Euphausia americana has only lately been instituted by HANSEN, and appears to 

 have been confused hitherto with E. Krohnii, to which it bears a considerable resem- 

 blance. It seems clear that some of the Cliallenger specimens referred to E. pellucida 

 by SARS in reality belong to the present species. HANSEN gives as the locality for 

 this species, West Atlantic, Cape Verde ; but the above list of captures shows that the 

 species has a very general distribution in the tropical parts of the Atlantic Ocean.

All the specimens were taken in surface tow-nettings. The majority are post-larval 

 in development, but appear to belong to this species. 



E. recurva is known from the South Atlantic, Indian Ocean, and from two or three 

 localities in the Pacific (HANSEN, 1912).
