Original Description
Test of medium size, low trochospire; peripheral margin elliptical, strongly lobate; generally five chambers in the last whorl, increasing gradually in size as added; chambers petalloid to crescent-shaped on both spiral and umbilical sides; ovoid in apertural view; sutures straight, depressed; primary aperture extraumbilical-spiroumbilical in position; umbilicus small, circular.

Etymology: This species derives its name from its stratigraphic range, the Albian, since it seems to be restricted to the Albian.
