Diagnosis Test ovate in outline, trochospiral and commonly dextrally coiled, chambers enlarging rapidly in a somewhat flaring whorl, internal partition extends from the margin of the hooklike aperture in the apertural face and is enrolled to produce a small vestibule into which lead the two openings, one part of the partition crossing the chamber to attach to the wall on the spiral side and forming a smaller closed chamberlet adjacent to the spiral suture and over the previous basal aperture and part of the vertical one, hence opening only into the previous chamber cavity, internal partition partially resorbed as later chambers are added; wall calcareous, surface smooth; aperture an interiomarginal slit, and a second hooklike slit extending up the center of the apertural face from the base of the chamber on the umbilical side, the two diverging slits separated by a subtriangular flap directed toward the umbilicus, both opening into the area enclosed by the inner partition, septal foramen produced by resorption that enlarges the earlier openings. M. Eocene (Lutetian), Claibornian; Holocene; Antarctic; Pacific; North America. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
