Original Description

Shell composed of four concentric shells, two ellipsoidal cortical shells, and two spherical medullary shells. Proportion of their main axes = 10: 8: 3: 2.

Outer surface covered with numerous conical radial spines, about half as long as the main axis, half as broad at the base as the inner most shell.
