Introduction. 



The trip undertaken by Mr. Johan Keren alon<,' the Arctic coast 

 of East Siberia, west to the Kolyma River, upon the results of which 

 this paper is based, was made possible by the enthusiasm and 

 generosity of Mr. John E. Thayer. 



In 1911 Mr. Koren, who had been collecting for Mr. Thayer on 

 the Alaskan coast, sailed north with his vessel (a fairly good 

 schooner), his crew, and outfit, and passed through Bering Strait in 

 the summer, and around East Cape. He headed for the Kolyma 

 River, to winter there, in order to collect in the spring in this 

 interesting region, where larch forest occurs, and where in conse- 

 quence there is a much more varied fauna than in other adjacent 

 parts of Siberia. 



In the spring he had one short month in which to collect, and 

 then on June 21 he set sail again on the return journey, which 

 necessarily was hurried, in an attempt to get through Bering
