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 1 have met with have been immature birds. 
Iris wood-brown; beak lead-colour; feet pale slate. Feeds 
on buds and berries. 
6. Saltator CiERULEScENs, Vieill.; Nomencl. p. 26. 
I found this bird pretty common near Baradero in April 
1876, oh 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. 
Bare. 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. Fluvicola albiventris (Spix) ; Nomencl. p. 43. 
A summer visitor, and pretty common then in the riverain 
wood. Like the other Tseniopterinae, 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.
