Systême Silurien du centre de la Bohême. Première partie: recherches paléontologiques. Continuation éditée par le Musée Bohême. Vol. IV (Tome II). Gastéropodes.

1907 xi, [1], 380 p., figures 112-264; 86 beautiful lithographed plates [plates 90-175] on thick paper with explanatory text-leaves, roy. 4to, publisher’s blind-tooled burgundy cloth with gilt title on spine. A few spots in the text, plates mostly clean. A good copy of this rare work.Part of a large series on all aspects of Bohemian Silurian fossils. Each volume was privately printed in only 250 copies. 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. At that time 'Silurian' might be applied to strata that today are in the Cambrian, Ordovician, Silurian or Devonian system. 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. The Cephalopoda (mostly ammonites) were described and figured in volume II, which consist of nine parts, and two supplements. All parts are rare. This is a third of the gastropod part (IV of the series), and includes many new species. Published well after Barrande's death (1799-1883), it was written by Jaroslav Perner, most new species, however, are attributed to Barrande, based on his manuscript names.
