Original Description
Test: very low trochospiral, compressed, spiral side moderately convex, umbilical side slightly concave. Equatorial periphery, elongate. Axial periphery rounded to sub-acute.
Wall: calcareous, perforate, smooth.
Chambers: rather strongly compressed; about 15 arranged in 2½ whorl. The 6 chambers of the last whorl increase rapidly in size.
Sutures: spiral side: radial, depressed. Umbilical side: radial, depressed.
Umbilicus: narrow, deep open.
Aperture: low arch, interiomarginal, extraumbilical-umbilical with a distinct, rather wide lip. The apertures of the previous chambers remain open into the umbilicus.
Coiling: random.

Size: Largest diameter 0.20 to 0.40 mm.

Extra details from original publication
Remarks: This species closely resembles Globorotalia elongata Glaessner. It is distinguished from this species by the more rounded axial periphery, the convex spiral side with radial sutures, the deep narrow umbilicus, and the distinct, rather wide apertural lip.

Occurrence: The species is present in the Redbank at Atlantic Highlands and New Egypt and in the Redbank in the Clementon Whitesville, and Glendola wells.
