Paris and Strasbourg ("Parisiis et Argentorati"), A. Koening, 1806. One part (of four). 8vo (21.8 x 14.0 cm). xviii, 302, [1] pp, 16 engraved plates. Original marbled boards. Spine with printed paper label. = First part of one of Pierre André Latreille's most significant works, including all the plates. "While Latreille praised Cuvier for having founded zoological classification on comparative anatomy, he based his own classification work primarily on the consideration of external characters. Nonetheless, as one of his successors remarked more than half a century after the appearance of the 'Genera', the work offered "such an exact exposition of the characters of the insects, arachnids, and crustaceans, and nearly always such a just appreciation of the natural affinities of these animals, that the most modern researches only added rectifications of a second order" (DSB). This part deals with the systematics of crustacea (the first 72 pp.), Myriapoda, arachnids, Mecoptera, and Coleoptera (pp. 169-302) and has all the plates. Uncut. Wrappers rubbed and frayed at edges. Last plates with a marginal damp-stain, not reaching the figures. Otherwise a very good copy. Rare. DSB VIII, p. 48; Horn-Schenkling, 12835; Nissen ZBI, 2387.
