Strom says it is called Suar by the Bergen folk, and that it 

 sticks so fast to fishes as to be often taken with them. Johnston* 

 says : " When at rest, this Oetopod lies prone on the belly, the 

 arms spread out in front, with their extremities exposed in 

 spirals on the sides. It has in this position a considerable like- 

 ness to a toad ; and, often raising the back and head, its aspect 

 is really repulsive and threatening. It moves quickly, and 

 always retrograde, playing its arms in a regulated, graceful 

 manner, which no one can contemplate without wonder in a body 

 so grotesque and apparently so inapt for locomotion." 



Northern and Atlantic coasts of Europe. 



Genus BOLIT^NA, Steenstrup. 



In the description of this genus no type is cited. In Wood- 

 ward and Keferstein a single living species is mentioned, but
