The collections and observations at sea have been taken by a 

 large number of individuals from the Scripps Institution of Oceanography 

 of the University of California and the California Department of Fish 

 and Game, as well as from the South Pacific Fishery Investigations. It 

 is a pleasure to acknowledge the wholehearted cooperation of all par- 

 ticipating agencies.
