Original Description
This genus comprises the members of the lineage extending from Psychospyris parva through P. intermedia to P. grandis. There is a strong tendency for shell development to be concentrated in the frontal plane, and for the shells therefore to be discoidal in general form. The outer part of this disc usually con-sists of two lattice-plates joined by bars which give the appearance of a radially chambered structure, and the inner part (corresponding to the cephalic cavity or more) hollow. The primary and secondary lateral bars are well developed, and there is no basal ring in P parva, though it may be present in the other species. Below the collar pores, and marked off from the re-mainder of the disc by the primary lateral bars and obliquely downwardly directed bars arising from them, a type of ""pocket"". There are commonly two prominent bars arising from the top of the D-shaped sagittal ring (in the position denoted as ""q"" by Petrushevskaya, 1969), and extending obliquely up-ward to the spongy zone at the top of the skeleton.

Etymology: From the Greek psyche (=buttery) and spyris (=basket), and is feminine"
