Exceptional opportunity! Shell in F++ condition with nearly perfect perio. This very rare morph was traced in the city of Halle in October 2014. Unfortunately extinct by reconstruction of a building. I tried to breed some survivers to save this population but failed in F2 generation. No more around. Very exact locality comes with the shell. I tend to determine this morph as albinistic rather than erythristic. Some shells show a slight rose tinge like this one does. Photograph from living animals is only to show environment and how shells of this population look with animal inside. If wished high res. pictures will be sent to successful bidder.
