I have two “ Bogota 99 skins, which I refer to this species 
of Lafresnaye. They do not, however, show any white on 
the forehead or wing-coverts, such as Lafresnaye describes. 
But my specimens are not quite adult.

I have hitherto called this second Chilian species fuscoides 
(see P. Z. S. 1867, p. 325). But it is certainly the bird pre¬ 
viously described by Gay as S. obscurus, and may probably be, 
as Gay supposes, the Sylvia obscura of King. 
This species is easily distinguishable from the S. magel- 
lanicus by its larger size, more cinereous colour, longer tail, 
and the faint bars across the rump and lower belly. Its ver¬ 
nacular name in Chili is “ Cher can, 33 according to Philippi and 
Landbeck, whereas S. magellanicus is called “ Cher can negro. 33
