Original Description
Test thick, higher than wide, shape subequal in a ll views, consisting of two whorls in a low trochospiral arrangement; chamber inflated, globular, loosely appressed, rapidly enlarging, about 10 in number, 3½ visible from the ventral side, last chamber large, equal to one half the test height; sutures distinct, strongly depressed; wall conspicuously cancellate, forming deep irregularly shaped depressions; primary aperture umbilical, a low elongate slit at the base of the last chamber, secondary sutural apertures prominent on the dorsal side.

Extra details from original publication
Sinistral and dextral coiling occurs with an apparent preference for the dextral type; otherwise there is little variation in the forms. This species resembles Globigerinoides subquadrata Bronnimann (1954 in Todd, et al.) Amer. Jour. Sci., vol. 252, No. 11, p. 680, pl. 1, figs. 5, 8a-c) but differs in the greater chamber inflation, size of the last chamber, visible initial spire, lower primary aperture, and more distinct sutural apertures. G. sacculiferous immatura LeRoy (Natuurk. Tijdschr. Nederl. Indie, Batavia, Java. dl. 99, afl. 6, p. 263, pl. 3, figs. 19-2 1) differs in the larger size, elongate early chambers, noncancellate test, and high arched primary aperture with a distinct lip.
