Population density, biomass and species composition of soil Collembola were investigated in the temperate forests mainly composed of Tsuga Sieboldii or Fagus crenata in Mt. Sobo, central Kyushu, Japan, in the late summers of 1961 and 1965. The Collembola community in Mt. Sobo was divided into the following three subcommunities by means of density and C_λ-index : Valley, Slope and Ridge subcommunities. The average density of Collembola on the ridges in Mt. Sobo was 48100 per m^2 and the average biomass of dry specimens was 145mg which was determined by the method described later. These figures for the density and biomass of the Collembola population were as large as those of Europe throughout. The regressions between the body length and the dry weight of the individuals in each taxonomic group of Collembola were obtained, and then the biomass of Collembola was estimated through the dry individual weights which were known from the regressions.
