Mr. P. L. Sclater on the Neotropical Pipits. 
{1. s. c.) has given us an excellent .account of its habits in the 
Argentine Repuhlic_, and says it is the only Anthus known to 
him there. I have an example obtained by him near Con- 
chitas^ a series of four from Santiago, Chili {LandhecP), and 
a single skin from the Falkland Islands^ besides an odd 
Chilian specimen. In these birds^ and in others now before 
me_, there is considerable variation in the length of the hind 
claw; but as a general rule the hind claw is long and rather 
straight, measuring in the longest-clawed specimens 0*7 inch 
in a straight line from the base to the tip, but in others not 
quite reaching 0*5. 
As a general rule, the second anterior rectrix in A. corren- 
dera is white at its tip; and this white colour is continued in 
a narrow line along the inside of the shaft, nearly down to the 
base of the feather, the shaft itself being white down quite to 
the base. But in a large series there will be found excep¬ 
tions to this rule. In some cases the white line extends only 
halfway down the feather; and in one of my specimens 
($ adult, ex Chili, Landbeck) it extends only about a third 
down on one side, and two thirds on the other, which proves 
that this is a variable character. 
Mr. Taczanowski has most kindly sent me for examination 
the type of his Anthus calcaratus. My impression is that this is 
a freshly-moulted example of the present species. The outer 
rectrix is wholly white, with a black patch on the inner web 
at the base; and the second rectrix is coloured quite after 
the usual pattern of A. correndera. The specimen is certainly 
rather more rufescent on the breast than any example of A. 
correndera I have seen; but I think this may be due to its 
recent moult, as is the case in other Pipits. In the length of 
the hind claw it is exceeded by some of Mr. Hudson^s Buenos- 
Ayres specimens. The fifth primary is about equal to the 
first in length, the sixth being rather more than 0*2 inch 
shorter. 
I have also carefully examined the two skins (21,035 and 
26,362 of the Smithsonian Institution) described by Prof. 
Baird in his ‘ Review,^ p. 158, but not named, and have come 
to the conclusion that they must be referred to this species.
