J. B. Knight 1930Hemizygae with strong transverse costae that are confined to the
sides of the volution, and with fine revolving lirae on the sides and base. The columellar section shows a slightly arcuate columella, a sub-circular opening and a relatively thin outer wall with no localized thickening (Fig. 3, F). The pseudozygopleuroid nucleus has been observed in numerous specimens.
