Original Description

There are usually about four chambers in the last-formed coil. The ventral side is coarsely papillate, especially about the aperture which is narrow and elongate, between the periphery and umbilicus

Extra details from original publication

This is not the same as the Upper Cretaceous species of d'Orbigny.
It is a common species in the Pacific as well as in the Pliocene of some parts of California.

Editors' Notes
The descriton here is brief since it was made in order to  provide a new name, since G. crassa Brady was a junor homonym of G. crassa d'Orbigny. [editor&apos;s comment - JRY 2019]
