<^, San Sebastian Settlement, 22nd Sept. ; ? , 27th Oct., 1904. 

 Iris — brown ; bill and legs — black. 



Formerly, two species were admitted in this bird — 2L men- 

 talis., of the mainland, and M. macloviana^ of the Falkland

 male the chinspot is more marked than in the female. In this 

 pair there is no such diflference ; the male, however, is a little 

 larger.

 Tierra del Fuego (locality unrecorded). East Falkland Island, 

 Chiloe, and Central and Northern Chili ; and by the French 

 Mission to Cape Horn as far south as Staten Island and Hardy 

 Island in the region of False Cape Horn. 



Bare mountain tops are one of its fiivourite haunts. It 

 also frequents the hummocky flats bordering the sea shore. 

 It is the one living creature I remarked on the bald, wind- 

 swept summit of Nose Peak, 2,225 feet, after eight hours' 

 severe going through well-nigh impassable forest working by

 on the Sierra Carmen Sylva, amidst patches of snow gradually
