I posted more images of Neritidae, mostly Cymostyla, on my web page:
http://members.cox.net/cbankston/Neritidae.html

I have managed to identify most with the generous assistance of Tom
Eichhorst, but I have not yet had time to add the names to the web page.
  Before I do I would welcome comments on their identities from the
talented Conch-L crew.
