Original Description
"Test small for the genus, composed for the most part of 3 last-formed chambers, the last one comprising about half the test, earlier chambers visible in a small, low spire; chambers globular, increasing very rapidly in size as added; sutures deeply depressed; wall thin, finely cancellated; aperture single, ventral a high, arched, slightly rimmed opening projecting into the last chamber. Length 0.35-0.42 mm.; thickness 0.25-0.30 mm. This species differs from Globigerina bulloides d'Obigny in having 3 chambers comprising the last whorl, in its cancellated instead of spinose wall, and its high arched aperture which may be even elongated in some specimens."
