One of the most important contributions to the knowledge of the molluscs of the extreme Far East, and in particular Siberia. Written by the German-Russian explorer and naturalist Peter Leopold Ivanovich von Schrenck [Schrenk] (1826-1894) and based on material he personally collected. This work forms a part of a much larger work, which contains a travelogue, and a volume on the natural history. Of the latter, this is by far the largest part, and it is complete for the malacology. Partially coloured copies are known, but this work is rare in any state. The copy of the American malacologist and malaco-historian Richard Irwin Johnson (1925-2020), with his stamp on the front free endpaper and half-title top margin. Uncut, with the widest possible margins. Two text leaves partly browned due to an ancient insertion of a low-grade paper leaf; a few spots, but generally in very good condition. Nissen ZBI, 3750.
