Squatarola helvetica, (Linn.) 
Severn House. 
This may be looked upon as only a northern state of our grey 
plover. My specimens are in full breeding plumage, and the 
ground colour of all the upper parts nearly white ; certainly 
appears to be influenced by climate. 
Strepsilas interpres, (Linn.) 
Hudson's Bay and Severn House. 
A citizen of the world. 
Grus Canadensis, (Temm.) 
Trout Lake Station. 
Botaurus lentiginosus (Montag.), (American Bittern). 
Severn House. 
Numenius Hudsonicus, (Lath.) 
Severn House. 
Tringa alpina, (Linn.) 
Severn House. 
Totaniis melanoleucus (Gmel.), (yociferus. Sab.) 
Severn House. 
The specimens received agree with Gmelin's description of the 
breeding plumage, but differ somewhat from those usually 
seen, which generally come farther from the south. 
Totanus flavipes^ (Vieill.) 
Severn House. 
Limosa fedoa^ (Linn.) 
Hudson's Bay. 
Limosa Hudsonica, (Lath.) 
Severn House. 
Phalaropus lobatus, (Ord.) 
Severn House. 
Anser hyperboreus (G-mel.), (Wavey ; Snowy Goose). 
Moose Factory and Severn House. 
Bernicla Canadensis (Linn.), (Cravat Goose ; Canada Goose). 
There are most probably more than one species confounded 
under the old name of Anas Canadensis of Linnaeus, founded on 
the figures of Brisson, Catesby|and Edwards, which all evidently 
refer to one species. Sir John Richardson mentions two Indian 
synonymes for it — viz., Neescah SbndMistehay-neescahjhesides 
that of Apisteeskeesh for Hutchin's goose, from whence we may, 
I think, legitimately infer that the Indians recognise two spe- 
cies at least, this being peculiarly a case where dependence 
may be placed on the observations of natives, the animals 
being one of the objects of their chase, and a knowledge of 
the habits and distinctions of different species being essential
