Philadelphia, PA, The Conchological Section of the Academy of Natural Sciences1870. 8vo (22.1 x 14.4 cm). 238 pp; 17 lithographed plates in double suite: hand coloured, and tinted (for a total of 34 plates) [ Paludina 12-17; Limnea 16-18; Physa 6-9; Planorbis 5-7; Ancylus 2.] Later blue buckram with gilt title on the spine. Speckled edges. Original wrappers bound in.
The very rare double-suite edition of a continuation of the first major work exclusively on the freshwater snails of North America, written by the American malacologist George Washington Tryon (1838-1888). Originally published in four parts. The four original wrappers are all present. As stated in the title, this work is subsequent to a work by another American malacologist, Samuel Stehman Haldemann (1812-1880), hence the peculiar plate-numbering. Provenance: stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the front free endpaper recto and title. First front wrapper partly torn and rebacked; title page with two faint stains, and the top outer section of the pages towards the end ever so slightly cockled. Otherwise a very good, clean copy. Only three auction records found in the last 100 years. A handful of libraries around the world, mostly in the USA, have a copy and not always in the hand-coloured edition. We could not find a single double-suite copy anywhere else, or ever on the market before. Nissen ZBI, 4173.
