Prague, Musée Bohême, 1881. Four parts in four. Large 4to (32.8 x 26.0 cm). xxiv, 342 pp.; 361 lithographed plates with explanatory text leaves. Original uniform blind-tooled black cloth with gilt title on the spines.

Part of an enormous series on all aspects of Bohemian Silurian fossils, complete for the group covered. It was privately printed in only 250 copies. See Zittel, and DSB: "From 1840 to his death Barrande collected, described and drew the fossils of the central Bohemian Basin - this area has been called the Barrandian ever since. The strata of this basin are Proterozoic - early Paleozoic in age. At that time 'Silurian' might be applied to strata that today are in the Cambrian, Ordovician, Silurian or Devonian system. The results formed the outstanding monograph Système silurien du centre de la Bohème, which appeared in eight parts forming 28 quarto volumes". 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. Some isolated, mostly marginal foxing; otherwise a very good, clean, and unmarked set of this rare work.
