A rare work on the highly diverse malacofauna of Lake Baikal, one of the oldest lakes in the world and a true example of evolution. The author, the Polish-Russian malacologist Wladyslaw Dybowski (1838-1910) describes and illustrates many new species and genera. Small stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the title page. Some wear to the board edges; text pages with mostly marginal foxing, first plate foxed, but the others nearly clean, and in all a very good copy. Cat. BM(NH), p. 500. Not in Nissen.
