Original Description

Test biserial, periphery broadly rounded; chambers distinct, much inflated, increasing very rapidly in the adult so that the last four chambers make up a very considerable amount of the entire test; sutures distinct, depressed; wall distinctly papillate throughout; aperture a low opening at the base of the last-formed chamber in the median line.

Size:
Length 0.45 mm; breadth 0.35 mm; thickness 0.25 mm.

Extra details from original publication
This species is a distinctive one in the great expansion of the last few chambers and the peculiar papillate surface. It brings the range of this genus well into the Eocene.
