Original Description
Cortical shell as well as both medullary shells thick walled, with regular, circular pores, of the same breadth as the bars. Radial proportion of the three spheres= 1: 3: 8; radial beams between them very numerous (thirty to fifty or more ?). Entire surface covered with short thick conical spines, only one-fifth as long as the radius.

Diameter of the outer shell 160µm, middle 60µm, inner 20µm; cortical pores and bars 7µm; length of the spines 15µm.

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

Haeckel here considers the specimen described by Stöhr in 1880 as Actinomma entactinia (Ehrenberg) to be a separate new species, differing from the specimen Haliomma entactinia described by Ehrenberg in 1873 and 1875, which on p.74 Haeckel reassigns to Carposphaera. According to ICZN (1964) art. 49, Actinomma entactinia Haeckel, 1887 is an invalid name.
