Diagnosis Test free or attached by one side during life, resulting in irregular growth, robust, coiling low trochospiral to nearly planispiral, one and a half to two rapidly enlarging whorls and about seven to nine laterally inflated chambers in the final whorl, chambers with umbilical flaplike projections on one or both sides, coiling variable, may be partially or wholly involute on one or both sides, or may be almost entirely evolute, sutures radial, straight to curved, depressed, periphery broadly rounded, peripheral outline circular, lobulate, or with one or more projections, depending on the mode of attachment if any; wall calcareous, optically granular, coarsely perforate, but with nonperforate apertural face, chamber flaps and area of attachment; aperture a broad and low interiomarginal and equatorial slit that may extend onto the imperforate side of the test and bordered above by a narrow lip, slitlike supplementary openings present beneath the umbilical flaps, but both flaps and supplementary apertures are reduced or disappear on the free side of asymmetrical attached specimens that have distinct imperforate and perforate sides. Miocene to Holocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
