Description

Five freshwater mussels, two complete and one partial speicmens. The exteriors of the shells are brown to light brown in color. The interiors of the shells are slightly iridescent, silver to white color. The shells have a small amount of silver interior nacre and a thin periostracum. The periostracum on the umbos of the shells is flaking off due to wear. The ellipse shaped shells are elongated and are covered with growth lines and striations. The valves have moderately sized muscle scars, small hinge teeth, rounded anterior edges and pointed posterior edges.
