PYCNOGONIDA. c 
Besides the stations mentioned by Hansen, Il. c, p. 23, from the south-western coast of Nova 
Zembla, the western coast of Greenland, the Finmark, and Kullen, it is found in the Zoological 
Museum also from the Davis Strait 65” 35' Lat. N. 54? 50' Long. W., 80 fath. (idem); the belt of rocks 
and islands outside Frederikshaab, 25 fath. (idem, and Lundbeck); in the Bredebugt (the Denmark 
Strait) 9 fath. (the lieutenant Jensen); in the Øfjord (the Greenland Sea) 15 fath. («Diana»). 
Distribution. The species is one of the most widely spread Pycnogonida, from the arctic 
seas quite down into the Sound, and towards the west from the Davis Strait along the eastern coast 
of America; it keeps, however, mostly nearer to the coast, and the depths are most frequently small, 
rarely more than 100 fath.
