I have two " Bogota " 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.

Mus. P. L. S, 



I have hitherto called this second Chilian species /w^coic^es 

 (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. mayel- 

 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," according to Philippi and 

 Landbeck, whereas S. mageUanicus is called "■ Chercan negro."
