FOREWORD 



Dr. C. McLean Eraser passed away at his home in 

 Vancouver, Canada, December 26, 1946, while this paper was 

 in press. After completing this paper for the Allan Hancock 

 Foundation Dr. Fraser began work on the last shipment of 

 hydroids from the Pacific Expeditions. Early in December he 

 wrote that he had co?npleted the taxonomic paper to be the 

 no. 5 paper of volume 4, Allan Hancock Pacific Expeditions, 

 based on the studies of hydroids of the Pacific which form most 

 of the Allan Hancock Foundation collections. The no. 6 paper 

 luas to have been an analysis of distribution of hydroids in the 

 Eastern Pacific for the same volume. 



Considering the great debt that the Foundation owed to 

 Dr. Fraser for all of his assistance since 1934 when he began 

 his work with us, a summary of his tremendous contribution in 

 the field of hydroid research will be included in the same 

 volume with his final paper to be published later this year.
