42 FALCONID^. 



freckled with dark brown, except the extremities of the feathers, 

 which do not, however, show a very distinct band. 



The tjT)e of Mr. Gould's M. hyperstictus is in the Museum, and is, 

 I believe, the very old bird of this species in bleached plumage. At 

 the same time it presents many differences from the bird which I 

 have considered to be the adult, viz. in the breadth and purity of the 

 white margins of the back-feathers, in the pure white primary coverts 

 which are not freckled, but show five narrow brown cross bars, and 

 especially in the total absence of any subterminal bar on the taU- 

 feathers. The latter are ochraceous buff, with narrow greyish brown 

 bars on the inner webs, broader and more vermiculated on the 

 outer; the two centre feathers entirely covered with ashy-brown 

 frecklings. 



Hah. The southern portion of the South-American continent and 

 Tierra del Fuego, '-anging on the west coast as high as 20° S. lat. ; 

 but in the central portions not higher than the Tropic of Capricorn, 

 and only extending in Eastern Brazil to the districts north of E.io.
