Diagnosis Test conical, apical proloculus followed by a few incomplete annular chambers that represent a reduced early spiral stage, and then by numerous low rectilinear chambers that enlarge rapidly in diameter as added, base of cone convex in the early stage, later flattened to concave; wall with thin marginal epidermis, overlying a series of narrowly spaced, short vertical exoskeletal beams that alternate in position with the marginal apertural openings, a shorter secondary beam occurs in front of each aperture, and a third order of shorter beams also may be present, beams intersected by at least two orders of horizontal rafters that parallel the septa, the series of beams and rafters producing a complex reticular subepidermal network; the endoskeletal pillars are circular in section near the underlying septum but semicircular in section toward the chamber roof; numerous apertures scattered over the base of the cone. M. Eocene; Caribbean: Leeward Islands: St. Barthelemy; Cuba; Bahamas; USA: Florida. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
