1959-1960 xii, 834 p., 2516 figs, half calf with cloth covered boards. Ex library Dr. A.C. van Bruggen (with his signature). Very good copy of this huge and important work started by Wenz (first two parts appeared in 1938-1944). But Wenz lost his library and collections, during the bombings on Frankfurt at the end of the war. As Wenz died in 1945, Zilch had to finish and update Wenz’s manuscript which took longer as expected.We added: Zilch, 1966. Berichtingen zum Handbuch der Paläozoologie. Band 6 Gastropoda. Teil 2 Euthyneura (5 p., 1 fig.).
1974 58 p., 1 fig., 4 pls, stapled. Published in: Archiv Molluskenkunde. Ex library Dr. A.C. van Bruggen (with his stamp).We added two other papers published in Arch. Moll. by Zilch: Microna Ziegler in Frauenfeld 1863 ((3 p.) & Landschnecken aus Peru (11 p., 12 figs, 2 pls).
