Original Description
Cortical shell thick walled, with regular, circular, double-edged pores, twice as broad as the bars. Forty to fifty radial spines, three-sided pyramidal, half as long as the radius, with three elegantly denticulated edges. Radial proportion of the three spheres = 1: 2: 5. (Differs from Haliomma denticulatum. only in the double medullary shell and larger size.)

Diameter of the outer shell 140µm, middle 60µm, inner 30µm; cortical pores 10µm, bars 5µm; length of the spines 40µm, basal breadth 10µm.

Editors' Notes
Haeckel listed Actinomma denticulatum under the subgeneric name Actinommetta, but did not include the subgeneric name in the species name.
