Certainly common all over the area, even though it is noted only 

 by BESSELS from the northern part. KANE and HAYES, according to 

 DURAND, have found it "in every station" and, for my own part, I found 

 it abundantly in Foulke Fjord, in all grassy ledges, slopes and plateaus, 

 etc. I will, however, enumerate the special localities reported in lite- 

 rature.
