The annual succession extending from 1950 to 1958 of Desmids communities in Tatara-numa, a small lake, has been studied with attention to the organic pollution. As shown in Fig. 1,Tables 1 and 2,the Desmids communities have succeeded during these years as follows : Desmidium-Micra-sterias period→Cosmarium period→Staurastrum-Cosmarium period→Cosmarium period. When the lake was subjected to the highest degree of pollution in 1955-1956,the Desmids communities almost disappeared, especially the species of the genus Micrasterias and also those of large types of other genera entirely vanished. On the other hand the species of Scenedesmus, and those of smaller types of Cosmarium and Staurastrum occurred remarkably.
