Hi Ross:
Here are bib’s form the Echinoderm publications I have.
You mentioned Hawaii, my material is primarily Gulf/Florida Caribbean.

There is a new Australian book coming out, but apparently it is delayed at the
moment:  Miskelly, Ashley 200x - Sea urchins of Australia and the Indo-Pacific,
A detailed guide to all species known to occur in Australia. With detailed
descriptions, and colour illustrations of live urchins and dead tests.

BIB’s:  is a semblance of order of usefulness. (the 1st one is great)

Ok, so I know sea urchins are echinoderms, not Molluscs, but its a related
question.  Does anyone know of a book(s) that have ID's for sea urchin tests
(shells)?  I know I've seen one, but unfortunately I forgot where and didn't
think to write down any info on it (although I think it was a book on Hawaiian
inverts, I seem to remember Heterocentrotus mammillatus being in there).  I
have several urchin tests, and I know you can identify species by the patterns
of nodules, grooves, etc on them.  Anybody know of a place I can look to help
with that?  Thanks!
