Original Description
Radial spines thirty-two, disposed in a similar manner to those of the former species (eight primary and twenty-four secondary); also the spongy shell of the same shape. The difference arises in the form of the spines, the three edges of which are much broader and spirally contorted around the axis; and thus the corresponding branches of the verticil do not lie in the same meridian-plane, but alternate one with another.

Diameter of the spongy shell 0.4, of its cavity 0.1, of the central cube 0.02; length of the spines 0.8 to 1.2, breadth 0.04.

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

Description: "...the former species" to which Haeckel refers here is Octodendron verticillatum Haeckel, 1887a.
