A conchologist I once met here (Siargao Island, Philippines) collected chitons and popped each into a jar of glycerine/alcohol. Later, he taped each between two microscope slide glasses to flatten them, and let them dry out. I think this might work with bivalves. PS - I met him 10 years ago, so I can't really vouch for the long term efficacy of the treatment. ---------------------------------------------------------------------- [log in to unmask] - a forum for informal discussions on molluscs To leave this list, click on the following web link: http://listserv.uga.edu/cgi-bin/wa?SUBED1=conch-l&A=1 Type your email address and name in the appropriate box and click leave the list. ----------------------------------------------------------------------
