1904-1913 34 [12 (i), 21] p., 110 [45, 65] plates with explanatory text leaves, folio (32.0 x 25.0 cm). Original printed wrappers.Rare complete set in the original wrappers of this famous atlas of Eocene molluscs (and brachiopods) from the Paris Basin. Mainly from Lutetien, Bartonien and Cusien stages, these faunas are known to be extremely rich and well preserved. A few species are introduced here as valid names, in particular on the last plate of volume 1 "supplément". Around 1900, the French palaeontologist and malacologist [Alexandre Édouard] Maurice Cossmann (1850-1924), was the leading expert on the Eocene Mollusca. He had an enormous amount of material at his disposal which accounts for the quality of the photographed specimens. Pissarro was responsible for the fine photographs. A smaller, printed leaf, "Avis aux souscripteurs" has been added. A few short tears in the wrapper edges, otherwise a very good, clean set.
