About 300 cellulolytic actinomycetes isolated from soils were tested for their cellulase activities estimated by means of filter paper swelling and carboxymethyl cellulose saccharifying activity. Then, 16 isolates which had shown relatively high levels of CMCase activity were selected and examined for their abilities of $\beta$-glucosidase production. Among them strain No. 109 was found to have highest level of intracellular $\beta$-glucosidase, and selected for the further studies. In this paper, the cultural, morphological and physiological properties, and cell wall composition of strain No. 109 were described in relation to the taxonomic status of this actinomycete. Based on the results obtained in these experiments strain No. 109 was identified to be a similar species to Streptomyces tanashiensis.
