Original Description

Test medium in size with broadly rounded periphery, lobulate, chambers often irregularly placed; chambers rounded or club- shaped, inflated, up to 14 or 15 in number, 4 to 5 in the last-formed whorl; sutures depressed; wall thin, spinose or almost smooth with only the rounded spine bases protruding; aperture often irregularly shaped, narrow to semicircular, marginal or interiomarginal, with a lip of varying width.

Largest diameter about 0.6 mm.

Extra details from original publication
Remarks: This species is close to G. digitata, only differing in not having the long, pointed digitate chambers. Many of the specimens seen in an assemblage of G. digitata are identical, especially juvenile forms. This new species is never common in any one sample. It occurs first in samples from Zone N.17 but, since little material from Zone N.16 was seen, the position of its first appearance is uncertain. It was replaced by G. digitata either at the base of the Pleistocene or somewhat higher.
