Original description: All rings of the disk concentric, circular, or polygonal, with increasing breadth from the centre; the fifth ring twice as broad as the second. Pores irregular, roundish, three to four on the breadth of each ring; in the rings two to six times as large as in the equatorial girdle, which is half as broad or two-thirds as broad as the radius of the disk. Twelve bristle-shaped radial spines are connected by the girdle near to the points; four crossed spines arising from the central chamber; two others between these in each quadrant arising from the first ring.
Remarks on original description: Haeckel listed Stylochlamydium asteriscus under the subgeneric name Stylochlamys, but did not include the subgeneric name in the species name.[comment from RadWorld database]
