The Great Tyrant has been collected by King, Darwin, and 

 Lord Byron in Central Chili — the furthest south it has been 

 hitherto recorded. There, it has hitherto been held to give place 

 to the smaller A. striata discovered by Darwin in Southern 

 Patagonia. It now proves to occur after what appears to be 

 a gap in its distribution. 



The British Museum possesses a series of eight from various 

 localities in Chili, and ten from Northern Patagonia recently 

 acquired. 



The measurements recorded by Dr. Sclater for this species 

 are : — 



Length 9*5, wing 5'0, tail 4*5 inches. 



My Tierra del Fuego birds measure : — 

 c? length 11*8, culmen 1*25, wing 5 '8, tarsus 1*55, tail 4' 9 inches. 

 ? „ 11-6, „ 1-25, „ 5-5, „ 1-5, „ 4-6 „ 



They are olive-brown above, rather than " cinereous " like 

 the Chili birds. 



Northern Patagonian specimens are in agreement with the 

 birds from Tierra del Fuego.
