Diagnosis Megalospheric tests conical to cylindrical, up to 1.5 mm in height and up to 1.1 mm in diameter, early stage with globular protoconch and hemispherical deuteroconch, and by a large excentric trochospire of some thirty chambers, with axis of coiling up to 90¡ from that of the later cylindrical part of twenty to twentyfive discoidal rectilinear chambers, trochospiral part compressed and elliptical in vertical section, with sharply angular carina, until the beginning of the rectilinear part, the later half of the trochospiral chambers subdivided by two orders of vertical beams in the relatively wide marginal zone, the beams of successive chambers commonly aligned but lacks any horizontal rafters, pillars present in the central zone, those of successive chambers alternating in position, central zone filled by secondary deposits, base of the test flat to slightly inflated; microspheric test lower conical, up to 2.1 mm in height and 3.0 mm in breadth of the base, early microspheric stage unknown, probably trochospiral; wall finely agglutinated in the microgranular calcareous base; apertural openings subvertical at the base of pillars in the central zone, the openings at the margin of the radial zone being most evident in section. U. Albian to L. Cenomanian; Spain, France. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]

Diagnosis Test conical, megalospheric embryo with spherical eccentric proloculus and hemispherical deuteroconch located below the apex, followed by short series of almost planispiral chambers and then by more numerous rectilinear chambers, microspheric generation with numerous spiraling chambers prior to becoming rectilinear; wall with thin marginal epidermis covering the long widely spaced primary exoskeletal beams, two orders of intercalated shorter beams, and two orders of horizontal partitions or rafters in each chamber resulting in a complex reticular subepidermal network; numerous endoskeletal pillars may partially encircle the apertural pores; aperture a series of pores over the base of the cone. L. Cretaceous (Aptian) to Oligocene; cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
