Original Description
Test free, trochospiral, subglobular to relatively high-spired, periphery broadly rounded, peripheral outline lobulate, umbilicus open; commonly with four subglobular chambers in the final whorl, and may have smaller thin-walled final chamber somewhat resembling a bulla, but with a normal aperture; sutures distinct, depressed, slightly curved; wall calcareous, perforate, surface finely hispid, most prominently in the umbilical region; aperture umbilical, with a narrow lip, a fairly high open arch.

Size: Diameter, 0.28 mm.; thickness, 0.23 mm.

Extra details from original publication
Remarks: G. aquiensis, new species, is similar to G. spiralis Bolli in being high spired, but differs in being considerably smaller, with fewer and more globular chambers per whorl, and in being finely hispid.
