 brown color more noticeable than the black, occiput and nape similar

 bands, giving somewhat the appearance of dusky vermiculations on the 

 pale brown ground ; interscapulars and upper back barred black and cin- 

 namon, each feather with four cinnamon bands (including the terminal 

 one) ; the feathers of the lower back with the bands reduced in number 

 and restricted to the terminal third or less, only two black bands and 

 these doubly concave distally and the terminal area much washed with 

 grayish, especially posteriorly (in the feathers of the posterior part of 

 the lower back these gray areas are almost pure gray vdth a fine sub- 

 terminal wa\y black line) ; lesser and median upper wing coverts cin- 

 namon to tawny mottled and subbasally broadly marked with black, and 

 with the tips of the shafts white broadening into whitish wedges, which

 mottled with cinnamon; remiges (except inner secondaries) dove brcAAii

 blotches and by irregular fine black lines, the tips grayer, banded irregu- 

 larly with fine black lines ; the rest of the rectrices deep clove browTi to
