First, I apologize for having offended any of you with this novice's abuse
of the nomenclature.  Obviously, "coreanicum" is merely the subspecies
nomenclature, for the local variety of Ceratostoma burnetti.  See
http://www.gastropods.com/Taxon_pages/TN_Family_MURICIDAE_OCENEBRINAE.html
.  When you click on the Ceratostoma coreanicum and it brings up the
pictures, it adjusts the nomenclature to show "coreanicum" as a subspecies
instead of a species.

Thanks for the notes about the de-scaler.  I will look into it, but it
probably is too expensive for my needs.  A collector in California who has
vast experience (and collection) of similar Murex uses a "sand"-blaster
with walnut dust to wonderful effect, he says.  That sounds more
affordable and may be more effective than the de-scaler.  I also will try
Lime-Away on a shell that is too defective to matter and determine how
well that works for spot cleaning.  Korea has some very strong cleaning
vinegar.  I soaked some of my heavily mineralized dug Chinese coins in
that vinegar diluted by half, was called to the phone briefly, and
returned to find one coin half-dissolved and the others well past the
point to which I wanted them treated.  Fortunately, they were early
Republic coins that I had dug in abundance, not my only Pan Liang, from
@220 BC.

Anyone who wants to see pictures of the Korean shells, send me an email
and I will provide the pictures.  I don't have a website.  Thanks, again.

Chuck
