Dear Helmut,
   Although workers in the whole of Europe might use the name Cochlicopa,
Cionella is the correct name according to the rules of the International
Commission on Zoological Nomenclature. Of course, someone could write a
petition to the Commission requesting a ruling that would preserve the name
Cochlicopa over Cionella, but I don't think anybody has done that. Also,
even if someone petitioned, we don't know whether the Commission would
decide in favor of Cionella or Cochlicopa.
   I know that Schileyko used Cochlicopa in his monograph, but I have spoken
with him and I think he sees now that Cionella is correct.
   Yes, in North America we also have discussions about what the different
species of Cionella are.
   Best wishes,   -Tim-

Dear Tim,

In all our large European scientific works about the landshells is
Cochlicopa. This is the right Genus name as we use it in the whole of
Europe. Only the discussion about what is Cochlicpa lubrica, lubricella,
repentina. You can see this through anatomic and repentina is not an own
species. Cochlicopa lubricella is smaller, thinner as lubrica, but also the
southern specimens of lubrica in South Tyrol are smaller than their
representatives in North Tyrol. Cochlicopa lubrica lives at not to moist
places, in leaves, under old wood, under stones, on rocks with mould, in
forests and is mightbe the most common one. Cochlicopa lubricella lives on
quite dry places, as on sun exponed slopes eg, while the rare Cochlicopa
nitens (the broadest and largest of this Genus) lives in wet places, near
different waters, as lakes in reef, in marshes, eg.

Could you distibuite this message on Conch-l for me as I can't reach it at
the moment.

with best regards
