it seems to meet the Siberian form. It is said to breed in northern 
British Columbia, and the specimens taken, although not referable, 
according to Mr. S. N. Rhoads, to C. julvus, are darker underneath 
than eastern specimens. Brooks saw it, in the Cariboo district, 
however, only during the fall migration. 
BREEDING NoOTES.—The breeding quarters of this well known bird 
are the Barren Grounds and the coasts and islands of the Arctic sea. 
It hatches early in June, and retires southward in August. (Rvchard- 
son.) This beautiful species is very numerous in the Barren Grounds 
from the outskirts of the forest to the shores of the Polar sea. The 
nests were found to be precisely similar to those of C. squatarola. 
They were also as difficult to detect, and for the same reason, a 
harmonizing resemblance of the egg markings to the surrounding 
soil and a timeous departure of the female bird from her nest. I 
find 170 nests recorded in my notes. Except when there was reason 
to believe that the full number had not been deposited, four eggs 
were always met with. In one case there were five and in another 
only one. (Macfarlane.) Breeds commonly on Herschell island, 
from where I received a number of sets of eggs. It makes a hollow 
jn the moss on the slopes of elevated and rising ground. (Ravzne.\ 
This species arrives on the shores of Norton sound, Alaska, about 
the end of May. They.soon pair and disperse, so that a few days 
after the main arrival, their nests may be looked for. The nests 
are generally in small depressions, which may be found among the 
moss and dried grass of a small knoll, and at times a slight structure 
is made of dried grass. The grass, and perhaps, a few dead leaves 
of the dwarf willow are arranged in a circular, saucer-shaped form, 
about four or five inches across, and contain four eggs, which have 
a pale, yellowish ground colour, with very dark well-defined umber- 
brown spots, scattered rather profusely over the shell, especially 
about the larger end. (Nelson.) The golden plover arrives at 
Point Barrow about the end of May. It was nesting before June 
2oth, both seasons I was at Point Barrow, though I was unable to 
find its nest before the 22nd. The nest is exceedingly hard to find, 
although it is not concealed at all, but is simply a depression in the 
bare black clayey tundra, lined with a little dried moss. The only 
vegetation on this part of the tundra is white and grayish moss, 
which harmonize so extraordinarily with the peculiar blotching of 
the eggs, that it is almost impossible to see them unless one knows
