148 Capt. Blakistou on the Birds of the 



son's Bay, whence I have also received specimens ; and on the 

 Saskatchawan I shot one or other of these two species, but was 

 uncertain which. Mr. Ross mentions F. affinis as abundant on 

 on the Mackenzie to the Arctic Circle. 



FULIX COLLARIS. 



Specimen from the Saskatchawan {' Fauna Bor.-Am.'), under 

 the name of Fuligula rujitorques, and from Fort Simpson, on the 

 Mackenzie. 



111. AyTIIYA VALLISNEllIA. 



My specimen, from Fort Carlton (' Ibis,' vol. iv. p. 10), is re- 

 ferred to the Canvas-back ; and in the ' Fauna Bor.-Am.' one is 

 also given from the Saskatchawan. The Pochard is also men- 

 tioned in that work, but there is no note of the locality of a 

 specimen. Mr. lloss does not note A. vallisneria north of Great 

 Slave Lake. 



112. BUCEPIIALA AMERICANA. 



First seen at Fort Carlton in the spring, on the 10th of April 

 (* Ibis,' vol. iv. p. 10); specimens also from Hudson's Bay. In- 

 cluded in the ' Fauna Bor.-Am.' as Clangula vulgaris. Mr. Ross 

 notes the Golden-Eye on the Mackenzie to the Arctic Coast. 

 One distinctive mark given between this and the following spe- 

 cies is the absence of a black band across the white of the wing. 

 Mr. Yarrell, however, figures both male and female with this line 

 quite distinct ; and if this is constant in European specimens, 

 it is a good distinction between C. vulgaris and C. americana. 

 There is a male specimen, however, in the British Museum, from 

 Nova Scotia, which has the black band on the wing very distinct. 



BUCEPHALA ISLANDICA. 



Described in the ' Fauna Bor.-Am.,' from a specimen killed 

 in the Rocky Mountains, as Clangula barruvii. This specimen 

 is now in the Museum of the Smithsonian Institution at Wash- 

 ington. 



113. BuCEPHALA ALBEOLA, 



Specimen from the Saskatchawan (' Ibis,' vol. iv. p. 10) and 

 Hudson's Bay. Mr. Ross gives it abundant on the Mackenzie, 

 to its mouth.
