Original description: Tympanida with two simple horizontal rings of different sizes, connected by four divergent columellae.

Description


Morphology: The genus Pseudocubus exhibits the characteristic form of an obelisk, or a truncated four-sided pyramid. The four edges of this obelisk, or the four "columellae," are the remaining parts of the two incomplete vertical rings; two opposite edges are the dorsal and ventral rod of the sagittal ring; the two alternate edges between these are the lateral rods of the frontal ring. The two horizontal rings, which become connected by the four divergent columellae, are the smaller mitral ring and the larger basal ring; both are either square or nearly circular.
