Original Description
Cortical shell, as well as both medullary shells, very thin walled, with regular, hexagonal pores and thread-like bars between them. Pores of the outer shell twice as broad as those of the middle, and three times as broad as those of the inner shells. Radial proportion of the three spheres= 1: 3: 9; about twenty thin radial beams between them. At each nodal-point of the surface arises one bristle-shaped radial spine, half as long as the radius.

Diameter of the outer shell 220µm, middle 70µm, inner 25µm; meshes of the cortical shell 10µm; length of the spines 50µm.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Actinomma hexagonium under the subgeneric name Actinommantha, but did not include the subgeneric name in the species name.
