Remarks. Species of Globobulimina from Miyakojima Island converge with single species. Papp and Schmid (1985) discussed the taxonomy of Bulimina pupoides and Bulimina ovata , and concluded that they were junior synonyms of B. pyrula . All three species are known in Japan and have been distinguished as such. Thus, we cannot easily conclude that all of them are synonyms, because the discussion by Papp and Schmid (1985) is based solely upon general test shape. The inner structure, such as the tooth plate that has been emphasized in former studies, was not mentioned.

Occurrence. Rare in the Minebari and Yonahama formations.
