Original Description
Test small, rotaliform, closely coiled, somewhat compressed, equally bioconvex; peripheral margin bluntly angular, lobate; chambers increasing gradually, 5 in last-formed whorl, moderately inflated, overlapping on dorsal face; sutures distinctly depressed and strongly curved on the dorsal side; shell wall thin, smooth, finely punctate; aperture a single moderately arched slit protected by a definite flaring flap at base of septal face and extending into the small but distinct umbilical depression.

Size: Diameter up to .4 mm.; average .3 mm."

Extra details from original publication
In general the structure of the test resembles G. pseudobulloides, but its shell surface is finer and smoother, the chambers are distinctly compressed rendering the periphery obtusely angular, the sutures curve markedly on the dorsal face, and the size of the test is smaller.
In the upper Midway G. compressa is common in the siltless clays that carry a fauna rich in hyaline species. No similar species occurs in Cretaceous formations. One in the Claiborne referred to G. aequilateralis bears a resemblance in the shape of its chambers but differs in its manner of coiling.

changed that - and this means all species from the publication are now cited the same way.
