I have found these sites helpful: Although based in the Florida panhandle, they have links to other regions. http://www.jaxshells.org/ This one has multiple examples for most species. Very helpful for sorting through multiple possibilities. http://www.gastropods.com/ Southwest Florida - http://www.shellmuseum.org/ For local shells, Pacific Northwest, go here - http://members.shaw.ca/bcshells/shellcore.html To identify local genera, Kozlof's Marine Invertebrates of the Pacific Northwest is an excellent resource. Usually, I can get to the genus level and then I start looking through the images to find the "best bet" species. One could spend more than one can afford on books and still not be sure. I guess that is the appeal of studying these animals. -----Original Message----- From: Conchologists List [mailto:[log in to unmask]] On Behalf Of John Varner Sent: Wednesday, February 15, 2006 5:08 PM To: [log in to unmask] Subject: shell ID books I am looking to upgrade my shell collecting library. I have the Peterson and Simon & Schuster guides and Abbott's Compendiums of Land and Seashells. Does anyone have any suggestions for additional identification books or internet sources for shell ID info? -John Varner ---------------------------------------------------------------------- [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. ----------------------------------------------------------------------
