Figures 36.7, 36.8 View FIGURE 36

Description. Test small for the genus, planispiral and involute, both sides almost parallel, five chambers in final whorl; chambers inflated; sutures depressed and retral process appearing as small pores; umbilical area filled by shell material; periphery broadly rounded; aperture interiomarginal slit; surface smooth and moderately perforated.

Remarks. We could not find a named species to refer this to. It is characterized mainly by the small number of chambers in a whorl and the inflated, thick test.

Occurrence. Rare in the Yonahama and Minebari formations.
