Clermont-Ferrand, Thibaud-Landriot, 1834-1836. Two papers in one. 8vo (21.6 x 13.7 cm). 166, [i] pp.; 16 pp.; two lithographed plates. 20th century half cloth over marbled boards. Spine with gilt title. Original printed wrappers of the first paper bound in.

Two seldom-seen malacological publications by the French malacologist and geologist Jean Baptiste Bouillet (1799-1878) on the faunas of a mountainous region in central France. The shorter half-title of the larger paper reads: " Catalogue des coquilles vivantes et fossiles de l'Auvergne". The second paper, published earlier (1834), being an offprint from " La description historique et scientifique de la Haute-Auvergne( Département du Cantal)" with title leaf, drop-head title, pp. [3]-16, and two engraved plates. These are two of several mid-19th to early 20th century French regional catalogues of non-marine molluscs. Almost every département had its own keen malacologist tackling the local malacofauna. Provenance: stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the first paper's front wrapper, otherwise clean, very good.
