TJENIOPTERA ALPINA, Jardine. 
We cannot identify tliis species with any of those described in works 
devoted to the natural history of Chili or Peru, though it seems to 
resemble the bird figured by Tscliudi, under the name of Ptyonura 
albifrons . As already stated, it occurs on the highest ridges of 
the Andes, rarely descending below the snow limit; and from its 
general appearance, at once conveys the idea, that it performs 
there the ofi&ce of the saxicoline birds of Europe. 
The crown, cheeks, nape, back and wings, are brownish -grey, 
having in some sj)ecimens a more umber tint ; the quills are brownish- 
black ; from the nostrils to the eyes, and shading gradually over 
them is white ; the rump, upper tail-covers and tail are black — the 
outer feather of the latter edged with greyish-white ; the throat 
and breast are pale brownish-grey, shading into white on the belly, 
vent, and under tail-covers ; the bill, the feet, and tarsi, are black 
—the latter very saxicoline in form. 
The entire length, 7 ; bill to forehead, 6 ; to gape, 9 ; wing, 4.9 
t° 5.5; tail, 3 .4 to 5 ; tarsus, i .2 to ’ 3 .
