Sixteen valves comprising seven complete freshwater mussels with two odd valves. The exteriors of the shells range in color from light to dark brown and black. Subtle growth lines appear along the exteriors and the periostracum is flaking off, especially around their umbos. Shallow muscle scars are visible on the interior of the shells, which are iridescent with areas of light brown. The ellipse shaped shells have very small hinge teeth. The shells have rounded anterior edges and pointed posterior edges. The shells are covered with a brown dirt that gives them a rusty appearance.
