fyi, a friend in Europe who is a specialized collector in bivalves and
quite knowledgable sent me this comment off-list-seems like that
interior color is quite a wildcard in all this....

Dear Steve

The location and morphology matches
Chione mazyckii W. H. Dall, 1902 well, which
is widely distributed.

This is by no means only a small specimen
and my largest is 27.5 mm (Roatan). Some are inside
reddish, some rose and some white as is yours.
