ACKNOWLEDGEMENTS 



Many people took part in these studies and helped on board ship as 

 well as in the laboratory. In particular. Dr. Richard Backus of the Woods 

 Hole Oceanographic Institute was in charge of the identification of material 

 from the earlier collections; Dr. Basil G. Nafpaktitis of the University of 

 Southern California identified the lanternfishes of the genera Diaphus and 

 Loblanchia; Dr. Giles W. Mead of the Museum of Comparative Zoology at 

 Harvard identified the specimens of Pterycombus broma; Mr. Ronald C. Baird, 

 also at Harvard, checked the identification of the hatchetfishes, family 

 Sternoptychidae; Mr. Bert N. Kobayashi of the Scripps Institute of Oceanography 

 identified the fishes of the genus Cyclothone ; and Dr. Robert H. Gibbs, Jr. 

 and Dr. Stanley H. Weitzman of the United States National Museum checked 

 the identification of many of the other bathypelagic fishes. 



To all these people we extend our sincere appreciation. In addition 

 we thank our colleagues for many stimulating discussions concerning inter- 

 pretation of the data.
