Diagnosis Test spherical, early rapidly enlarging globular chambers in a trochospiral coil, later with change in direction of coiling so that the final chamber covers the previous umbilicus but is not truly streptospiral, sutures depressed, peripheral outline lobulate; wall calcareous, perforate, pores within pore pits, surface with Globigerinacean spines that may be preserved in the early stage and not muricate; primary aperture lacking in the adult test, the final chamber having a few large arched supplementary apertures with distinct raised rim. M. Eocene (Lutetian) to U. Eocene (Bartonian); cosmopolitan. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
