THE Harriman Alaska Expedition, during the months of 

 June and July, 1899, afforded exceptional advantages for the 

 investigation and collection of the marine invertebrate fauna 

 of the Alaska coast south of Bering Sea. 



During the course of the expedition collections of Nemer- 

 teans were made at Victoria (Vancouver Island) and Lowe In- 

 let in British Columbia ; at New Metlakahtla (Annette Island) , 

 Cape Fox, Wrangell, Farragut Bay, Taku Harbor, Juneau, 

 Skagway, Glacier Bay, Sitka, and Hot Springs on the islands 

 and mainland of southeastern Alaska ; at Russell Fiord and 

 Yakutat Bay; at Orca and Virgin Bay in Prince William 

 Sound ; at Kadiak ; at Popof Island, Shumagin group ; at 

 Kukak Bay on the Alaska Peninsula ; and at Dutch Harbor, 

 Unalaska.
