NOTES ON THE COPEPODA OF THE 



AVlicn the Copepod species of the warm area of the North Atlantic 

 are examined it is seen that there is not a single species which is 

 purely epiplanktonic. For long it has been considered that Anomaloccra 

 Patcrsoni was a purely surface species, but the capture of an adult 

 male example in a bottom scraping at 400 fathoms, in perfect condition, 

 shows that it can sometimes descend to considerable depths. 



Lonyipedia coronata, an Harpacticid of supposed purely littoral 

 habit, is shown also to exist at great depths, having been taken in 

 scrapings of the bottom at 400 and 500 fathoms respectively.
