Dear all, I need some more help on very rare shells.
Below is my list of trochidae I have gathered so far:
Calliostoma atlantis Clench & Aguayo, 1940
Calliostoma olssoni Bayer, 1971
Calliostoma aurora Dall, 1888
Now, I want to make five entries for each major family,
and as you can see here I only have three. Can someone
give me some suggestions on the other missing two? I would
prefer that they not be in the Calliostoma genus.
Thanks,
James
