Right valve, inner view. The low, rounded ridge that runs from near the beaks to near the middle of the ventral margin (on each valve) can be distinguished in this image. This ridge may not be present in all specimens, and perhaps not in all populations. Collected 03 Jul 2014. ID confirmed by Gerry Mackie.
