内容記述（抄録等）
Radiolarian biostratigraphy of the Maizuru Group was examined in the Yanahara area, eastern part of the Okayama Prefecture, Southwest Japan. Six radiolarian assemblages (A-F) are discriminated within the radiolarians from the Maizuru Group. It is disclosed that the age of the Maizuru Group in this area incldues whole of the Middle Permian based on the radiolarian biostratigraphy, which indicates rather older age than previously supposed. Five species of Pseudoalbaillella including two new species are described in this paper.
