Dear Conch-Lers -

I did not expect any rave notices about my recent contribution regarding
various cymatium species (nor did it deserve any),  but I was hoping at
least one person (hopefully more)  would  give me his thoughts as to what
constitutes a valid species as compared to a geographical subspecies.  Is
it simply a matter of degree?  Or merely at the whim of the describer?  Or
is that an unanswerable question?
