DESCRIPTION OF COLLECTIONS MADE CHIEFLY 

 NEAR KADIAK, ALASKA

 DISTRIBUTION 



THE collections here described and discussed are from 

 three principal localities : Woody Island, Pogibshi Island, 

 and the shore of Russell Fiord near Hidden Glacier. 

 Pogibshi Island lies close to the village of Kadiak, being 

 separated from the much larger Kadiak Island by the nar- 

 row strait constituting Kadiak Harbor. Woody Island is 

 a few miles distant, Woody and Pogibshi being members 

 of a group of low islands constituted wholly of slate. 

 The Hidden Glacier locality is nearly 500 miles to the 

 eastward. A fourth locality, about 300 miles northeast

 by a specimen from the back of Columbia Glacier, Prince

 that near Hidden Glacier, the containing formation has
