Iris sepia. 



Rather common in the province of Buenos Aires, where it is found 

 plentifully in swampy ground. The cone-like nest is constructed 

 of grass and rusii, lined with fine grass, and is placed about a foot 

 above the water, between two or three rushes united together. The 

 egg, rather elongated and pointed, has a bluish ground with black 

 markings around the blunt end. It measures, axis 22 niillim., diam. 

 1/ millim.

 cJ. Salta, Arg. Rep., Oct. 23, 1880. 



2 . Salto, Buenos Aires, Arg. Rep., Oct. 10, 1881. 



Iris sepia. 



These birds, usually met with in marshy ground in October, fre- 

 quent the alfalfares (lucerne-fields), evidently for nesting-purposes. 

 The male has a very pretty song, which is usually uttered whilst 

 poised on the wing ; and, after the strain is finished, descending 

 to the ground, it perches on some long grass-stalk. 



57. Pseudoleistes virescens (Yieill.). 



c? . Punta Lara, Buenos Aires, Arg. Rep., Feb. 21, 1881. 



Iris dark brown. 



Found abundantly in this district, flying in flocks of about 

 twenty. They settle in the marshy land, and, if disturbed, take to 

 the topmost twigs of the belt of tala trees that here line the shore 

 of the river. 



58. Cyanocorax pileatus (Temm.). 



(S . Campo Colorado, Oran, Salta, Arg. Rep., Nov. 4, 1880. 



Iris yellow. 



This Blue Jay is very common about the woods at Campo Colo- 

 rado, and, besides being remarkably tame and inquisitive, has a great 

 variety of peculiar grating metallic notes. Ou the sierras of Totoral 

 I likewise met with it ; and it is found as far south as Tucunian and 

 Catamarca.
