Argentine Republic^ and not previously met with there. The 

 accompanying specimens have been examined by Sclater, 

 who appends a few remarks. — Edd.] 



1. MiMUs PATACHONicus (Arg. Orn. i. p. 7). 



This Moclcing-bird arrives here in April, departing in 

 spring. It lives singly or in pairs amongst the bushes, and 

 occasionally utters a few irregular notes. 



[A young female of this species (Sta. Elena, 3. v. 93), 

 which I should not have expected to occur so far north, 

 ''Iris olive-green; legs and bill black." — P. L. S.] 



2. Progne furcata (Arg. Orn. i. p. 24). 



I have observed a pair of adults of this species all through 

 the summer, and on January 21st I found them accompanied 

 by two immature birds, one of which I shot. I can only 

 conclude that they nested in an old ruined mud-house, 

 which is never visited by anyone. It contains many holes, 

 which are occupied by various birds in the breeding-season. 



It seems very far north for this species to breed, though 

 many pass here on migration. 



3. ViREosYLViA CHivr {Arg. Orn. i. p. 22) . 



A shy summer visitor, frequenting the plantations, where 

 it passes from one tree to another searching for insects, 

 occasionally making a short flight after these on the wing. 

 Its note is a faint hiss twice repeated. 



[Mr. Holland sends a skin of this species, which he was 

 inclined to refer to the Tyrants. '' Sta. Elena, 12. xi. 93 : 

 legs blue ; iris hazel ; bill dark brown, beneath bluish." — 

 P. L. S.] 



4. DoNACospizA ALBiFRONs (Arg. Orn. i. p. 49). 



Eairly common throughout the winter in small companies, 

 which frequent the dried weeds and montes. This specimen 

 was the brightest in a flock. 



[The specimen sent by Mr. Holland ( ? , 29. vi. 93), and 

 supposed by him to be a Poospiza, is a young bird of the 

 allied form, Donacosjnza albifrons. — P. L. S.]
