First supplement to a series of malacological papers by the French malacologist Louis Germain (1878-1942) based on the collections of Henri Gadeau de Kerville (Mollusques terrestres et fluviatiles de Syrie [1921-1922]), published in the Mémoires présentés a l'Institut d'Egypte. This supplement written by the French-Algerian naturalist Paul Pallary (1869-1942) who was an important malacologist and shell-dealer in Northern Africa. Although Germain's work was very rich in new data, Pallary was able to contribute another sizable addition after visiting the region himself. Includes several new species of continental molluscs, chiefly land snails. The plates mainly depict species of Mastus, and Clausilia (s.l.), but also Helicidae, Unionidae and others. Uncut. Stamp on front wrapper and series title; light fraying at edges; otherwise, a very good copy of a rare work.
