the open prairie. It is a slight affair,—merely a shallow depres- 
sion in the ground, lined with a few dried grass stems. The eggs 
are four or five in number, measuring nearly an inch in length by 
about three-fifths in breadth ; they are very variable) in contour. 
The colour is well adapted to concealment in the gray-brown nest, 
being nearly the colour of the withered materials upon which 
they rest, thickly and uniformly dotted with light brown. The 
eggs and young birds, like those of other small species nesting 
on the ground in this region, often become the prey of the foxes, 
badgers and weasels, if not also of the gophers. (Cowes.) Num- 
bers of nests were obtained and examined in a wagon trip of 500 
miles in 1895 and all were of the same character. The nest was 
always a small hole in the ground lined with dried grass and con- 
tained from two to four eggs. The latter seemed to be the usual 
number. (Jacoun.)

4747. Dusky Horned Lark. 
Otocoris alpestris merrilli DwiGHT. 1890. 
Specimens of this form in breeding plumage have been examined 
from Ashcroft and Kamloops, B.C.; non-breeding from Chilli- 
wack. (Dwzght.) Observed only in the interior at favourable local- 
ities. A few pairs were found on a mountain near Ashcroft, B.C., 
in July and were doubtless breeding. (Szveator.) This form was 
found breeding at Spence’s Bridge and ten miles south of Kam- 
loops, B.C., by some alkali ponds in June, 1889, one specimen, a 
young male, was taken June 24th at Kamloops, B.C. (Spread- 
borough.) Taken at Chilliwack, B.C. (Byvooks.)
