Helgelandskysten, og. den 3die (St. 200) NV af Finmarken ; 
Hybden 350 til 620. 
Artens for Tiden bekjendte Udbredningsfelt er her- 
•‘bcr det 0stlige Afheld mod Nordhavets store Dyb fra. 
•Hn 63de til omtrent den 72de Bredegrad. Den er utvivl- 
s °mt at betragte som en arktisk Form. 
(Stat 31) lay off the Storeggen Bank, the 2nd (Stat. 124) 
west of the "coast of Helgoland, and the 3rd (Stat. 200) 
north-west of Finmark; depth ranging from 350 to 620 
fathoms. 
Thus, the tract in which the species is at present 
known to occur, comprises the eastern slope of the sea-bed, 
where it shelves toward the great depths of the Northern 
Ocean, from the 63rd to nearabout the 72nd parallel of 
latitude. The animal should unquestionably be regarded as 
a true Arctic form.
