Item ID 67766
Paris, J. B. Baillière et fils, 1856-1865. Large 4to. (24.5 x 30.5 cm). Text and atlas, in seven volumes. Text (in three parts): half-titles and titles, 2,550 pp. [912; 968; 668, (ii)]. Atlas (in four parts; viz. of the two volumes the plates and the explanations separately): two title pages, 195 [88; 107] pp. of explanatory text, and 196 large, finely engraved plates [I-LXXXVII, XIbis, XVIbis; I-CVII]. Original, nearly uniform printed wrappers to all parts except blind wrappers to the two plate volumes. One of the largest and finest works of the French malacologist and palaeontologist Gérard Paul Deshayes (1796-1875). As usual with works dealing with fossils, there was just one, uncoloured, edition. It was sold, in 1866, for 250 French francs: by far the most expensive of all uncoloured works on Mollusca. Only the hand-coloured edition of Férrussac and Deshayes' Histoire naturelle général et particulière des mollusques was more expensive, at 490 francs, discounted from a previous and astonishing 1250 francs. The fine plates with large, detailed figures, are by Delahaye, Formant, Lackenbauer, and Levasseur. Most specimens have a detailed enlarged illustration, a life-size outline figure, and, often, a further enlarged sculpture detail; in the bivalves usually the taxonomically important hinges. Like most of his works, this one is important because of the many new species and detailed illustrations. The Description is one of the few works completed by the author, and includes simple plate numbering. Deshayes started many projects, but several remained unfinished and the plate numbering, for instance in his work on the molluscs of Algeria, was usually confusing. In this work, however, there are only two "bis" plates. The last page of volume 3 contains a list of publication dates of the 50 livraisons, recording the first two as from 2 November 1856, and the last two (49 and 50) from 15 December 1865. Only the last title page and wrapper bear the year 1866. This work is truly rare, and possibly even Deshayes' rarest work. There are no auction records of complete copies after 1965, when Wheldon and Wesley purchased one at Sotheby's in London. Uncut, with the widest possible margins. The wrappers and titles to the two atlases have been bound with the explanatory leaves. The second and third text volume have the word "tome" printed, and "1er", and "2eme" added in an old hand, the first text volume has a wrapper with the printed text "tome troisième", the last word corrected in the same hand to "1er". A few small, isolated spots, but generally very clean, especially the plates. Nissen ZBI, 1089. Deshayes' magnum opus on the fossils of the Paris Basin, fine and excessively rare
