Original Description

"Test small, round in outline, with a broadly rounded, scalloped peripheral margin. Consists of 9-10 spherical, rapidly enlarging chambers, forming 2-2.5 whorls with 4 chambers in each whorl. Chambers of initial whorl very small, distinctly discernible on dorsal side of test only at magnifications of X 80-120, lie nearly on a level with the following whorl or slightly over it. Chambers of later whorl much larger, the last one is especially distinguished, with a diameter barely not exceeding that of the 2 previous chambers taken together. In the center of the ventral side is a broad depressed umbilicus. Spiral and septal sutures distinct, depressed, last ones on dorsal side nearly straight, short, on ventral side a little longer, slightly curved. Aperture slitlike, extends along margin suture from umbilicus to peripheral margin. Wall very thin, finely perforate, semitransparent, smooth, shiny."
