Original Description
Proportion of the longer axis to the shorter = 7: 6. Shell thick walled, with irregular, lobed meshes, four to six on the half equator, three to six times as broad as the bars; each mesh composed of three to six confluent roundish pores. Surface quite smooth, without thorns. The single polar spine pyramidal, as broad at the base as the largest mesh, half as long as the radius.(This species is closely allied to the foregoing, but differs in the smooth surface and the larger meshes.)

Major axis 0.15, minor axis 0.13; pores 0.01 to 0.03, bars 0.003 to 0.01; length of the single spine 0.04, basal thickness 0.03.

Editors' Notes
Description: The "foregoing" species to which Haeckel refers here is Lithapium halicapsa Haeckel, 1887a.
