Original Description (from Dall, 1898, p. 740):

“Oligocene of the Chipola horizon, in the lower bed at Alum Bluff, Chattahoochee River, Florida; Ball.

Shell small, thin, with compressed, flattish umbones and fourteen or fifteen feeble, obsolete ribs on the lower part of the disk separated by equal shallow interspaces; the whole surface marked with fine concentric lines; ears subequal, concentrically striate, not radiated, except the byssal ear, which has five scabrous riblets and a well-marked notch; interior fluted to correspond with the external ribs; the cardinal crura developed. Alt. reaching 15-18 mm. in fully adult shells; figured specimen 8, lat. 7.5 mm.

This small shell is sufficiently distinct in its characters to indicate its specific rank, though it may be that it attains a larger size when adult than any of the specimens obtained. One or two of the specimens have the ribs more rounded and prominent than the majority.”
