Grammaria abietina is a typical arctic-boreal species, recorded also in a single instance (Bil- lard, 1904 p. 164) from the north of France. It may at times penetrate down to great depths, as for instance at the "Iugolf" St. 92, where it reached 976 fathoms, the greatest depth hitherto recorded for this species. Otherwise it is chiefly found (see fig. VI) in the deeper parts of the littoral regions of the boreal and arctic area. Grammaria abietina is also apparently an Atlantic species; it is known from the east coast of North America, to Taimur, but has not hitherto been recorded from about Bering Strait or the Pacific. If, however, it should prove correct that Grammaria scandens Stechow is a synonym for Grammaria abietina, then it must be classed among the circumpolar Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ingolf (Cruiser); Danish Ingolf-Expedition (1895-1896).
