Original Description
Cephalis large, hemispherical, with irregular square pores and thin bars. Thorax flatly conical, three to four times as broad as the cephalis, beyond the collar stricture expanded nearly discoidally, with a delicate,network of small, subregular, hexagonal pores. (Similar in general form to Sethophormis aurelia, Pl. 55, fig 3, but without any trace of collar beams or radial ribs.)

Cephalis 0.04 long, 0.08 broad; thorax 0.04 long, 0.3 broad.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Although Haeckel treats this species as a radiolarian, Kofoid in 1912 suggests that this assignment is doubtful and that this species may be a tintinnid.
