retained the name^ although subsequent to D^Orhigny^s, so as 
to avoid the confusion of this species with Anthus rufescens 
of Temminck.

It is of course quite impossible to say positively what the 
Chii of Azara, and consequently the Anthus chii of 
Vieillot, may have been. All we can decide from Azara'^s 
description is that the Chii (thus designated by him from 
its note when it descends to the ground from the air) is a second 
species of Paraguayan smaller than the^^^Correndera'’^*. 
By many authors A. chii has been considered to be the same as 
the next species. But the specimen which I received some 
years ago, in exchange from the Berlin Museum, under this 
name, and which is consequently, at all events, the A. chiioi 
Lichtenstein, is not identical with the little A. rufus, but is 
decidedly larger and distinct. 
Anthus chii, then, if this be its correct name, is a bird much ^ 
resembling A. bogotensis, but decidedly smaller in size. The 
under surface is nearly uniform pale fulvous, paler on the 
throat and belly, but not passing into white or yellowish white 
on the latter part as in rufus. 
Besides the specimen received from Berlin, as above men¬ 
tioned, which was collected by Sello in Southern Brazil or ! 
Uruguay, I have seen but two examples of this species, both 
bearing Natterer’s number 463. Of one of them in my own 
collection the exact locality is not marked; the other, which 
Hr. V. Pelzeln has kindly lent me, is from Curytiba. 
This is consequently the Anthus rufus, Gmel.,^^ of Pel¬ 
zeln, but not the A. rufus commonly so called. Natterer met 
* Lengtli 4f, instead of Spanish inches.
