Original Description

Cortical shell thin walled, with irregular, roundish pores, connected with both medullary shells by twenty stout radial beams, which are prolonged outside into twenty large three-sided prismatic spines. These are longer than the shell diameter, and have three dentate edges, being branched like a pine tree (with four to six ramified branches on each edge, decreasing in size towards the distal end); similar to those of Cladococcus abietinus (Pl. 27, fig. 3). Radial proportion of the three spheres = 1: 2: 8. Both medullary shells with regular, circular pores, twice as broas as the bars.

Diameter of the outer shell 0.2, middle 0.5, inner 0.25; length of the spines 0.25. [dimensions in mm]
