Adult. Closely allied to 0. i/iUtiUi, but smaller, and differing in 

 having a wide white superciliary stripe produced backwards along 

 the sides of the neck above the ear-eoverts ; lower back and rump 

 dark olive-brown like the mantle, in which respect it resembles 

 0. carctcco ; the chest and upper breast have an indistinct whitish 

 spot at the extremity of each feather ; the four outer pairs of tail- 

 feathers are tipped with chestnut, the third pair being almost as 

 widely tijiped as the fourth, and in this respect differing from the 

 other allied species, which rarely have any chestnut on the third 

 pair, and then only a small patch at the extremity. This species is 

 also very closely allied to 0. araucuan, and resembles it in size, but 

 is distinguishable by its white eyebrows and indistinctly spotted 

 breast. Total length about 17 inches, wing 6'S, tail 7'2, tarsus 1'8, 

 middle toe and claw 1"S.
