Test trochoid, compressed, composed of 2 to 2½ whorls, spire low, umbilicus large, open; chambers distinct, seven in the adult whorl, very little increasing in size as added in the adult; sutures distinct, depressed, radial; wall rough, probably due to the original spinosity of the surface; aperture opening into the umbilicus.
Extra details from original publication
This species differs from G. cretacea d'Orbigny in having seven instead of five chambers in the adult whorl and in the more open umbilicus. It somewhat resembles G. planispira Tappan from the Lower Cretaceous of Texas but is twice as large and the chambers are less spherical in shape and so the periphery is less lobulated. It occurs very abundantly.
The type material is probably Albian in age [comment from Chronos website]
