Original Description Test helicoid, dorsal side flattened or slightly convex, ventral side very deep as a result of the rapid increase in height of the chambers; periphery moderately lobulate; edge rather abruptly rounded, with shoulder; whorls 2½ to 3, the last with about 4½ chambers; sutures depressed, on the dorsal side curved and oblique, ventrally nearly radial; wall coarsely perforate, consuspicously spinose, rather reduced on the last chamber; aperture a moderately low arch opening into the umbilicus, with an upper lip. Rare Size: Length, 0.42 mm.; breadth, 0.34 mm.; thickness, 0.29 mm. Extra details from original publication G. topilensis Cushman (1925, Contr. Cushman Lab Foram. Res., vol. 1, pt. 1) is very much more lobulate in the adult form than this rather regular species.
