Dorsal view of hinge margin. wider in much the same way as when the adductors are severed in other lamellibranchs. Fig. 9 represents the various ruptures, and at the same time illustrates different attitudes of the foot. In the adult the pedal opening extends back nearly half way to the center of the body. In the young it extends a little over a third back. Viewing the shell from above, the exposed ligament presents some curious features which I have tried to represent in Fig. 10. In the vicinity of the umbones a narrow elongated wedge-shaped substance, black in color, is seen, behind which a brown oval ligament appears, split at its posterior end in which is wedged a white substance. From the junction of the two valves anteriorly a narrow wedge-shaped substance narrowing posteriorly is peculiar in being a polished white. In the young.
