130 Capt. Blakiston on the Birds of the 
obtained specimens and eggs on the Saskatchawan (‘ Ibis/ vol. iv. 
P- 8). 
JE. montana, having been obtained on the Upper Missouri, 
will probably be found in the western parts of British territory. 
jUgialitis 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. Boss, 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 e Fauna Bor.-Am.;' but I now observe that it has 
been found by Mr. Boss 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. Boss has given it as a rare bird on the Mackenzie. 
BeCURVIROSTRA 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. Boss 
considers it rare on the Mackenzie. The White Avocet of 
Cassin is considered only an accidental variety of this species. 
Phalaropus wilsonii. 
This bird is given in the f 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. Boss notes it as a rare bird 
on the Mackenzie.
