A rare, finely hand-coloured copy 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). 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. Rare. We found no auction records. OCLC reports 10 copies at most. Provenance: stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the front free endpaper recto and title. A photocopy of the first original front wrapper bound in; otherwise, very good, clean copy. Nissen ZBI, 4173.
