October. At 59° N. 16° W. and 60° N. 4° W. 



The rare occurrence of this species to the north of S. Amer- 

 ica can be accounted for by the South Equatorial current, 

 especially as it has been observed west of the Gulf of Guinea. 

 Otherwise this species is confined to the eastern Atlantic, in the 

 region of the Azores, whence it is conveyed in the spring towards 

 the Channel. In May it reached the north of Rockall, in June the 

 south of Iceland, whence it drifted towards east Green land and 

 the Shetlands.
