364 Mr. P. L. Sclater on the Neotropical Pipits. 
I have no doubt that Prof.-Baird is correct in supposing that 
the latter is of the same origin as the former (Uruguay), and 
did not come from any part of North America. These two 
specimens are peculiar in having the breast-spots nearly 
lineiform, and not expanded into arrow-heads. This is espe¬ 
cially the case in no. 21,035. But I can verj^ nearly match 
this in other skins. The hind claw in both specimens is 
rather short; and there is but a slight extension of the white 
line downwards in the second external rectrix. As regards 
the conformation of the primaries, upon which Prof. Baird 
lays so much stress, I find on examining a large series of A. 
correndera much variation in this part of the structure. The 
fifth primary is generally rather shorter than the first, and the 
second, third, and fourth nearly equal and longest. But in 
some skins the first primary fully equals, and even exceeds, 
the next three in length; and the fifth is then definitely shorter 
than the first four.

! I have compared one of Mr. TaczanowskPs specimens of his 
Anthus brevirostris with the type of A. furcatus at Paris, and 
believe I may say that they belong to the same species. 
Mhether, however, it will be ultimately possible to keep this 
form distinct from A. correndera I am not quite so certain. 
One of Mr. Hudson’s skins from Conchitas in my collection 
and two others in the Smithsonian series, all marked Ca- 
chila ” by Mr. Hudson, and not distinguished by him from 
A. correndera^ certainly cannot be separated from A. fur¬ 
catus. 
The characters of this species (if, as I say, it is to be kept 
distinct) are the smaller bill, short and more curved hind 
claw, less spotted under surface, and different markings of the 
second outer rectrix. There are slight variations in all these 
points, which render it difficult, to say the least of it, to decide 
in every case to which of the two species a particular specimen
