Philadelphia, PA, The Academy of Natural Sciences of Philadelphia, 1859. Loose in issues. 8vo (24.8 x 15.2 cm). xi, xxiv, xii, 353, 20, 20 pp.; four lithographed plates including two that are finely hand-coloured. Without wrappers (not issued), as published.

The ANSP Proceedings were the foremost zoological journal in the U.S.A., being especially strong in ornithology (here with important publications by John Cassin, vertebrate palaeontology, and molluscs. Malacological authors in this early volume include William More Gabb (1839-18789), and Isaac Lea (1792-1886). The hand-coloured plates shows new birds described by the American ornithologist John Cassin (1813-1869). Pagination is a bit complicated. For instance, Gabb's malacologically important Catalogue of the invertebrate fossils of the Cretaceous Formation of the United States, with references, has its own pagination (20 pp.). Uncut. Published without wrappers. A good, complete volume. Rare.
