which are plentiful on the Island. Lying at anchor near one of the 

 cliffs we could see a number of these foxes threading their way along 

 the face of the precipice. 



Lagopus leucurus leucurus (Swainson). 



WHITE-TAILED PTARMIGAN. 



A few were seen in company with about three hundred L. rupestris 

 dixoni at Muir Inlet, Glacier Bay, Alaska, April 1 2, 1913. Two males 

 and a female were preserved. 



Dendragapus obscurus fuliginosus (Ridgway). 

 sooty grouse. 



Several were seen about Point Gustavus, Glacier Bay, April 11, 

 1913. A pair was taken. 



Gaviidae. 

 Gavia stellata (Pontoppidan). 



RED-THROATED LOON. 



This species was noted in small numbers about a large marsh on the 

 west side of Providence Bay, East Siberia, June 19 and 20, 1913. 



During the last week in June they were found breeding on the 

 southern side of St. Lawrence Island where two sets of eggs were 

 taken on June 27, 1913. A number of nests were found that appeared 

 to have been robbed by Glaucous Gulls. 



At Cape Serdze, East Siberia, several were seen July 17, 18, 1913. 



None were seen at Demarcation Point in 1914 until June 12, when 

 a female was secured. Though I could find no nests, two pair at least 

 remained in the vicinity of the Point during my stay. 



This species is the tamest of the loons and instead of stealing 

 quietly away when one is at their nest they fly immediately and circ- 

 ling about above one's head utter continually their harsh cry " kark- 

 kark-kark." This cry can be heard almost any time through the day 

 or night where this bird is breeding.
