Original Description

Test biconvex, oval, the dorsal surface more convex than the ventral, which is umbilicate; periphery lobulated, peripheral margin rounded; chambers comparatively few, not more than five in the last-formed whorl, each much larger than its predecessor; sutures depressed, not limbate, gently recurved on both sides of the test; wall smooth and punctate, with a silvery lustre; aperture an elongate slit with a slight lip, opening at the base of the last-formed chamber into the umbilical depression.

Size:
Length up to 0.65 mm.

Extra details from original publication
This species belongs to the group of G. hirsuta (d'Orbigny) and is perhaps nearest to G. hirsuta, which typically has only four chambers to a whorl and with the sutures on the ventral side radial.

Editors' Notes
