Distribution in General: 



The distribution of this remarkable animal offers much of great interest. A 

 glance at the above-enumerated localities reveals that it inhabits the Arctic and 

 Baltic Seas solely. It is never obtained from the west coast of Norway nor from the 

 coast of Bohuslän and Halland in Sweden. To my knoledge too, it has never been 

 dredged up off the coasts of Iceland nor off those of the British Isles. As early as 

 in 1863 Loven refered it to the relicta forms. 



Regarding its distribution in the Arctic regions, the Halicryptus does not seem 

 to occur west of Greenland and the southernmost locality in those regions, where 

 it has been noted, is Klosterelv in East Finmarken (Norman 1903). 



In the Baltic Sea the species occurs in great abundance. Besides the above- 

 enumerated localities, it is met with between Weichselmunde and Heubude (v. Siebold 

 1849), off Hiddensee (Ehlers 1861), in Travemunder Bucht (Lenz 1878), and in 

 Kieler Bucht and Hohwachter Bucht (Fischer 1895). The northern limit of its
