ANTHUS. V57 
Total length, 4.35; wing, 2.26; tail, 1.94; difference between Ist and 6th 
quills, .32; length of bill from forehead, .51, from nostril, .35, along gape, 
.61; tarsus, -77; middle toe and claw, .66; claw alone, .20; hind toe and 
claw, .70; claw alone, .40 
This species is much like Neocorys spraguez in appearance, though 
much smaller (an inch and a half shorter), and with a greenish-yellow 
gloss on the under parts, wanting in the former. The coloration is 
otherwise very similar. The wings are shorter and not so much 
pointed, the 5th quill being half way between the 4th and 6th, instead 
of being two-fifths of the total distance from the 6th, and three-fifths 
from the 4th. The hind toe and claw are perhaps not quite as long, 
but still about equal to the tarsus. Whatever, therefore, be the 
validity of the genus Neocorys, the N. spraguei appears to be the 
nearest relative of the present species, agreeing with it in shorter 
tail and longer legs compared with Anthus, but differing from both 
in the shorter, more rounded wings. 
Iam by no means certain of the correctness of identification of 
the specimen. No South American birds are, perhaps, in a greater 
state of confusion than the Titlarks; and in the absence of accurate 
indications of the proportions of the quills, etc., so necessary in de- 
fining species which vary so little in color, it is exceedingly difficult 
to come to an accurate conclusion on the subject. It is not at all 
improbable that the present species may prove to be undescribed, as 
it is its diminutive size, rather than anything else, that has caused 
its reference to the Alauda rufa of Gmelin.

Although there are no members of the present section known with 
certainty to belong to North or Middle America, I describe the two 
South American species before me as a contribution to the history 
of the genus.
