Two species and two subspecies of the Chlorophyceae, one of the Parsinophyceae and eight of the acritarchs belonging to eight form genera are described and illustrated : Tytthodiscus densiporosus n. sp. subsp. densiporosus n. subsp., T. densiporosus n. sp. subsp. minus n. subsp., Palambages sp., Pterospermella pterina n. sp., Leiosphaeridia cf. fastigatirugosa (STAPLIN) DOWNIE & SARJEANT, L. grandiformis n. sp., L. minuscula n. sp., Lancettopsis sp., Micrhystridium ariakense TAKAHASHI, Baltisphaeridium sphaeroides n. sp., B. nakajoense n. sp. and Cymatiosphaera pulchella n. sp. Morphological characteristics of the genera Tytthodiscus, Crassosphaera, Pleurozonaria, Tasmanites and Leiosphaeridia are discussed. According to PARKE et al. (1978), the fossil genus Pterospermella is a synonym of the recent genus Pterosperma, but the authors are inclined to accept the genus Pterospermella. These phytomicroplankton described in this paper are important for a basic knowledge of their stratigraphic and geographic distribution in the Neogene formations around the Sea of Japan., Transactions and proceedings of the Palaeontological Society of Japan.
