xii Introduction 



Again we wish to acknowledge our gratitude to the Sears Foundation for Marine 

 Research, which has financed the publication. We are also grateful to the Woods 

 Hole Oceanographic Institution and the Museum of Comparative Zoology, which 

 have contributed in large measure to these publications through salaries to the authors 

 and through special grants for the preparation of illustrations and for travel to 

 examine specimens. We are likewise indebted to those institutions which have gener- 

 ously supported the work of the editors, particularly the Bingham Oceanographic 

 Laboratory, the American Museum of Natural History and the New York Zoolog- 

 ical Society. 



The Editorial Board again expresses its particular appreciation and thanks to 

 Yngve H. Olsen, who has edited the manuscripts and seen them through press with 

 untiring patience and enormous skill and to Henry Sears for his continued interest 

 and support. 



Finally, we note with profound regret the death of the late Dr. Samuel F. Hilde- 

 brand, who served the field of ichthyology so well and long and who gave so generously 

 of his time and experience as a member of our Editorial Board.
