Thirteen complete freshwater bivalves. Four of the bivalves are sealed closed with nine bivalves matching but not attached are present (18 valves). The shells are auriform in shape with colors ranging from dark tan, black, gray to white in combinations. The umbos are typically white, but coloration patterns vary with some showing swirls, color bands, and flaking. Growth lines are present and occasionally raised. The interiors of the shells are dull iridescent white nacre (mother of pearl) and have visible muscle scars.
