I found these citations in the Peterson Guides "Coral Reefs" and
"Atlantic Seashore" and in the "Audubon Society Field Guide to Seashore
Creatures". No authors are given:

Inflated sea biscuit - Clypeaster roasceus

Flat sea biscuit - Clypeaster subdepressus

Five-holed keyhole urchin - Mellita quinquiesperforata

Sea Mouse - this name is given to a polychaete worm, Aphrodita hastata.
Of course, that doesn't mean it could not be applied to an echinoderm
also - that's the problem with common names.

The California sand dollar might be the Common sand dollar,
Echinarachnius parma, although California is somewhat south of its
range.

Purple sea urchin - Strongylocentrotus purpuratus

Green sea urchin - Strongylocentrotus droebachiensis

I'm certainly no expert, but this will help.
