Original Description
Cortical shell thick walled, with regular, circular, hexagonally framed pores, three times as broad as the bars. Pores of both medullary shells regular, circular. Radial proportion of the three spheres = 1: 2: 4; about forty thin radial beams between them. At each nodal-point of the surface arises one short, three-sided pyramidal, radial spine, about one-third as long as the radius.
Size: Diameter of the outer shell 160µm, middle 80µm, inner 40µm; cortical pores 12µm, bars 4µm; length of the spines 30µm, basal breadth 15µm.
Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Actinomma facetum under the subgeneric name Actinommantha, but did not include the subgeneric name in the species name.[comment from RadWorld database]
