Original Description
Test large, coiled in a regular low-spired helix, 4 to 4½ chambers in the final whorl; ventral side with a small, deep umbilicus; periphery lobulate; chambers globular, increasing rapidly in length dorso-ventrally, but increasing slowly in the radial direction, so that the later chambers appear nearly of equal size; sutures depressed; wall hispid, rather coarsely perforate; ventral aperture a circular arch, opening partly into the umbilicus on the dorsal side at the intersection of the radial and spiral sutures. Common

Size: Diameter, 0.45 mm.; thickness, 0.31 mm.

Extra details from original publication
This form is similar to Globigerina dubia Egger (1857, Neues jahrb. Min. Geogn. Geol. Petref., p. 281), differing mainly in the accessory apertures on the dorsal side, and in the chambers of the dorsal spire increasing very rapidly in size at first, then more gradually in the later part,
