Does anyone know where I can find the article or articles that describe the morphological differences between Spisula solidissima (Dillwyn, 1817) and Spisula raveneli (Conrad, 1831)? I believe both are supposed to occur in Massachusetts (solidissima for sure, and raveneli I belive as far norht as Cape Cod) and I want to go through my collection and see if perhaps I have both (and want to know what to look for in the future to seperate the two species). If anyone can provide with or point me to any information (or even pictures) distinguishing the two species, would be greatly appreciated. -Thank you, Kevin **PS, if anyone wishes to email me directly, please use: [log in to unmask] ---------------------------------------------------------------------- [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. ----------------------------------------------------------------------
