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 very 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. 

 co'^rendera 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. 



5. Anthus furcatus. 



Antlius furcatus, Lafr. et D'Orb. Syn. Av. p. 27; D'Orb. 

 Voy. Ois. p. 227; Darwin, Zool. Beagle, iii. p. 85 (La Plata). 



Anthus brevirostris, Tacz. P. Z. S. 1874, p. 507 (Peru). 



I have compared one of Mr. Taczanowski's 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. 

 Whether, 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 thes6 

 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
