362 Mr. P. L. Sclater on the Neotropical Pipits. 
under my eyes three skins from Lima {Nation), and two from 
Southern Peru^ Islay^ and Arequipa {Whitely), which belong 
to the recently described A. peruvianus of Mr. Nicholson. 
After examining them^ and considering the differential cha¬ 
racters pointed out by Mr. Nicholson, I do not find these 
characters hold when the whole series is examined. In one 
of my Lima skins the outer tail-feathers are quite as white 
as in Brazilian specimens; and there is every variety as 
regards the white edgings of the wing-coverts, taking the 
series as a whole, though this feature is most pronounced in 
the Peruvian birds, and least apparent in the Central-American 
specimens. I admit that the yellow tinge of the abdomen is 
not apparent in the so-called A. peruvianus ; but this is, in 
my opinion, not sufficient to found a species upon, and this 
tinge is likewise deficient in the Central-American skins. 
The length of the hind claw in my ten specimens of this 
species varies from O'50 to about 0*38 inch. 
If the three forms of this species shall be ultimately esta¬ 
blished as distinct, it would be better to reject the term rufus 
altogether as void for uncertainty, and to use lutescens for the 
Brazilian form, parvus for the Central-American, and peru¬ 
vianus for the Western bird.
