the labels. This is simply another proof of the difficulty and danger 
of attempting to identify specimens of Otocoris from new localities! 
As I remember, Mr. Norton’s female was rather small and unusually 
grayish; but your good series leaves no room for doubt.” 
Of the Bowdoin college specimen he writes (February 4, 1907): 
“Tt is certainly only a specimen of alpestris, probably somewhat 
aberrant.” 
In this connection we wish to speak of the recent extension of the 
breeding range of praticola to the east. ‘This was a subject about 
which one of us wrote in “‘The birds of Essex County” (Townsend 
1905, p. 235) and the Auk (vol. 21, 1904, p.81). In the Auk (vol. 23, 
1906, p. 225) Mr. Norton controverted this view basing his argument 
primarily on what he believed to be evidence of the existence of this 
form even in Audubon’s time on the southern Labrador coast as well 
as its occurrence there today. As we have just shown, Mr. Norton 
was in error as regards this. He also refers to Maynard’s record for 
eastern Massachusetts in July, 1869. A single case is of course of 
trifling value and when we consider that the numerous ornithologists 
in the well studied part of eastern Massachusetts have only within 
recent years found this bird breeding, it seems probable that some 
recent change in its range has occurred. ‘The evidence in New Hamp- 
shire and Vermont is also strongly suggestive. 
We observed the flight song of the Horned Lark at various places 
along the coast, and made an especial study of it at Great Caribou 
Island, Battle Harbor. The bird suddenly mounts high into the 
air, going up silently in irregular circles, at times climbing nearly 
vertically, to such a height that he appears but a little speck in the 
sky, several hundred feet up. Arrived at this eminence he spreads 
his wings and soars, emitting meanwhile his song, such as it is — one 
or two preliminary notes and then a series of squeaks and high notes 
with a bit of a fine trill. The whole has a jingling metallic sound 
like distant sleigh bells, although the squeaks remind one strongly of 
an old gate. The whole effect, however, is not unpleasant,— even 
melodious. Having finished one bar of his song, he flaps his wings 
a few times, closes them and sails again, repeating the song. One 
bird repeated his song twenty-four times and remained in the air one 
and a half minutes; another remained in the air three minutes, during 
which he repeated his song thirty-two times. During all this time 
the bird is flying in curves or irregular circles, sometimes in straight
