According to Mr. Levinsen (12, p. 148) Periphylla hyacmthina 
has been found at several places on the coast of Greenland, and it 
is not impossible that an unusual expansion of the Fast Iceland- 
current may have carried the arctic medusa to our coast (January, 
1899). 
It should be remembered that in November 1898 UClione limacina 
occurred in the Puddefjord.
