"Description.- The test is calcareous, perforate; spinose on its surface. It consists of 2-2½ whorls of three closely embracing and slowly enlarging chambers in the last whorl. The dorsal side is flat, or gently convex, the ventral markedly convex. The chambers on the dorsal side are subquadrate; on the triangular, subconical. The equatorial profile is subcircular, the periphery slightly lobate; the axial periphery is subspherical or subangular in the last chamber. The intracameral sutures are deep; short, curved on the dorsal side; straight, radial on the ventral. The umbilicus is small, deep. The aperture is semi-arcuate; interiomarginal, umbilical-extraumbilical.
