Dr. Sturm,
 
Thank you for your advice.  However, I was aware of this article.  I have not read
it, and that is why I didn't say it was wrong.  I did say it sounded almost
unbelievable to me, and that was an opinion.  My opinion was partially based on
communication with divers who have collected both species and claim that the two
don't occupy the same habitat.  I have been collecting shells since I was eight, so
I have seen mistakes by malacologists before.  I don't immediatley take the word of
a man as truth, merely because he has a few letters after his name.
 
Regards,
