Hello All, If anyone has an extra-large operculum from Pleuroploca gigantea or Syrinx aruanus that they don't need, and would like to trade for some nice shells (or sell), I would be interested. This doesn't have to fit a particular shell - it is to be displayed "as is", as part of an instructional program; so it is strictly a case of "the bigger the better". I have a 105 mm Pleuroploca operc, so am looking for something bigger than that. I could also use an extra-large operc from Turbo marmoratus or Turbo jourdani, larger than 70 mm. So if you have a giant that you are currently using for a doorstop or paperweight, and would like to exchange it for more than its value in specimen shells, e-mail me privately. Thanks Paul M.
