Hi There is another site with unknown species, mainly from America. I have put 10 different land and freshwater molluscs on this site. Your help would be appreciated. I follow the mails via Conch-L Archive. There is something wrong with the connection to middle europe. I say thank you all who looked at the Thai gastropods. I see it is very difficult to determinate this species. I got a lot of different names. I hope the discussion is continuing after the e-mail connection is recovered. regards Wolfgang http://ipp.boku.ac.at/private/wf/NEU/Unbenannt_USA.html Wolfgang Fischer Institut fuer Pflanzenbau u.
