Notes.

Paris, Société géologique de France, 1862. 8vo (22.8 x 14.1 cm). 25 pp. [numbered 721-745]; table. Original blind wrappers. = From 1840 to his death Joachim Barrande (1799-1883) 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. However, Barrande effectively published two series within his "Système Silurien". The second, of which this is an example, a series of zoogeographical, and phylogenetic papers and monographs on octavo format. Confusingly, several of the quarto volumes were published in octavo as well. This publication is an offprint from the society's Bulletin, 2nd series, Volume 19. Uncut. A very good, clean copy. Rare.
