1882. ] FROM THE ARGENTINE REPUBLIC. 605 
females, which I shot on the edge of a lagoon. In Flores a very 
wild specimen (the only one seen, in fact) was secured in the batiado 
or low swampy ground ; it continued flying along and settling on 
the ground, but seemed disinclined to make for any shrubs, although 
some were near at hand. 
The nest is found close to the edge of the lagoon, about half a 
yard above the water, and is built pendent from two or three rushes 
united ; covered at the top, with the exception of a small circular 
entrance 13 inch in diameter, placed at one side, and at times 
another small entrance near the bottom; it is constructed of roots 
of grass and rushes tightly cemented together, and beautifully lined 
with down. The external measurements of the nest are 4 inches in 
height and 3 in diameter. 
The egg, which is of a deep bluish-green and spotless, has a 
peculiar squat form, the upper part truly hemispherical, the lower 
spheroidal. Three eggs in a clutch. 
Meas.: axis 19 millim., diam. 163 millim. 
72. PLATYRHYNCHUS MYSTACEUS (Vieill.). 
. San Javier, Misiones, Arg. Rep., June 7, 1881. 
This bird was shot in the woods, and was the only specimen 
obtained. 
73. EvscartuMus Guarts (Temm.). 
3. Santo Tomé, Corrientes, Arg. Rep., May 11, 1881. 
A bird that is found in the thickest parts of hedges, on the out- 
skirts of the town of Oran, and has a pretty warble. It is very 
difficult to see, and appears rather uncommon. It was likewise 
observed in Misiones, and with the same habits. 
74. EUSCARTHMUS MARGARITACEIVENTER (d’Orb. et Lafr.). 
do. Oran, Salta, Arg. Rep., Nov. 15, 1880. 
Abundant about the hedgerows in the vicinity of Oran. 
75. CULICIVORA STENURA, Sw. 
3. Itapua, Misiones, Arg. Rep., July 18, 1881. 
This pretty little bird is the only one of its species I have seen 
anywhere in the Republic. I shot it on marshy land near the 
river Saima, some three miles off Itapua. As I was working my 
way through the marsh I heard a tiny creaking chirp, which I took 
to proceed from a cricket, but afterwards from a bird, although 
I could not see one ; but on beating the grass, the chirp meanwhile 
receding, something flew up as it were a locust. I followed it with 
my eye, and marked it settle upon a small reed, where I shot it.
