Original Description
"Test plano-convex, the dorsal side flat or even slightly concave, ventral side very much produced, periphery carinate, subacute, the series of which surround a depressed umbilical area; about seven chambers in the last-formed coil; sutures distinct, on the dorsal side curved, marked by a series of small, bead-like processes, the periphery of each with a slightly raised carina which marks also the line of coiling in the central portion, ventral side with the sutures nearly radiate, straight, much depressed, surface roughened with very minute, low spinose processes which rather uniformly cover the entire test; aperture elongate, narrow, on the ventral side of the last-formed chamber extending from near the periphery almost to the umbilical area."
