Original Description
Cephalis very large, flat, cap-shaped, with hexagonal base, trilobed, of similar form and structure to the two preceding species. The flat, discoidal thorax has also the same form, with nine stout ribs and five concentric, nine-angled rings; its forty-five large meshes,however, are not so simple as these (Pl. 57, fig. 9), but are subdivided into irregular, smaller meshes by interpolated radial beams connecting the concentric rings.

Size: Cephalis 100µm diameter, thorax 300µm diameter.

Editors' Notes
Haeckel listed Sethophormis enneastrum under the subgeneric name Enneaphormis , but did not include the subgeneric name in the species name.
The \two preceding species\" refers to Sethophormis rotula (pl.57, fig.9) and S. triloba in Haeckel, 1887a.]"[comment from RadWorld database]
