. Shell thin disc-shaped consisting of 4 shells: a double medullary shell with an eccentric microsphere, a large main cortical shell, and a peripheral equatorial ring. Microsphere very small, eccentric in the outer medullary shell. Outer medullary shell prunoid or subspherical, with large circular or polygonal pores and included in the cavity of the cortical shell with whom it is connected to the two faces of the latter by a bunch of oblique radial beams. These beams do not cross this shell. Cortical shell large, disc-shaped or lenticular and a little thicker than the diameter of the outer medullary shell. It has numerous very small circular to oval pores of various sizes and irregularly or, partly, radially disposed. This shell is surrounded by a peripheral ring with similar pores but usually smaller. Inside this ring there are radial costae that divide its circumference in unequal segments. Periphery of ring with tiny thorns.
