    This is a very rare find at this site. Although two members of the genus have been reported along the C and D Canal, this is the only one I've found at Reedy Point in 17 years of collecting there!


    PLEASE NOTE:  It is possible that this was carried there during frequent human activity - perhaps in a tire tread from a vehicle that came from another site along the canal.


    This specimen has a 4mm pearl bud near the hinge on the interior side of the valve.


    Because there are more than one species of Pteria at the canal and this shell is heavily worn, I am refraining from narrowing it down to a species. Of the two reported, only one really resembles it. P. petrosa (Conrad) has strong, concentric growth rings, but no costae. P. laripes (Morton) has strong costae and fine growth lines, so is probably a match.
