Original Description
"The specimens are very small for the genus [Globigerina]. The outline of the trochoid test is distinctly lobulate. The spiral side is pointed in the initial portion. The umbilicus is small and shallow. The final whorl, the dominant portion of the test, consists of 3 to 4 gradually in size increasing subglobular chambers. The sutures of the final whorl are strongly incised, those of the early test are not clearly visible. The extremely small, subcircular aperture opens into the shallow umbilical depression. The rough surface is covered by minute irregularly distributed spines. The thin walls are finely perforate. The direction of coiling is undetermined, 11 out of 19 specimens are coiling to the right hand side. The maximum diameter of the tests varies from 0.125 mm to 0.2 mm, average 0.15 mm. The height of the test is +/- 0.12 mm and the aperture has a diameter of +/-0.02 mm. Common in sample 38. "
