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 banado 

 or low swampy ground ; it continued flying along and settling on 

 the ground, hut 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 1| 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.

72. Platyrhynchus mystaceus (Vieill.). 



2 . San Javier, Misiones, Arg. Rep., June 7, 1881. 

 This bird was shot in the woods, and was the only specimen 

 obtained. 



73. Euscarthmus GULARis(Temm.). 



cJ. Santo Tome, 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.). 



cJ. Oran, Salta, Arg. Rep., Nov. 15, 1880. 

 Abundant about the hedgerows in the vicinity of Oran. 



75. CULICIVORA stenura, Sw. 



c? . 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 Saimsi, 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 

 niy eye, and marked it settle upon a small reed, where I shot it.
