Diagnosis Test planoconvex to concavoconvex, with a low trochospiral coil, globular proloculus followed by two to three whorls, ten to thirteen chambers in the final whorl, spiral side evolute, concave where the chamber surface is excavated below the level of the elevated sutures, umbilical side involute, sutures thickened, nearly straight and radial, slightly elevated on the spiral side, strongly elevated on the umbilical side and terminating in a prominent raised boss at the umbilical margin, umbilical bosses of earlier chambers and whorls forming a pillarlike umbilical mass, periphery subangular in early whorls, broadly rounded in the final chambers; wall calcareous, coarsely perforate except for the imperf orate apertural face, apertural lip, and limbate sutures, perforations may be obscured by secondary deposits on the spiral side but remain open between the imperforate elevated sutures on the umbilical side; aperture a low interiomarginal and equatorial arch, bordered by a prominent narrow lip, and continuing beneath the basal margin of the chamber onto the umbilical side.
