Hello Harry,
The Neue Mannigfaltigkeiten was published by F.H.W.Martini between
1774-1777 and is available online.
The reference you're looking for:
http://www.ub.uni-bielefeld.de/cgi-bin/neubutton.cgi?pfad=/diglib/aufkl/neuemannigf/153771&seite=00000436.TIF
The title of the article:
Fortsetzung der vorläufigen Nachricht und Abbildung einiger
linksgewundenen Schnekken. (mit Illustr.)
translated:
Continuation of the preliminary communication about and illustration of
some lefthanded snails (with illustr.).
It's quite a large article and it is written in German Fraktur print,
which for modern eyes isn't easy to read.
I still hope that this still helps you further with your research.
Sincerely, Erick Staal
