Isaac Lea described this species in 1834. The shell is elongate with a well-rounded anterior end and a slightly narrower and blunter posterior end. The periostracum is golden brown to yellowish-green with green rays over most of the surface. The ventral margin of the shell is relatively straight in young animals but tends to become concave with age. The posterior slope has a corrugated appearance. There are two chunky pseudocardinal teeth in the left valve and one in the right. Two slightly curved lateral teeth are found in the left valve and one in the right. Nacre color is variable, ranging from bluish to dirty white. (Parmalee and Bogan 1998).
