Systême Silurien du centre de la Bohême. Première partie : Recherches paléontologiques. Vol VI. Classe des mollusques, orde des acéphales [...].

4 vol., 4to: xxiv-342 pp.; 361 pl. (some staining, few isolated, mostly marg. spots).

Contemp. uniform blind-tooled burgundy cloth, gilt titled spines.

Part of an enormous series on all aspects of Bohemian Silurian fossils. It was privately printed in only 250 copies. Because this work is so comprehensive, its drawings so accurate and its descriptions so fine, it is still used as a reference book by palaeontologists. This is the complete Bivalvia-section (VI of the series), and includes many new species. Ill. with 361 lithographed pl. (48, 106, 100, 107) with explanatory text leaves.
