594 MR. E. W. WHITE ON BIRDS [June 20, 
This bird is exceedingly abundant in the province of Buenos 
Aires, but it is also met with nearly all over the Republic. Builds 
a nest of twigs and dry grass, lined usually with horsehair, in holes 
in the walls of barns and outhouses. I have not unfrequently 
found the eggs of this bird in old nests of Furnarius rufus, and 
sometimes even in the nest of Zonotrichia pileata, under a thistle 
in the campo. 
The egg is of a pinkish ground, thickly sprinkled with minute 
rufous spots, which are concentrated in a crown around the blunt 
end. 
Measurements: axis 19 millim., diam. 14 millim.

Tris dark. ; 
This bird is abundant at this season of the year in low-lying 
swampy pastures, where the grass is high. Upon being disturbed 
they start up high into the air, very much like an English lark, 
singing all the while very prettily, and remain poised on the wing. 
On the approach of a foot-passenger they crouch close to the 
ground, allowing the foot almost to tread upon them; and as they 
are of its exact colour, they are difficult to see. This habit leads 
the observant country urchins to compass the destruction of these 
poor birds, which they do by breaking off a piece of fencing wire, 
about a yard and a half long, turning it up at the ends, seizing it by 
one extremity, whirling it round their heads, all the while approaching 
the feathered songsters, and then suddenly launching the chain shot, 
which rarely misses its errand.

Tris dark. 
In the sierras of Totoral I met with this bird, usually in the thick 
parts of the woods ; yet it was not very common. It has a nice lively 
chirp and is very quick in its movements. But in Misiones I found 
it very abundant in the dense woods.

Tris sepia. 
I shot this bird out in the open country, where it was hopping 
about in the thickest part of some low bushes near a running stream.

This bird is not at all uncommon in the woods of Misiones.
