Plankton-type. This species belongs to the arctic and Nor- 

 thern Atlantic. I have met with it in a sample from the Bering Sea. 

 It has been seen in the west as far north as 74° N. From there 

 it follows the E. Greenland Current to Iceland, where it occurs from 

 April to November. From Iceland it goes round S. Greenland and con- 

 tinues with the southward current along America, at least to 38° N. 

 In the other direction ■ it spreads to the Faroes, Scotland, into the 

 North Sea and to the "VV coast of Norway, which it follows, and 

 continues round Spitzbergen and into the Murman Sea. In the E. 

 it scarcely goes south of 58^' N., but very rare specimens may drift 

 as far as the Azores. — T. and A^s.
