Original Description
Test plano-convex, dorsal side flat, ventral side strongly convex, slightly umbilicate, periphery subacute in the later portion, rounded in the earlier stages; chambers distinct, 4 making up the last-formed whorl in the adult, of uniform shape, increasing rgularly in size as added; sutures distinct, very slightly curved, nearly radial, slightly depressed; wall distinctly perforate with the early portion strongly papillate or with short spines, in the later chambers largely confined to the peripheral angle; aperture semicircular opening toward the umbilical end of the ventral side of the last-formed chamber. 

Size: Length 0.50 mm.; breadth 0.40 mm.; thickness 0.25 mm.

Extra details from original publication
This species rather strongly resembles one described by Schwager from the Middle Eocene of northern Africa, but is not as strongly convex as his species, and is apparently more coarsely spinose.
