An incorrect version of Figure 16 was presented in Satoshi and Takami. 2015. Illustrated guide to Pliocene foraminifera from Miyakojima, Ryukyu Island Arc, with comments on biostratigraphy. Palaeontologia Electronica 18.1.3A: 1-140. palaeo-electronica.org/content/2015/1016-foraminifera-of-miyakojima. The following is the correct figure.

1985 Globorotalia crassaformis oceanica Cushman and Bermudez — Bolli and Saunders, p. 233, fig. 37.11.

1985 Globorotalia (Turborotalia) crassaformis oceanica Cushman and Bermudez — Ibaraki, p. 124, pl. 7, figs. 3, 4.

Remarks. Differentiation of this species from Globorotalia crassaformis is difficult in young specimens that do not show such features as an open umbilicus and a wide aperture.

Occurrence. Three specimens from a single sample of the Minebari Formation.
