typical brasilianus may be mentioned the deep buff or ochraceous outer 

 webs of the scapulars, iuner webs of the ear-tufts, and indeed all the 

 markings of the upper surface, which are white in that form ; these 

 peculiarities being among the distinguishing features of the itstus type. 

 This specimen, however, is from Sta. Catariua, S. E. Brazil. It belongs 

 to the collection of Messrs. Salvin and Godman. 



In his description of this form, Mr. Sharpe describes what he terms 

 its "gray phase", but which seems to be decidedly more brown than 

 gray, and, to judge from the description, quite different from anything 

 I have seen. I quote the essential parts of the descriptions of this 

 form given by Mr. Sharpe : — 



"Adult male (gray phase). General color above dull earthy brown, 

 so finely vermiculated as to appear almost uniform at first glance, a 

 few fulvescent cross markings more conspicuous on the scapulars and 

 secondaries, very slightly indicated on the hind neck, and not forming 

 a distinct collar; crown of head rather blacker than the back, the 

 feathers infinicesimally freckled with sandy rufous, the ear-tufts blackish, 

 scarcely vermiculated at all ; ear-coverts sandy brown, indis- 

 tinctly barred across with blackish brown, and narrowly shaft-streaked 



with white ; rest of under surface ochraeeous buff, thickly 



sprinkled with wavy lines and vermiculations of dark brown, especially 

 on the side of the chest, some of the breast feathers streaked with 

 black and barred across with white, the flanks scantily barred with 

 dark brown, inclining to white near the tip, the markings scanty, as 



also on the under tail-coverts Total length 9.5 inches, wing 



6.G, tail 3.9, tarsus 1.3. 



"Adult female (ru r ous phase). General characteristics as in the gray 

 phase, but rufous where the other bird is brown, and slightly more 

 mottled on the upper surface with rufescent cross bars ; below nearly 

 uniform rufous, deeper on the chest, some of the feathers slightly 

 streaked with black, more narrowly on the breast and abdomen ; on the 

 chest a few dull brown vermiculations, the abdomen indistinctly barred 

 with fulvous. Total length 9 inches, Aving 6.55, tail 3.4, tarsus 1.3. 



" Obs. The principal characteristics of this race are the uniformity of 

 its upper surface, and the comparative absence of streaks ; scapulars 

 fulvescent, not white. These remarks apply both to the brown and 

 rufous phases, neither of which shows any collar on the hind-neck.
