Partial List of References
Conrad, T. A. 1831 Description of fifteen new species of Recent, and three
of fossil shells, chiefly from the coast of the United States Journal of
the Academy of Natural Sciences of Philadelphia 6 256-268, pl. 11. [Stated

Duh! someone thinks these species are synonymous. How about we ask David
Lindberg himself? In fact I might do so right now

regards
