Androcyclas
Taxonomy
Androcyclas was named by Jørgensen (1905) [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.]. It was considered monophyletic by Jørgensen (1905).
It was assigned to Pterocorythidae by Jørgensen (1905).
