Picture 3: Right side, Cypraea spadicea, identified in a previous post.  At front, Olive incrassata, family Olividae.  Along the left side of the box appear to be small cowrie shells, probably Cypraea annettae, though a better picture would be necessary to verify.

Picture 4:  front, Turritella gonostoma, family Turritellidae; rear, Pteropurpura trialata, family Muricidae, possibly with a couple of specimens of some other murex mixed in.
