Interior of British North America. 63 



39, Dendr(eca 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 

 Dr. 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 '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 * Fauna Bor.-Am.,' taken 

 to be of this species, from the Lower Saskatchawan. 



40. Setophaga ruticilla. 



Besides my specimen {' 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 ' 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.
