Remarks. Specimens from Miyakojima Island have five to six, occasionally seven, chambers in the final whorl, and peripheral keels are not robust; as such they are distinguishable from G. menardii

(Parker, Jones, and Brady). Coiling directions are mixed, but the dextral form predominates except for a single sample, MK02B. This trend in coiling direction is in accordance with those recorded for the Pliocene of other regions (see summary in Bolli and Saunders, 1985 ).

Occurrence. Common to abundant in all the formations of the present study.
