everywhere at Fernie and Elko, B.C., in 1904, and common every- 
where at Midway, in 1905; common in the same year on mountains 
between the Skagit river and Chilliwack lake. (Spreadborough.) 
The junco breeding in the plateau region between the Coast range 
and the Rockies and migrating south in winter, is evidently separable 
from the coast form. Specimens referred here were collected at 
Ashcroft, in June and July, 1889; taken also by Mr. Macfarlane at 
Stewart lake with its nests and five eggs. (Streator.) Abundant 
at Lake Okanagan, B.C., in winter. (Brooks.) A female was taken 
at Glacier in the White pass, June 7th, 1899, and another at White 
Pass City, June 9th; others were taken and heard next day, both at 
Glacier and White Pass City. (Bzshop.) 
BREEDING NoTEs.—On May 3I!st, 1902, found two nests near 
Trail, B.C.; one with four eggs, the other with two; incubation was 
far advanced. Nests constructed of weeds and grass, lined with 
hair. Both nests were in a bank overhung with grass; another was 
found on May 25th in the bank of an old prospect hole with four 
fresh eggs. Found a nest in a clump of bunch grass at Midway, 
B.C., May 3, 1905; it was made of grass and lined with fine hair; 
June 22, saw a nest with four eggs in a bank, under a small bush at 
the head of Whipsaw creek at an altitude of 6,800 feet. (Spread-

568. Mearns Junco. 
Junco mearnst RIDGWAY. 1897. 
This form accompanies hyemalis in the migration at Carberry, 
Manitoba. (E. T. Seton.) Mr. E. T. Seton refers this bird to 
shufeldti, but having taken mearnst at Medicine Hat in 1894, and 
found them breeding in June on the east end of the Cypress hills, 
about 100 miles southeast of that point, we place his reference under 
that species. (Macoun.) I secured a female and two young in the 
Cypress hills, Sask., and a male and one young several miles away 
on the following day; no others noted. (Bishop.) Quite common 
at Banff, Rocky mountains, in the summer of 1891; nests were taken 
on Tunnel mountain. They were always placed on the ground 
beneath a bush or on a slope. Breeds twice in a season at Banff.
