Original Description
Test helicoid, dorsal side slightly-convex. ventral side very deep as a result of a rapid increase in height of the chambers; periphery moderately lobulate: edge evenly rounded ; whorls about three, the last with four chambers; sutures depressed, slightly curved; wall coarsely and conspicuously perforate; aperture a moderately high arch on the ventral side extending- from near umbilicus to near peripliery, with upper lip.
