Thanks, Peter. I am slso trying to organise my collection, and your method sounds very economical of time. My shells are in boxes (well, Tupperware)on brought down from the shelves to my kitchen table, and it's looking a bit of a daunting pile. It's been there for 3 months now (but hell's bells, shell collecting is a leisurely pursuit, isn't it?). ---------------------------------------------------------------------- [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. ----------------------------------------------------------------------
