Jena, Gustav Fischer, 1910. 4to (34.5 x 26.0 cm). 61 lithographed plates (mostly in chromolithography), of which several double-sized, and their explanatory text leaves. Original quarter black cloth over printed, orange boards and matching original spine cover. Printed endpapers.

This is a beautifully illustrated part of Volume 18 of the Wissenschaftliche Ergebnisse and one of the first systematical monographs on Cephalopoda with all the fine plates and including the description of new, sometimes bizarre, species. The accompanying text-volume, hower, is not present. The printed endpapers contain an outline of the complete scientific results of the "Valdivia" expedition, with the published parts marked. Written by the German marine zoologist and malacologist Carl Chun (1852-1914), who initiated the Atlantic Plankton-Expedition der Humboldt-Stiftung (1889), and subsequently initiated and led the "Valdivia" expedition. This original German edition is very rare. A much later English edition has inferior plates. Some very light, marginal foxing, but generally quite clean. The original "Gustav Fischer orange" binding is in an excellent state. Nissen ZBI, 883, 4625.
