On the north side of Beeren Island it has been met with at the depth of 165. Text-fij;. Q The finds of Pcrigoniiniis abyssi ill the Northern Atlantic. metres (Bonnevie 1899). In Arctic regions it may occur in considerably shallower waters. Thus the German expedition to Spitzbergen in 1898 found the species in the Storfjord at the depth of between o and 10 metres (Broch 1909), and certainly it is the same species that is recorded by Kramp (1911), by the name of Pcrigonimns sp., from the depth of 20—40 metres at a couple of stations of the "Dan- mark" Expedition. To the localities previously recorded must now also be added the west coast of Greenland near Egedesminde. — According to the data in hand, the species must be characterized as Arctic and boreal (Text-fig.
