Adult. Head and nape dark brown ; superciliary streak and region of the cars tawny, the former freckled 

 with brown; back of neck and lower part of back dark purplish brown varied with buff; mantle, 

 scapulars, and secondaries dark brown with purplish reflexions, freckled, and mottled on the edges with 

 tawny yellow; upper surface of wings pale buff, the longer coverts with broad arrow-head marks 

 along their whole extent, and the shorter ones freckled and mottled with different shades of brown ; 

 primaries purplish brown, with dark shafts, marbled on their inner webs with buff; secondaries darker 

 brown, marbled on both vanes, but more conspicuously on the inner; tail-feathers dark brown, mar- 

 gined and freckled with buff, especially on the outer ones; throat, front and sides of the neck, and all the 

 under surface tawny buff, variegated with dark brown ; on the throat the brown markings are very indi- 

 stinct, being limited to a narrow freckled line down the middle; on the fore neck each feather has a 

 broad mark of yellowish brown down the centre, with vandyked edges in some and lateral continuations 

 in others ; on the long neck-plumes which overhang the breast, and on the overlapping femorals, these 

 markings assume the character of narrow zig-zag lines and arrow-heads. The broad feathers coverings 

 the upper part of the breast are blackish brown in the centre with tawny-white sides ; but these are 

 usually concealed by the overhanging plumes of the fore neck ; on the sides of the body there are irre-
