Distribution. — This species is an oceanic form widely distributed in 

 the tropical xitlantic and Pacific Oceans. It was actually first 

 recorded from American waters by the Challenger, which collected 

 it in the North Atlantic Ocean off the American coast and also off 

 the coast of Chile. In 1926 I gave a further list of localities in the 

 western Atlantic between Chesapeake Bay and the Bermudas, all 

 near the American coast. The above list of captures shows that the 

 species is not rare in the oceanic waters off the east coast of America, 

 where it is generally caught at or near the surface at night.
