102 GEOLOGICAL SURVEY OF CANADA. 



Island. Two immense blocks of rocks had become detached from 

 the cliff above, and when they fell their edges formed a hollow 

 place beneath. Under these rocks I discovered a deserted nest, 

 which the native who was with me asserted was that of a bird of 

 this species. The form was similar to that of the nest of H. 

 hyemalis, and in fact so closely resembled it that I persisted in it 

 being of this bird until the native asked me if I did not know 

 that the " Old Squaw " did not build in such places. (Turner.') 



MUSEUM SPECIMENS. 



Two specimens. One procured in Hudson Bay by Dr. R. Bell ; 

 the other shot at Banff, Rocky Mountains, by Mr. W. Spread- 

 borough. 



LIV. CAMPTOLAIMUS Gray. 1841. 



156. Labrador Duck. Pied Duck. 



Camptolaimus\ labradorius (Gmel.) Gray. 1841. 



Now extinct. Formerly abundant on the Labrador coast. Mr. 

 William Dutcher, in an able paper published in The Auk, for 

 January, 1894, shows, although 1852 has been given as the date 

 when the last specimen of this species was killed, that, from 

 that date to 1875, occasional specimens were taken and vouched 

 for as being seen in the flesh. He can find no trace of the bird 

 being seen since 1875 so that he reluctantly concludes it is extinct. 



LV. ENICONETTA Gray. 1840. 



157. Steller's Duck. 



Eniconetta stelleri (Pall.) Gray. 1840. 



The coasts and islands of Behring Sea may be given as the 

 eastern range of this duck. Westward from there it breeds 

 in tens of thousands on the coast of Siberia. Throughout the 

 Aleutian chain it is a common resident, very abundant in winter, 

 but less common in summer. It also breeds upon St. Lawrence 

 Island and a nest has been taken on Unalaska. {Nelson.') This 

 duck is rare at St. Michael ; on the southern and eastern shores 

 of Bristol Bay and the northern shores of Alaska it is plentiful. 

 Among the Aleutian Islands it is rarely seen in summer, in winter
