Original Description
Test planispiral, biumbilicate, with strongly lobate to stellate outline. Chambers globular to suglobular in the earlier portion of the test; the ultimate chamber or, rarely, the ultimate and penultimate chambers are conical and radially elongate, 4.5 to 5.5 chambers in the final whorl, increasing slowly in size in the earlier part of the test and at a high rate with the development of the radially elongate ones. Sutures are straight, depressed and radial on both sides of the test. The primary aperture is a medium-high arch that is equatorial in position, symmetrically extending into the umbilicus and bordered by a lip. Relict apertures can be present in the umbilical areas. Scattered pustules are present on the earlier chambers of the test; the radially elongate chambers are commonly smooth. Test wall calcitic, hyaline, finely perforate; pore diameter is in the range of 1.0 to 1.8 microns.
