buff, with a few tiny spots of brown near the outer edge of the wing, 

 the lower series ashy bro\ra, resembling the quill-lining ; scapulars 

 externally yellowish buff, barred with dark brown, a few of the 

 wiiig-coYcrts also largely spotted with yellowish on the outer web, 

 the wing-coverts otherwise tolerably uniform like the back, the 

 vermiculations a little more distinct ; primary coverts dark brown, 

 regularly barred across with sandy buff rather obscured with brown 

 vermiculations ; quills dark brown, barred with sandy buff, inclining 

 to yellowish on the inner webs, the secondaries so closely vermi- 

 culated on the outer web that the light bars are nearly obscured, 

 being, however, much more distinct on the outer webs of the pri- 

 maries, inclining to white on the margins of the latter, and producing 

 a chequered appearance ; tail dark brown, thickly vermiculated with 

 sand}' buff on the margins and at the tips, and crossed with bars of 

 the same, eight or nine of which are distinguishable. Total length 

 9-5 inches, wing 6-(5, tail 3-9, tarsus 1-3. 



Adult female (rufous phase). General characteristics as in the grey 

 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, wing 6-55, taU 3"4, 

 tarsus 1*3. 



Ohs. The principal characteristics of this race are the uniformity 

 of its upper surface, and the comparative absence of streaks ; sca- 

 pulars fulvescent, not white. These remarks apply both to the 

 brown and rufous phases, neither of which shows any collar on the 

 hind neck.
