Diagnosis Test planispiral and partially evolute, about eight to ten gradually enlarging chambers in the final whorl, sutures radial, gently curved, deeply incised toward the umbilici but without intercameral lacunae, both umbilici filled by a complex of fused imperforate and tuberculate umbilical flaps, one from each chamber, the tubercules thickened by lamellar additions until older ones become pillarlike, intercommunicating umbilical cavities remain in the spaces between the platelike flaps and supporting pillars, no rotalid septal flap, no septal or spiral canals, retral processes, fossettes, or sutural pores, periphery rounded, peripheral outline lobulate; wall calcareous, perforate, optically radial but morphologically microgranular, surface with prominent tubercles on lower part of apertural face and on the preceding whorl adjacent to the aperture, as well as over the umbilical structure of flaps, tubercles, and pillars and extending along the margins of the incised sutures; primary aperture a low, narrow, interiomarginal and equatorial arch. L. Paleocene (Danian) to Oligocene; England; France; Libya; USSR. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
