the Province of Buenos Ayres. 59 



and in considerable numbers. I shot some, to identify them, 

 on both occasions. 



5. Tanagra cyanoptera, Vieill. ; Nomencl. p. 14. 

 Observed in January and February 1877 in the riverain 



wood, but all that I have met with have been immature birds. 

 Iris wood-brown ; beak lead-colour ; feet pale slate. Feeds 

 on buds and berries. 



6. Saltator CiERULESCENs, ViciU. ; Nomencl. p. 26. 



I found this bird pretty common near Baradero in April 

 1876, on low scrubby ground in the neighbourhood of water. 

 Stomach of one shot contained buds. Beak very dark horn- 

 colour ; legs not so dark, soles pale flesh-colour ; iris dark 

 brown. I have not met with this bird near Buenos Ayres. 



7. Icterus pyrrhopterus, Vieill. ; Nomencl. p. 37. 

 Common at Baradero in April 1876, and seen at Alvear in 



September. 



8. Xanthosomus flavus (Gm.) ; Nomencl. p. 37. 



Rare. I shot one specimen on the 9th September 1876 at 

 Alvear. Iris wood-brown ; beak and legs dark horn-colour. 



9. PsEUDOLEisTES viRESCENs (Vieill.); Ibis, 1877, p. 175. 

 Nests in November, and makes a neat structure of hair 



and a little grass, lined with feathers, and placed in reed-beds. 

 It is usually situated about four feet above the water, and 

 supported on all sides by reeds. The eggs have a white 

 ground-colour, minutely speckled, chiefly at the larger end, 

 with light and dark purple spots, some inclining to rufous. 

 I have observed this species in this district in April, and also 

 from September to December. 



10. Fldvicola albiventris (Spix) ; Nomencl. p. 43. 



A summer visitor, and pretty common then in the riverain 

 wood. Like the other Tseniopterinse, it sometimes remains 

 motionless on a twig for some time, and suddenly makes a 

 dart at some passing insect. It is fond of perching near the 

 ground. Iris rufous brown ; beak, legs, and feet black, soles 

 of latter grey.
