Mr. P. L. Sclater om the Neotropical Fip'its. 363 



(/. s. c.) has given us an excellent account of its habits in the 

 Argentine Republic^ and says it is the only Anthus known to 

 him there. I have an example obtained by him near Con- 

 chitaSj a series of four from Santiago , Chili [Landbeck) , 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 shafts 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 oi A. correndera. The specimen is certainly 

 rather more rufescent on the breast than any example of -^. 

 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.
