Abstract
The present report deals with the Quaternary marine deposits in West Greenland. The area in question extends from Kugssineq, Svartenhuk peninsula, in the north to the settlement of Sukkertoppen in the south. The field investigations for the paper have been made partly in 1939, partly in 1946, last-mentioned year under the auspices of Grønlands Geologiske Undersøgelse (abb. G.G.U., i. e. Geological Survey of Greenland). All localities visited are described with added lists of the collected shells. On the basis of the investigations made it will be demonstrated that the stratigraphy of the layers at Orpigsôq drawn up by Jensen and Harder in 1910 (30) is applicable to all the area investigated. Furthermore a detailed examination is made of the petrographic structure, the content af shells, and the levels of the various horizons, a discussion of a few errors, and ultimately an attempt at a correllation of the Quaternary marine layers of Greenland with the corresponding postglacial layers of Iceland, Norway, and Denmark.

Summary
All recent writers, who have dealt with the postglacial marine deposits in the Aretie, have fn und that a temperature higher than at present was prevailing at a certain tin in the polar region. The high-aretic horizon D in Greenland is correlated with the Arctic layer 3 in Iceland. As appears from the table the high-arctic horizon A has been eorrelated with tho younger Yoldia clay and the older Dryas in Denmark, the horizons B-C with the Zirphaea Sea layer and the desiccation horizons of the Allerød time, as a rise in temperature took plaee at that time, and horizon D with the younger Dryas clay, during the deposition of which a climatic deterioration again occurred.
