 crown with numerous elliptical (longitudinal) marks of white, feathers everywhere with 

 large partly concealed spots of the same; these spots largest on the neck and scapulars 

 on the latter of a roundish form, the outer webs of those next the wing being almost 

 wholly white, the edge only brown; on the nape the spots form V-shaped marks, the spots 

 themselves being somewhat pointed ; below this is a transverse, less distinct collar, of 

 more concealed spots; wing-coverts, toward the edge of the wing, with a few large, 

 nearly circular, white spots; secondaries with two transverse series of smaller white 

 spots, these crossing about the middle, remote from the end and base; outer feathers of 

 the alula with two white spots along the margin; primary coverts plain; primaries with 

 four or five transverse series of white spots; 'tail with the same number of narrow trans- 

 verse spots, forming interrupted bands, the spots not touching the shaft the last spot not

 spots of white, these either median or upon only one web; across the throat the circle 

 becomes paler brown, without the white spotting. Eyebrows and face grayish white; 

 lores and eyelids blackish. Lower parts white, becoming pale ochraceous on the legs;
