1882.] FROM THE ARGENTINE REPUBLIC. 601 
This pretty song-bird is exceedingly common around the houses 
in the suburbs of Buenos Aires. 
The nest, when located in holes in the houses, is built of straw 
and twigs, but when in trees is usually lined with horsehair. The 
breeding-season extends from early spring to autumn; and the 
eges, rather sharply pointed, are of a light green ground, mottled 
with brown spots ; and the clutch consists of four. 
Meas. : axis 19 millim., diam. 14 millim. 
[I have not seen Mr. White’s specimens; but they are probably 
S. pelzelni, mihi, Ibis, 1872, p. 42, if the species are distinct, as I 
believe is the case.—P. L. S. |

The birds are common all over the Republic. It is usual for 
them to lay in the nests of other birds, such as Troglodytes furvus ; 
indeed I have never known these lazy architects take the trouble to 
construct their own dwellings. 
The number of eggs varies in different nests, as likewise their 
coloration. All, however, have a white ground; but some are dotted 
with large rufous-brown spots, whilst others are entirely devoid of 
them; but the typical shell is sprinkled over thickly with minute 
reddish-brown spots on a white ground. 
Meas.: axis 24 millim., diam. 19 millim.

Iris brown. 
Rather common round the hedges and high trees by the side of 
alfalfa-fields in the neighbourhood of Andalgala, but by no means 
rare likewise in the province of Buenos Aires. In the spring of 
1882 I obtained near Salto, Buenos Aires, its eggs, and found them 
laid in an old and large nest built of sticks by Anumbius acuticau- 
datus, high up in a Eucalyptus tree. The old birds kept near the 
nest, and, the moment any one approached, came close up to and 
around him, sereeching. Four eggs in a clutch; the shell rather 
elongated, with pale green ground, streaked and spotted with dark 
sepia, thicker around the blunt end. 
Meas.: axis 22 millim., diam. 16 millim. 
52. AGELZUS PH@NtICcEvUs (Linn.). 
3. Adrogué, Buenos Aires, Arg. Rep., Jan. 28, 1881. 
Iris dark. 
Of these birds I obtained two or three in a maize-field. 
[This specimen requires examination. I have never seen A. phee- 
niceus from anywhere so far south.—P. L. S. ]
