Original Description
Radial proportion of the four spheres = 1: 3: 11: 13. Both medullary shells with small, regular, circular pores; inner cortical shell with regular, hexagonal pores; from the hexagon-corners arise small, radial by-spines, which at equal distances from the centre send out forked tangential branches, three from each spine, and by communication of these form the outer, delicate, cortical shell. Four main spines nearly as long as the shell diameter, three-sided prismatic, with four to six verticils of ramified lateral branches, each verticil composed of three forked branches, which ramify again.

Diameter of the four shells - (A) 0.26, (B) 0.22, (C) 0.06, (D) 0 02; length of the spines 0.24.
