ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 25 



Acknowledgements 



The Allan Hancock Foundation has continued to be the main 

 supporting institution for the study of the polychaetes of California ; to 

 its Administration I am deeply indebted not only for the facilities to 

 conduct these studies, but for continued financial aid. Some of the work, 

 both field and laboratory, was supported by the California State Water 

 Pollution Control Board, during the years 1955 to 1959. Some was 

 partly supported by grants from the National Science Foundation, in 

 connection with faunal studies of submarine basins and canyons off 

 southern California. Dr. J. Laurens Barnard, now at the Beaudette 

 Foundation, and Gilbert F. Jones and Robert Given at the Allan 

 Hancock Foundation, aided materially aboard ship and in the laboratory, 

 especially in sorting the samples. Mrs. Dorothy Halmos, Editor of 

 Publications, has continued her careful coordination in proof-reading and 

 editing. Anker Petersen prepared the plates of illustrations. I am deeply 

 indebted to all these people for their interest, help and encouragement.
