Dear Michael,  Have you seen quite a few of the two species?  I have
seen many of each and I see more differences than similarities.  I am
curious as to how much experience you have had with these species?
Since I do sell shells, I have many pass through my hands.  I first
started in the shell business after a trip to West Africa in the
seventies in which I bought a lot of shells, and many of them were Cy.
Stercoraria.  I brought back a lot of shells, so I went into business.
I think mus, teulerei, and fultoni look very similar.  That's my 2
cents.
