tawny on the abdomen, sides and under tail coverts, some of the feathers 

 with gray shaft streaks ; bill and feet black. 



Worn breeding birds (January 17, 1898) are much paler and are some- 

 what mottled above by the exposure of darker bases to the feathers ; the 

 olive tint, too, is lost but they are always more pure ashy below than 

 above. 



Geographical Range. — Paraguay and Argentina throughout Patagonia. 



This conspicuous flycatcher was taken in southern Patagonia in late 

 September and January, both records being from nearly the same point 

 in the extreme southeastern part of the region, Rio Coy and Palli Aike. 

 It would therefore appear that at least some of the birds remain in this 

 part of Patagonia throughout the year, while most representatives go fur- 

 ther north into Uruguay in the colder months. 



Both specimens of this bird collected by Mr. Hatcher and his assistants 

 are females and are fully adult. They are much smaller in their wing 

 measurements than are the specimens described by Dr. Sclater, his aver- 

 age of nine birds giving him a wing measurement of 6.7 inches (Sclater, 

 Cat. Bds. Brit. Mus. xiv. p. 9, 1888), while neither bird from southern 

 Patagonia exceeds 5.90 inches in wing length. It may be found that 

 there is a separable smaller form characteristic of this part of Patagonia, 

 but at present the material for study is not sufficient to base conclusions 

 upon.
