304 GEOLOGICAL SURVEY OF CANADA. 
I found three nests containing eggs of this species. The 
nests were built in hollows in the ground, the brim of the nest 
flush with the surrounding soil. Each nest contained four eggs 
similar to those of the prairie horned lark. I secured two birds 
which are easily distinguished from the prairie horned lark by 
their paler form. (W. Raine.) I believe this form was arenicola, 
as I have found it breeding everywhere on the prairie. ((/acoun.) 
BREEDING Notes.—Nine nests of this lark were received at 
Fort Anderson—a few of them from the Esquimaux, and the 
others were collected by us in “the barrens” and on the coast of 
Franklin Bay. The nest was usually composed of fine hay neatly 
disposed and lined with deer hair. Several of the parent birds 
were secured by snares placed thereon. (MMJacfarlane.)

Otocoris alpestris praticola HENSH. 1884. 
This bird is a miniature /ewcolema, somewhat darker and witha 
pale yellow chin which is seldom bright, and is often white. 
Autumn birds seem to show more linear spots on the breast than 
do the other forms, but this is not a constant feature. It seems 
to have gradually extended its range eastward as the woods have 
disappeared, and we can see why it should be nearer to /eucolema 
than to alpestris. However, as we go westward, we find a direct 
gradation into avenicola and this race passes directly into /euco- 
lema. Now Jleucolema passes into alpestris, and somewhere in 
the Saskatchewan or Winnipeg regions we shall find, I venture to 
say, breeding birds that might be referred to any one of these four 
forms. Breeding birds have been examined from Toronto, Peel 
Co., and Rat Portage, Ont.; Carberry, Man. (Dzwigit.) 
A specimen of this form was shot at Chateau Bay, southern 
Labrador, on July 14th, 1891, which was possibly a straggler, but 
may indicate that this form is a regular summer visitant to all 
eastern Quebec and the Straits of Belle Isle. (Vorton.) A com-
