Original Description
The four primary spines and the ventral sagittal one are present. The apical spine, D, runs close to the cephalic wall, and finally protrudes as a marginal topsword, thick and large, and furnished with three broad edges. There is, consequently, no distinct columella. The three basal spines, A, Lr and Ll protrude from the upper part of the thorax (the spine A lowest down) like fine needles, which pierce the wall, no part of them being enclosed in it as ""thoracic ribs"". The ventral, sagittal spine also protrudes like a similar needle in the region of the neck. There is also a long, inner axial spine, which reaches as far down as to the upper part of the abdomen.

Editors' Notes
I referred the following species [Androcyclas gamphonycha (Jørgensen) in Jørgensen, 1905] previously to the genus Pterocorys Haeckel, but I now find it necessary to separate it from this genus which has strong side swords on the thorax. On the other hand, there is probably no doubt that the genus Theoconus Haeckel to some extent corresponds to my genus Androcyclas. Thus, Theocorys jovis Haeckel (1887a, pl. 69, fig. 4) is undoubtedly of quite the same structure as Androcyclas gamphonycha, the byspines on the abdomen of the latter only excepted. As, however, Haeckel’s group Theocyrtida, to which Theoconus Haeckel and Theocamptra Haeckel belong, is defined as Tricyrtida without radial apophyses, I have thought it most practical, to avoid confusion, temporarily to erect the new genus Androcyclas.
