Original Description

Test much compressed, the dorsal side with all the chambers visible, ventral side only those of the last-formed coil, sides nearly parallel, periphery broadly rounded; chambers distinct, three or four making up the last-formed coil, early chambers subglobular, later ones becoming more compressed, and the inner margin fairly straight; wall finely and evenly reticulate; aperture on the ventral side, elongate. 

Diameter 0.45 mm.; thickness 0.25 mm.

Extra details from original publication
This is a peculiar species in its very much compressed form, the nearly straight inner margin of the chambers, and the much finer reticulate surface than usually occurs in this genus.
