Diagnosis Test globular, two hemispherical chambers visible externally, with slightly depressed suture; megalospheric test with large proloculus followed by narrow tubular flexostyle, axis of coiling oblique to that of the later biloculine chambers, microspheric test with flexostyle of more than one volution, followed by narrow evolute nummuloloculine chambers of one-half coil each, a large enveloping chamber with plane perpendicular to that of the earlier chambers, and finally by biloculine chambers that also may be in a different plane of coiling; wall calcareous, porcelaneous, that of early planispiral chambers thin, biloculine chambers with thicker wall, surface smooth; aperture areal, crescentic, nearly closed by a broad flat lip. Holocene; N. Atlantic, off France; Cuba; Virgin Islands; Puerto Rico. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
