Frankfurt am Main, Senckenbergische naturforschende Gesellschaft, 1890-1891. Two parts in one. 8vo (22.1 x 15.4 cm). 115 pp. [37; 78]; four [2; 2] lithographed plates. Disbound.

A rarely seen complete copy of an important contribution to Indo-Malayan malacology, by the German malacologist Oskar (or Oscar) Boettger (1844-1910). The fine plates are by the author himself. The German zoologist (chiefly nematologist) Adolf Wilhelm Strubell (1861-1927) travelled in 1889 to Java and the Moluccas, collecting shells for his father, the malacologist Adolph - or Adolf - Bruno Strubell (1831-1902), who had one of the most important private shell collections in Germany (see the introduction by Boettger), and published on new molluscs. The younger Strubell must have had a keen eye for land snails, as many species were new or poorly known. Boettger gave three new species the epithet strubelli, dedicating one new species to Bruno, one to Adolf, and one undetermined. The second part concludes with an index to both parts. Extracted from the society's Berichten. Not bound, but, otherwise, a very good, clean copy. Especially the second part seems to be rare.
