Capt. Blakiston 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. Boss mentions Faffinis as abundant on 
on the Mackenzie to the Arctic Circle. 
Fulix collaris. 
Specimen from the Saskatchawan ( f Fauna Bor.-Am.’), under 
the name of Fuligula rufitorques, and from Fort Simpson, on the 
Mackenzie. 
111. Aythya vallisneria. 
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. Boss does not note A. vallisneria north of Great 
Slave Lake. 
112. BuCEPHALA 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 f Fauna Bor.-Am.’ as Clangula vulgaris. Mr. Boss 
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 Bocky Mountains, as Clangula barrovii. 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. Boss gives it abundant on the Mackenzie, 
to its mouth.
