animals have not all been identified. For example, few of the coelen- 

 terates, about 20 out of approximately 30 species of tunicates, and 14 

 of an approximate 21 species of copepods have been identified. 

 Literature on extent of the range of some of the animals was not 

 available, so that these data could not be given. For example, out of 

 21 species of decapods, i is new to the Arctic, 2 to the western Arctic, 

 I to Arctic Alaska, 4 to Point Barrow, i has been reported previ- 

 ously from Point Barrow, and exact data are lacking on 10 species. 

 By "western Arctic" is meant any place west of the American Archi- 

 pelago along the Canadian or Alaskan coast. "Arctic America" 

 excludes Greenland.
