One of the edible green algae, Monostroma nitidum WITTROCK-Jap. name Hitoegusa, grows abundantly mixed with Porphyra tenera KJELLM., A ?? akusa laver, in the cultivating farms of the latter in Mikawa Bay. In Nov., 1934, the former was found mostly in the eastern, while the latter in the western part at Yosida laver-farm. Observation of surface salinity elucidated the facts that the growth of the former was most favourable where the direct influence of river water is slight, and that the latter was grown most where the salinity was intermediate, or where river and sea waters run side by side. Sandy bottom in the western part, as well as some other chemical nature of sea water, seems to have a certain relation to said distribution.
