 these streaks sometimes expanded into a spot terminally; under wing- 

 coverts buffy white or very pale dull buff (along edge of wing more 

 decidedly white), with a series of broad longitudinal streaks of gray- 

 ish brown running parallel with edge of wing ; under primary coverts

 cinnamon-rufous, no trace of bands being visible, though usually 

 these are more or less indicated, often distinct and sharply defined ; 

 streaks on pUeum and hindneck pale cinnamon-rufous, instead of 

 white, and usually much less distinct than in brown phases; markings
