39, Dendrceca estiva. 
A specimen from Fort Carlton Ibis/ vol. iv. p. 4), and my 
having observed it from near Hudson's Bay, all the way to 
the eastern base of the Rocky Mountains, denote the Yellow 
Warbler as widely distributed throughout the interior; while 
Hr. Richardson and Mr. Ross have recorded its abundance to 
the Arctic Circle; and Mr. Murray gives it from localities on 
Hudson's Bay. Its showy plumage, attracting attention, has 
caused the Indians to give it a special name. The Crees of the 
Saskatchawan call it “ Ousawoo-peeasees " (the Yellow Bird). 
Dendrceca maculosa. 
The Black-and-yellow Warbler rests on the authority of the 
‘ Fauna Bor.-Am.' as a bird of the Saskatchawan; for I did not 
obtain a specimen, but only saw what I took for the bird, and 
hailed it as an old acquaintance of Nova Scotia. It has been 
found on the Mackenzie by Mr. Bernard Ross. 
Dendrceca palmarum. 
A single specimen, from the Lower Saskatchawan, is mentioned 
in the f Fauna Bor.-Am.' under the name of Sylvicola petechia. 
Mr. R. Kennicott has supplied the Smithsonian Institution from 
Red River Settlement; and Mr. Ross notes it as rare at Great 
Slave Lake. 
Myiodioctes pusillus. 
Rare on the Mackenzie (Mr. Bernard Ross). 
Myiodioctes canadensis. 
A single specimen is recorded in the 1 Fauna Bor.-Am.,' taken 
to be of this species, from the Lower Saskatchawan. 
40. Setophaga ruticilla. 
Besides my specimen ( f Ibis,' vol. iv. p. 4) from the Saskat¬ 
chawan, this bird is noted in the ‘ Fauna Bor.-Am.,' and given 
by Mr. Bernard Ross as reaching the Arctic Circle, on the Mac¬ 
kenzie. 
Hirundo horreorum. 
The Barn Swallow, on the authority of the f Fauna Bor.-Am./ 
builds within the Arctic Circle in May, and leaves early in Au¬ 
gust. It is mentioned by Mr. Ross as rare at Great Slave Lake.
