Certainly common all over the area, even though it is noted only 
by Bessets from the northern part. Kane and Hayes, according to 
Duranp, 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.
