Original Description
Test medium, about as broad as high, ventral umbilical area widely opened, dorsally shows flattened spiral arrangement o! chambers which enlarges rapidly , the last three or four constituting the greater part of the test; chambers distinct, inflated, last one somewhat flattened on outer margin toward lower part; sutures distinct, deeply depressed; wall smooth, moderately perforate; aperture a large opening on ventral side, covered with a distinct, narrow, some times protruding lip.

Size: Diameter 0.50 mm .

Etymology: From Baroemoen a locality in Indonesia. [NB This was a Dutch spelling of the name so the pronunciation should be Baroomoon - editor's comment, J.R. Young 2019].

Extra details from original publication
This species ranges throughout the Telisa and Transitional Zone shales and is usually found in appreciable numbers. The species is related to Globigerina tripartita Koch, but differs by being more convex dorsally, having a slight apertural lip and by showing a higher spiral coil. It is also on the average somewhat smaller than Globigerina tripartita Koch.
