362 GEOLOGICAL SURVEY OF CANADA. 
Three sets of eggs. One of three taken at Great Whale River, 
James Bay, June, 1899, by Mr. A. P. Low, one of three taken on an 
island in James Bay, June 18th, 1896. by Mr. Spreadborough, and 
one of four taken at Cape Prince of Wales, Hudson Strait, June, 
1885, by Mr. F. F. Payne. 
474¢. Pallid Horned Lark. 
Otocoris alpestris leucolema (COUES) STEJN. 1882. 
Alaska and western British America, southward in winter into 
the United States. A few breeding birds from the Saskatchewan 
and Great Slave Lake region, though tinged with yellow on the 
chin, are, on account of size and colours somewhat paler than @- 
pestris referable to leucolema ; so, too, are large dark birds with 
white eyebrows and pale yellow chins found in winter in the 
upper Mississippi valley, coming as they doubtless do from an 
intermediate region between Hudson’s Bay and Alaska. Breeding 
birds of these two races are few and limited mainly to those taken 
on Government expeditions ; consequently I do not draw the 
lines on the map as closely together as with some of the other 
races better defined. Two young, in first plumage, taken on 
the Arctic coast, east of the Anderson River, may be referred to 
this race. While they are not as black and white as might be 
expected in Alaskan birds, they lack the general yellowishness of 
young a@/pestris from Newfoundland, In winter dewcolema is found 
as far south as the middle of the western United States, mostly 
east of the Sierra Nevada mountains, Northwest coast speci- 
mens indicate that a small-sized /ewcolema may breed in the 
mountains not far north of the United States boundary, though 
such birds may generally be referred to merri/. A male in autumn 
plumage, taken August 26th at Chief Mt. Lake, on our northern 
boundary, Long.114°,W. suggests the possibility of this form breed- 
ing also on the mountains at that point, or not far to the north. 
It is not reported from Pt. Barrow, is rare at St. Michael, Alaska, 
and is probably an interior race. Breeding birds have been ex- 
aminedifrom Fort Yukon and St. Michael, Alaska; Arctic Coast 
east of Fort Anderson, also Horton Riverand Franklin Bay; from 
Fort Reliance, Fort Resolution and Big Island, Great Slave Lake; 
also from Saskatchewan region. Non-breeding from Chilliwack, 
B.C. (Dwight.) This very handsome lark arrives in the North- 
west Territories along with the Lapland bunting, with which it
