London, Taylor & Francis, 1908-1921. Four parts in four. 8vo (22.8 x 15.8 cm). More than 1,500 pp.; two plates, numerous text figures. Uniform red cloth with gilt titles on spines. Black endpapers (white in Vol. II).

Seldom-seen original editions of still the most important malacological contribution to India and neighbouring countries. Not to be confused with the cheap, poorly copied "reprints". With many figures in the text (shells, radulae, anatomical details). Part I (Testacellidae and Zonitidae) ,W. T. Blanford & H. H. Godwin-Austen (1908), xxxii, 311 pp., 90 text figs.; Part II (Trochomorphidae-Janellidae) G. K. Gude (1914), xii, 520 pp., 164 figs.; Part III (Land operculates, Cyclophoridae, Truncatellidae, Assimineidae, Helicinidae), G. K. Gude (1921), xiv, 386 pp., 42 text figs, 2 plates; Part IV (Freshwater Gastropoda & Pelecypoda) H. B. Preston (1915), xix, 244 pp. The fourth part preceded the third and is not internally listed as being the fourth. Part III is inscribed by the author (Gude) in the top margin of the title page. All with a stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the title page. Light wear to spine tops and corners, but in all an excellent set. Complete sets, such as this one, are definitely rare.
