The comparison of newly grown algal communities at the end of full one year after the denudation with the untreated Corallina community adjoined on the same rock surface was preciesely made by the samples at the lower littoral belt extracted from the previous data. Especially the repopulation of Corallinaceous algae, which have been considered generally as an impediment to the increase of useful algae, was carefully studied. The obtained results are summerised as follows : 1) The untreated surface is covered by a climax association of Corallina pilulifera, while the newly grown vegetation on the same level is a complex society. In the former case a few species of miniature erect perenial algae occupy all over the rock surface. In the latter, however, curstaceous and cushionous annual algae are comparatively dominant, erect-annual algae come next in frequency, and then erect-perenial algae (e.g. Corallina pilulifera, Sargassum Thunbergii) are sparesly scattered. 2) A species of Melobseiae (a crustaceous coralline) migrated as a pioneer to this denuded surface. But the present authors forecast that erect-perenial algae including Corallina will eliminate finally this Melobesiae-species and other annual algae from the surface.
