Original Description
Cortical shell as well as both medullary shells thick walled, with regular, circular pores, twice as broad as the bars; between them at each nodal-point one bristle-shaped radial spine, one-third as long as the radius, with conical base. Radial proportion of the three spheres=2: 3: 8; only six radial beams between them (opposed in pairs in the three dimensive axes).

Diameter of the outer shell 150µm, middle 60µm, inner 40µm; cortical pores 8µm, bars 4µm; length of the spines 25µm.

Editors' Notes
