Two freshwater mussel valves (one complete specimen). The exteriors are light brown to tan in color, with green color bands. The interiors are an iridescent, silver to white color with shallow muscle scars and small hinge teeth. The shells have silver interior nacre and a thin periostracum that is flaking near the umbos due to wear. The valves are elongated and covered with growth lines and striations. The valves are auriform in shape with rounded anterior and posterior edges.
