Volume 16 of the only really important natural history journal published on New Guinea. Despite the French title, this work is in German. This chiefly ethnographical volume consists of Part 1: Anthropologische und ethnologische Ergebnisse der Central Neu-Guinea Expedition, 1921-1922; Part 2: Untersuchungen an Schaedeln und Skeletteilen aus dem Gebiet der Humboldt-Bai und dem Suedlichen Kuestengebiet von Hollaendisch Neu-Guinea; Part 3: Beitrag zur Ethnologie der Sentaier (Hollaendisch Neuguinea); Part 4: Die Gemeinde der Gondara. The entire experiences of the scientists of the New Guinea Expedition between 1907 and 1936 are published in 21 volumes. Most parts are very rare. The series is also important for dealing with New Guinea's zoology, including much on entomology.
