in the Chuput Valley , Patagonia .

Sycalis luteiventris. 
Common, usually in flocks. Its nest is of grass, lined 
with horsehair, and is placed in a tuft of grass or rushes close 
to the ground. The eggs are four in number. Very com¬ 
mon at Ninfas Point. 
ZoNOTRICHIA CANICAPILLA*, Gould. 
Abundant, both in the valley and on the hills, and often 
to be seen hopping familiarly about the colonists* cottages. 
It nests amongst coarse grass or brushwood, making an un¬ 
pretending structure of the former material, the finer fibres 
being placed towards the interior. It lays four eggs, mea¬ 
suring *8 by *6 of an inch, of a pale green colour, thickly 
striated with light reddish brown spots, running into each 
other, and most numerous at the larger end. The eggs of 
the Chuput species differ from those I have from here of Z. 
pileata in the character of the markings, which are of a 
lighter colour and not so distinct, being more blotchy than 
in Buenos-Ayres examples. The nests are of precisely similar 
character. 
Agel^eus thilius. 
Very common throughout the valley and in every patch of 
rushy ground. Though I did not discover a nest, birds were 
undoubtedly breeding in the neighbourhood. 
Sturnella militaris. 
One of the commonest birds in the valley, not being seen 
on the hills. On the 4th November I took a nest from a 
tuft of Pampas grass close to the river-bank, containing two 
eggs. It occurred in some numbers at Ninfas point. 
Molothrus bonariensis. 
Not uncommon in the valley, frequenting willow-beds and 
clumps of brushwood. 
* [Mr. Durnford sends a single specimen of this species, which we 
have hitherto supposed to have been based upon the young of Z. pileata. 
We now see that it is fully entitled to specific rank$ see Sclater’s remarks, 
infrh, p. 46, where a figure of it is given, taken from Mr. Darn for Is spe¬ 
cimen.— Ed.]
