Dear conchlers
In 1987 I've got by an Italian friend
Prionovolva castanea Cate, 1978
from Nabeul / Tunesia.
leg. Bini, 12. 1984
But I didn't find this shell anywhere and so I don't know if
it is a good species, maybe common or rare. Hope that
somebody can answer me.
yours Helmut Nisters from Innsbruck, Austria
