Diagnosis Test tiny, gradually enlarging, spherical chambers in a low trochospiral coil, about four and a half to five in the final whorl, the last somewhat displaced toward the umbilical side, sutures radial, gently curved, depressed, periphery rounded, peripheral outline lobulate; wall calcareous, thin, finely perforate with widely spaced pores, surface smooth in the proximal part of the chambers, and spines concentrated near the periphery, the more delicate simple spines of rounded section interspersed between larger spines of triangular section; aperture interiomarginal, a low umbilical-extraumbilical arch with a narrow but distinctly recurved bordering lip. Pleistocene to Holocene; Caribbean; N. Atlantic: Denmark Strait; Antarctic and Subantarctic S. Atlantic. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
