Habitat. British Seas. — All round our coasts, but scarcer 

 in the south (Norman) ; Isle of Man (B. M. Coll.) ; Firth of 

 Cromarty (Copenhagen Museum). It was found by the 

 " Knight Errant" and " Triton," in the Faroe Channel ; depths, 

 53 to 560 fathoms (Lyman, Hoyle). It appears to be rather 

 more abundant in the shallower waters. 



Other Localities. — Norwegian coast, down to 200 fathoms 

 (Norman) ; Barents Sea (Hoffmann) ; Spitzbergen (Liitken) ; 

 eastern and western shores of Greenland (Lutken, Duncan 

 and Sladen). It has been dredged off the north-east coast of 

 North America, both by the " Blake "^ and the " Challenger;" 

 depths from 80 to 300 fathoms.
