Original Description

"Test subglobular, early chambers spirally arranged, in the later development the last-formed chamber making up nearly half the surface of the test; chambers distinct, inflated; sutures distinct, somewhat depressed; wall fairly thick, generally reticulate; surface dull; aperture at the inner margin of the chamber with additional small openings at its periphery.

diameter 0.40-0.60 mm.

Extra details from original publication
This species is nearest related to Globigerina conglobata H.B. Brady, but is more spherical, the chambers being very different in their arrangement, and the surface much more smooth than in that species."
