Diagnosis Test large and robust, chambers in low trochospiral coil of two and a half to three and a half whorls, six to seven chambers in the final whorl, spiral side evolute, umbilical side involute with slightly depressed central area, an umbilical lumen covered by overlapping umbilical extensions of the chamber walls that do not form a plug, the umbilical lumen connecting with the simple sutural canal system that extends onto the spiral side to join the canal system just above the spiral sutures, sutural canals open to the exterior through paired fossettes, retral processes present but not reflected at the exterior of the test, sutures curved, oblique on the spiral side, nearly radial on the umbilical side, periphery broadly rounded; wall calcareous, perforate, surface covered by pustules that are most prominent on the umbilical side; aperture multiple but the one or two rows of tiny openings along the base of the apertural face may be obscured by the heavy pustule development, septal foramina of earlier chambers enlarged by resorption to an interiomarginal slit that extends from the periphery onto the umbilical side. Pleistocene; Antarctica. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
