Original Description

Radial proportion of the two shells = 3: 1. Cortical shell thick walled, smooth; pores regular, circular, three times as broad as the bars. Each pore on its outer opening with eight regular lobules, flower-like. Nine to ten pores on the half equator. Polar spines three-sided pyramidal, with three strong prominent edges, about as long as the axis, as broad as one pore. (Sometimes, as in the figured specimen, one spine is smaller than the other; this variety, otherwise identical, may be called Sphaerostylus calliope.)

Diameter of the outer shell 0.12, pores 0.015, bars 0.005; inner shell 0.04; length of the polar spine 0.08 to 0.12, breadth 0.02. [dimensions in mm]

Editors' Notes
Haeckel listed Stylosphaera calliope under the subgeneric name Stylosphaerantha, but did not include the subgeneric name in the species name.

Pl.16, fig.6 illustrates Sphaerostylus calliope, not Stylosphaera calliope.

Stratigraphic information for LM21 from Riedel, 1959, p.287.
