363 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 0*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 r'ufus 

 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.
