I have several of these shells, and they are impossible to identify exactly. However, take a look at Eddy Hardy (he's pretty much up to date): http://www.gastropods.com/6/Shell_1026.shtml (nigrispinosus) http://www.gastropods.com/6/Shell_5776.shtml (ternispina) If you can't tell the difference, then join the rest of us. Perhaps there is a unique feature of one of them that differentiates, but otherwise, I think it is a question of synonymity that no-one has yet looked into. ---------------------------------------------------------------------- [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. ----------------------------------------------------------------------
