Original Description
The genus Archicircus is the most primitive and simplest form of all Stephoidea, and probably the commom amcestral from, not only of this suborder, but of the greater number of all Nassellaria (compare above p.893). The skeleton consists only of a quite simple sagittal ring, in which commonly a slight difference of both poles of the main axis (basal and apical pole) is visible, but no difference between the dorsal and the ventral bow of the ring. In my Prodromus (1881, p.447) the species of Archicircus were disposed partly in the subgenus Monostephus, partly in the genus Lithocircus.
