow of rivers are most significant for those facts. The vertical width of the community is apparently much narrower. This is the special feature of the Japan Sea. An important point in reference to this phenomenon is the tidal factor.
