Original Description
Test about equally plano-convex, compressed, periphery with prominent, slightly flattened spines, and slightly keeled; chambers 6 or 7 in the adult whorl, increasing rather evenly in size as added, inflated, the periphery of each in the adult usually ending in a somewhat tangentially pointing spine; sutures distinct, particularly on the dorsal side, slightly curved, ventrally nearly radial, strongly depressed; wall smooth, rather coarsely perforate, especially on the ventral side; aperture a low opening near the umbilical end of the ventral margin of the last-formed chamber. 

Size: Length with spines 0.40-0.60 mm.; without spines 0.28-0.35 mm.; breadth with spines 0.36-0.46 mm., without spines 0.24-0.30 mm., thickness 0.10-0.12 mm.

Extra details from original publication
This species differs from G. lehneri Cushman and Jarvis in the smoother surface, less inflated chambers, and the periphery with a single large spine on each chamber instead of several small spines.
