Halitholus cirratus is an arctic medusa. It is very common at Spitzbergen, where it is found in June, July, and August, more sparingly occurring in the Barents Sea. In the present paper it is for the first time recorded from the west coast of Greenland, where it seems to be rare. In the deep, cold basins of tlie Baltic it is an arctic survivor; it is very abundant and occurs throughout the summer. It is somewhat less common in the Danish Belts and in the Kattegat, though it occurs in moderate numbers every spring from February to April; it is very rarely obser\-ed in May, because it disappears when the temperature of the water exceeds about 6° C, also hereby revealing its character as a well-marked cold-water species. — The find of a number of specimens, at the north coast of Alaska (Bigelow 1920) shows that the species has a 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 Danish Ingolf-Expedition (1895-1896); Københavns universitet.
