consisting of ten males and one female), suggestive of the possibility 

 that the females were sitting on eggs nearby. The birds were seen at 

 close enough range to identify them as scaups, but whether Marila 

 mania or M. affiivis, or both, would, of course, have required the cap- 

 ture of specimens for determination. 



Glaucionetta islandica (Gmelin). Barrow Golden-eye 

 Seen at various points within ten or twelve miles of Telegraph 

 Creek : at the Summit, June 4 and 5, a flock of five females and several 

 single birds, both male and female ; at Sawmill Lake, occasionally dur- 

 ing June; and on a small stream south of Telegraph Creek. Two 

 females were shot at the Summit, June 5, and one of them was pre- 

 served (no. 39707). These two birds were evidently not breeding. 



The species encountered was apparently Glaucionetta islandica. 

 The identity of the one specimen saved was determined mainly through 

 a study of the characterization of the two forms, americana and islan- 

 dica, as given by Brooks (1920, p. 356). This decision, though, is also 

 influenced by the fact that the adult males seen were unquestionably 

 islandica, the triangular white facial patch being plainly discernible 

 with the binoculars. This is a curious instance, in which the identity 

 of a specimen in hand (a normal adult female) is confirmed by sight 

 identification of others not obtained. 



Histrionicus histrionicus (Linnaeus). Harlequin Duck 

 Not seen along the lower Stikine River, but fairly common along 

 the upper part of the stream. Frequently observed at close range 

 from the river boat, always seen in swift water, flying up when 

 approached too nearly, or perhaps swimming fearlessly through a 

 swirl of rapids alongside, paying little heed either to the boat from 

 whose path it just withdrew, or to the rocks and snags between which 

 it picked its way. Seen as far up the river as Telegraph Creek. 



Oidemia deglandi Bonaparte. White-winged Scoter 

 Undoubtedly nesting on Sawmill Lake, where varying numbers 

 were seen during the month of June. Twenty or more of both sexes 

 were noted on June 17, and lesser numbers on many 6ther occasions. 

 Not met with elsewhere.
