Description
Color: White

In the shell a strongly developed keel is running down the middle of the shell from the umbo to the lower margin, which is distinctly angular at the point of termination of the keel, and not evenly rounded. The shell is considerably deep, the valves being strongly inflated, higher than long, and somewhat heart shaped in outline. The umbo is strongly curved inwards and the lunule is deeply excavated. The hinge teeth are strong and there are deep pits developed beneath the lateral teeth. The shell is strongly radially ribbed. Thee ribs are broad and well rounded, and number about 22. The anterior part is broader and the ribs in this part are broader and more widely spaced than the posterior part. The posterior part is narrower and the ribs in this part are comparatively narrow and more close-set. The interstices between the ribs are transversely grooved.
