That's odd. Must be some problem (d'oh) but I can't think of what.
All messages should go straight into the list and wait there for
people to load. Who's running the list just now? (rhetorical
question). I can't think, but I'll forward your message and ask the
listmom to TRY to sort your problem out.

I HOPE these came from the dealer who sells them for low prices!!

Such as the one Poppe had in his "special shells" site.

Try buffering with calcium carbonate. If pateeliform, it might be
best to remove the animal carefully and dry the shell; retain the
preserved animal separately.

Yes, bad news. My Lamellaria steransii lost their shells to formalin.

Dratted thumbnails... when you drag & drop to copy, you get the
thumbnail... not the full-sized image, which must be LINKED. Cheapo
site! No taxonomic names either, just meaningless vernacular ones
invented on-the-spot...
Scissurellids are oddballs. Some (Anatoma, Scissurella,
Sukashitrochus, Sinezona) are pretty normal gems, but some have very
reduced slits only present in adults (Incisura = Scissurona, not a
fissurellid at all) and some have no slit at all (Larochea). I think
there's another slitless form being described presently. I'm very
interested in them and have NZ specimens of all of the above
described genera. Of overseas forms I only have Anatoma crispata from
the Pacific NW and and an unidentified Sinezona from the Society
Islands (quite likely undescribed) so far.
