Original Description

Radial proportion of the two shells = 2:1. Cortical shell thin walled, thorny, with irregular, roundish pores, two to four times as broad as the bars; eight to twelve on the half equator. Polar spines conical, one to one and a half times as long as the axis of the outer sphere, one-fourth to one sixth as thick at the base. (Resembles Sphœrostylus ophidium, P1. 16, fig. 14, but differs in the straight regular conical polar spines, both of equal length and similar form.)

Size:
Diameter of the outer shell 0.12, pores 0.01 to 0.02, bars 0.005; inner shell 0.06; polar spines 0.1 to 0.16 long, 0.03 broad.
