dominate ; on the head the pi'edominant color is black, the feathers 

 being merely edged laterally with rufous; on the cheeks the black 

 is nearly uniform. Lining of the wing rich chestnut the rufous 

 broken by darker and lighter spotting ; inner webs of primaries 

 ash-gra} r , with indistinct, very narrow, deeper-gra}', oblique bars. 1 



The tail-feather (middle one) of the new moult, completely 

 grown, is colored as follows: The prevailing color is silvery-gray, 

 but this changes gradually to white along the shaft, but toward 

 the end this gives way to a subterminal band of deep black, about 

 one inch wide, and distant half an inch from the end; the re- 

 mainder, or gray portion of the feather, is crossed by about 

 twelve narrow, zigzag bars of deeper gray, these becoming gradu- 

 ally more indistinct basally, where they are broken into a con- 

 fused mottling. 



A young male, supposed to be from Chile (No. 1624, Museum of 

 the Wesleyan University, Micldletown, Connecticut) is colored as 

 follows: Tail dull brownish-gray to the tip, crossed by numerous 

 (more than fifteen) narrow bars of dusky; remiges dull brownish- 

 slate, distinctly banded with bars of dusk} T black; rest of upper 

 parts nearly uniform blackish-brown, slightly variegated (more 

 heavily on upper tail-coverts) with ocbraceous. Head blackish- 

 brown, faintly edged with ochraceous, with a large, plain, ochra- 

 ceous area on the auricular region. Lower parts (except throat) 

 ochraceous-white, with sharply -defined, broad, longitudinal stripes 

 of blackish-brown ; tibise with irregular hastate spots of rufous ; 

 crissum with sparser, finer markings of the same. Lining of the 

 wing ochraceous-white, with large but not crowded spots of brown- 

 isb-black ; inner webs of primaries white, marbled along the edge 

 with slate.

1 This is the character of the quills of the new moult ; several old ones, 

 which were not cast, are pure white instead of ash, the bars of the same 

 shade as in the new feathers.
