obtained specimens and eggs on the Saskatcliawan {' Ibis/ vol. iv. 

 p. 8). 



jE. montnna, having been obtained on the Upper Missouri, 

 will probably be found in the western parts of British territory. 



^GIALITIS SEMIPALMATA. 



In the 'Fauna Bor.-Am/ a specimen is recorded from near 

 York Factory; and Mr. Murray mentions it from Severn 

 House, also on the coast of Hudson's Bay, and between there 

 and Lake Winipeg. Mr. Ross, moreover, notes it as common 

 on the Mackenzie. 



Squatarola helvetica. 



I fancied this bird was confined to Hudson's Bay, whence I have 

 received a specimen, as well as Mr, Murray ; and one is recorded 

 thence in the ' Fauna Bor.-Am. ;' but I now observe that it has 

 been found by Mr. Ross on the Mackenzie, but it is rare. 



Strepsilas interpres. 



I have received several specimens of the Turnstone from York 

 Factory, where I observed it myself in August ; and it is recorded 

 by Mr. Murray, and in the ' Fauna Bor.-Am. ' from Hudson's 

 Bay. Mr. Ross has given it as a rare bird on the Mackenzie. 



ReCURVIROSTRA AMERICANA. 



The American Avocet is given in the * Fauna Bor.-Am.' as from 

 the Saskatchawan Plains, where, on the shores of the shallow 

 lakes, it feeds on insects and small fresh-water Crustacea. I 

 shot the bird in such localities near Fort Carlton. Mr. Ross 

 considers it rare on the Mackenzie. The White Avocet of 

 Cassin is considered only au accidental variety of this species. 



Phalaropus wilsonii. 



This bird is given in the 'Fauna Bor.-Am.' as breeding on 

 the Saskatchawan, but not observed near Hudson's Bay. 



Phalaropus hyperboreus. 



The same authority mentions this species as breeding on 

 the Arctic coasts, and resorting to Hudson's Bay in autumn, 

 whence I have received specimens. An individual is recorded 

 from Great Bear Lake ; but Mr. Ross notes it as a rare bird 

 on the Mackenzie.
