. Shell large, disc-shaped with a small double medullary shell and a wide cortical shell. Microsphere very small, eccentric in the outer medullary shell and connected to it through a few cylindrical beams of different length. Outer medullary shell spherical or slightly prunoid with wide circular or polygonal pores separated by thin intervening bars and included in the cavity of the cortical shell to which it is connected with the two faces of this shell by a bunch of very short rays. Cortical shell flat, very thin and perforated by numerous very small polygonal pores arranged either disorderly or, partly, radially. Periphery of disc armed with numerous threebladed, short, and pyramidal spines disposed in several planes.
