Kennett & Srinivasan (1983):
Test low trochospiral, equatorial periphery strongly lobulate; axial periphery rounded, chambers subglobular initially, ovate, to rapidly elongate in later stages; four to five rapidly enlarging chambers in the final whorl;
sutures distinct, radial, depressed; surface densely perforate, finely hispid; aperture umbilical, becoming umbilical-extraumbilical, a rather low arch with a narrow lip. |
