Specimens which cannot be assigned to established species
Low trochospiral, generally slightly lobate in outline, numerous chambers (7–11) in the last whorl, globular, sutures straight and depressed on both sides; wall finely perforate; wall surface rugose to smooth, with rugosities masking the inner whorl, then covering the first chambers of the last whorl, frequently organized in irregularly sized ridges that may cover the pores and run parallel to the spiral suture; surface of later-formed chambers may bear volcano-like perforation cones that progressively attenuate toward the ultimate chamber; shallow umbilical area moderate to large in size; umbilical area may be covered, at least partially, by large flaps from the ultimate and penultimate chambers that fuse along a slightly depressed line forming a cover-plate; primary aperture an interiomarginal arch, umbilical-extraumbilical extending toward the periphery; may have one to two small, weakly developed umbilical accessory (infralaminal) apertures in the last chambers.
