Chapman, The Standing of Ardetta neoxena. 



TAuk 

 Ljan. 



Outer secondaries slate gray with- 

 out cinnamon rufous tips; inner 

 secondaries black, glossy on the 

 outer web and without chestnut 

 rufous. 



Lesser wing-coverts at bend of 

 wing black. 



Median wing-coverts chestnut. 



Greater wing-coverts blackish 

 slate gray, the inner ones with chest- 

 nut tips. 



Under wing-coverts chestnut. 



Outer secondaries slate gray 

 tipped with cinnamon rufous; inner 

 secondaries with outer web chest- 

 nut rufous, inner web blackish slate 

 gray. 



Lesser wing-coverts at bend of 

 wing chestnut rufous. 



Median wing-coverts cream buff. 



Greater wing-coverts with basal 

 half slate gray, terminal half chest- 

 nut rufous, the inner ones washed 

 with cream-buff on the outer vane. 



Under wing-coverts white, graver 

 at the base, and washed with buffy. 



It will be seen from this comparison that there is no regularity 

 in the substitution of colors ; hence these birds differ not alone 

 in color, but also in pattern of coloration. Thus, the chestnut 

 of neoxena may replace either the white or buff of exilis, or the 

 former may be black where the latter is chestnut rufous, buff, or 

 white. The differences in distribution of color, or relative mark- 

 ings of the same parts, are most marked in the interscapulars, 

 under tail-coverts, greater wing-coverts, and tips of the quills. 



Ardetta neoxena, $ ad. 



Similar to male but crown slightly, 

 and back decidedly duller. 



Ardetta ex His, J ad. 



Similar to male but black of head 

 tinged with brown; back rich, dark 

 brown ; interscapulars more widely 

 margined with buffy ; under parts 

 more heavily washed with buff, and 

 with numerous blackish shaft- 

 streaks, and in places slight blackish 

 mottliners.

My notes on the female of neoxena are based on the original 

 records and Mr. Hubert Brown's comparison of the two adult 

 Toronto females, neither of which I have seen. One of these
