AGASSIZ, Jean Louis Rodolphe (1807-1873). Recherches sur les poissons fossiles. Neuchâtel: Petitpierre for the author, 1833-1843-. 10 volumes bound in 6. Text volumes with letterpress half-titles and errata leaves in volumes II and III, plate volumes with lithographic half-titles in vols II and IV and lithographic titles, and lithographic table. 402 lithographic plates by Diekmann, Jäger et al. after C.

FIRST EDITIONS. 'ONE OF THE EARLIEST AND MOST AUTHORITATIVE TREATISES, BY THIS FAMOUS NATURALIST, especially valuable as a textbook on European fish fossils' (Wood). Recherches 'contained precise descriptions of more than 1,700 ancient species, together with illustrated reconstructions based on principles of comparative anatomy. This pioneer effort was a model of exactitude, providing future students with primary data relating to zoology, geology, and paleontology' (DSB I, p.73). BM(NH) notes that the Monographie was 'regarded by the author, and given by Engelmann, as a supplement to the Recherches' (I, p.18). (6)
