black ; breast and flanks olive brown ; centre of the abdomen and under 
tail-coverts, buff ; bill, horn colour ; feet, black. 
Habitat, Santa Cruz, Patagonia. {April.) 
I am not aware of any difference in habits between this species, and the fol- 
lowing (A. micropterus) ; and the country inhabited by it is similar. From these 
circumstances I am induced to suspect, that it is the same species in an immature 
state.

Head, all the upper surface, wings and tail, pale brown, each feather of the wings 
and tail margined with greyish brown ; throat, white, striated with dark 
brown; the remainder of the under surface, huffy white; bill, dark horn 
colour ; feet brown. 
Habitat, Port Desire, and St. Julian, Patagonia. {January). 
These birds frequent the wild valleys in which a few thickets grow. They 
generally take their stand on the upper twigs. They are shy, solitary, and not 
numerous. Mr. G. R. Gray considers the two specimens which were obtained 
to be immature, and that one is a full-fledged young, and the other a nestling 
of the Agr. striatus.

Inhabits the coast of Patagonia. It is a scarce, shy, solitary bird, frequent- 
ing the valleys in which thickets grow, but often feeding on the ground. In the 
interior plains of Patagonia, on the banks of the Santa Cruz, I several times saw it 
chasing beetles on the wing, in a peculiar manner, half hopping and half flying ; 
when thus employed, it spreads its tail, and the white feathers in it are displayed 
in a very conspicuous manner. I also met with this species in the lofty and arid 
valleys on the eastern side of the Cordillera of Central Chile, and likewise at 
Copiapo.
