Introduction 



The material upon which this study is based was collected by G. E. 

 MacGinitie in the vicinity of Point Barrow, Alaska. His work on the 

 invertebrates of the region (see G. E. MacGinitie, 1955j was spon- 

 sored by contracts (N6-0NR 243-16) between the OfRce of Naval 

 Research and the California Institute of Technology (1948) and The 

 Johns Hopkins L^niversity (1949-1950). The writer, who served as 

 research associate under this project, spent the. periods from July 10 

 to Oct. 10, 1948, and from June 1949 to August 1950 at the Arctic 

 Research Laboratory, which is located at Point Barrow base at ap- 

 proximately long. 156°41' W. and lat. 71°20' N. 



As the northernmost point in Alaska, and representing as it does a 

 point about midway between the waters of northwest Greenland and
