in composition and size— are very much alike; both are rather 
loosely put together, but there is quite a distinguishing difference 
in the eggs; those of M. varia are actually the largest, and more 
globular in form, and the ground colour more of a chalky whiteness, 
and the spotting more of a brownish hue; with a general tendency 
to form a wreath about the larger end, and be distributed over the 
surface, even to the smaller point; the eggs of the Canadian warbler 
have a clear white hue, with a beautiful rosy blush, and the colour- 
ing which clouds the whole of the larger end of each egg, has more 
of an orange tinge than either reddish or brown, the dotting on the 
surface is more separated, and the approach to the smaller point 
more devoid of dotting than are those M. varia, but in all the speci- 
mens the variations are so numerous that it is difficult to describe 
them; this species is very local in its distribution, being generally 
found to frequent the borders of swampy woodlands, having much 
the same habitat as the water-thrush and M. varia, but here it is 
more abundant than either of the other species, and seems more 
disposed to explore the underwood of the higher hardwood lands 
and nests on more level ground; altogether about a score of the nests 
of this species have come under my observation in my woodland 
rambles in the vicinity in the past twenty years ; and, as in the 
case of the water-thrush, black-and-white warblers, and severa] 
other species, several of these nests were in cavities previously pre- 
pared forthem. (W.L. Kells.)

A poor skin was shown Mr. A. Halkett at Port Burwell by the 
factor of the station showing that this species occasionally reaches 
the north of Labrador. (Rev. G. Exfrig.) A specimen was taken at 
Rupert House, September 3rd, 1860, by Mr. James McKenzie. 
(Packard.) Common all along Moose river to James bay. On June 
gth, found a nest with two eggs in a white birch about four feet from 
the ground. Nest composed of fine bark lined with the down of 
some plant. (Spreadborough.) A summer migrant but rare in the 
north of Newfoundland. (Reeks.) An abundant summer resident
