Remarks. Bulimina truncana and B. alazanensis were originally described from the Eocene; while B. rostrata is a Recent species. These three species are similar in having a compact, conical, truncated general morphology, but they can be subdivided into two morphospecies based on the number of longitudinal costae on the test surface. We generally agree with Ujiié’s (1990, 1995) view of a wide range of variation in development of longitudinal costae; yet B. truncana Gümbel as illustrated by Ujiié (1990, pl. 12, fig. 8) shows numerous costae (about 10 are visible from one side), and this is considered to be out of the range of variation of B. truncana . Bulimina truncana has about five costae visible from one side.
Huang et al. (2007) reported abundant specimens of B. alazanensis from the Pliocene (mainly prior to 2.1 Ma) in the South China Sea, but did not illustrate any specimens. It might be the same species as B. truncana of the present study.
Occurrence. Common in the Yonahama Formation.
