Okay, I didn't goof, my "computer" (keyboard working off our cable TV) recorded a wrong URL for my "bookmark."
The correct URL stands as before, viz:
http:/home.swbell.net/cbusch/stlshell/
The micros can be accessed by clicking on the "Can You..." on the left margin of the page. Use your zoom on them. The bivalve may be a Cardita. The red part of the spire on the otherwise white gastropod is part of the shell, not any type of attached marine growth.
