The Carboniferous Hina Limestone is divided into three fusulinacean-endothyracean zones which are in ascending order Endothyra-Mediocris Zone, Eostaffella-Millerella Zone and Pseudostaffella-Profusulinella Zone and the primitive fusulinacea had already been reported and described in our preceding papers (Fujimoto and Sada, 1994a, b). This paper treats of the descriptions and the illustrations of the endothyracean species belonging to Planoendothyra, Granuliferelloides, Endostaffella, Endothyra, Zellerinella, Endothyranopsis and Eoendothyranopsis.
