from the Argentine Republic. 133 



the following species, which have been likewise identified by 

 Mr. Sclater and Mr. Salvin. 



1. Progne chalybea. 



This Swallow is very common. 



2. Cyanocorax pileatus. 



This bird is common in the woods ; and one generally knows 

 its whereabouts by its noise. It is not easy to procure good 

 specimens, as the feathers are fine and loose, and the bright 

 yellow breast and belly show the smallest stain of blood. 



3. Tyrannus melancholicus. 



Common. The species, however, most frequently met with 

 is a larger bird with a brown back, yellow breast, and a black 

 stripe through the eye, about as large as a Thrush • it may 

 generally be seen near water, sitting on an overhanging bough 

 and uttering at intervals a loud shrill cry. 



4. DRYMORNIS BRIDGESI*. 



This species is very common. It is said by the natives to 

 suck the eggs of poultry ; but I rather doubt this statement. 



-j-5. Ceryle torquata. 



This Kingfisher is not very often met with. Its loud note 

 kek-kek-kek is sure to catch the ear if one happens to fly past, 

 so that it is not likely to escape observation ; but I have not 

 seen many specimens. 



6. Ceryle Americana. 



I do not think this species is rare ; but at the same time I 

 saw very few specimens, not more than three or four. 



-J- 7. Ceryle amazona. 



This species is very common. 



8. Campephilus boi^i (Wagl.). 



This species is comparatively rare. It taps on the trees
