Adult male. General colour above blue-grey ; lesser wing-coverts 

 like the back ; median and greater coverts black, tipped and edged 

 with blue-grey; bastard- wing, primary-coverts, and quills black, edged 

 with blue-grey, the inner secondaries broadly edged and tipped with 

 ashy grey ; the inner primaries with a tiny white spot at the base of 

 the outer web, forming an almost obsolete alar speculum ; upper tail- 

 coverts like the back; tail-feathers blackish, edged with grey; 

 crown of head blue-grey like the back, but a little more dusky, as 

 also are the ear-coverts, cheeks, and sides of face ; at the base of 

 the mandible a small white spot ; throat, breast, and abdomen deep 

 chestnut ; entire sides of body and flanks blue-grey ; thighs also 

 blue-grey ; under tail-coverts deep chestnut ; under wing-coverts 

 and axillaries white, the coverts near the edge of the wing slaty 

 grey ; quills below dusky, white towards the base of the inner web : 

 " bill and feet brown ; iris dark brown " (Stolzmann). Total length 

 3 - 2 inches, culmen 0'35, wing 1*9, tail 1-4, tarsus - 55. 



The alar speculum in this species is nearly always hidden by the 

 coverts. The depth of the chestnut colour on the underparts varies 

 slightly in intensity, and in one male from Yquitos the wing-coverts 

 and quills aro washed with olive-green, probably the remains of 

 immature plumage. 



Adult female. Different from the male. General colour above 

 brown, a little lighter and more ruddy on the lower back and rump ; 

 lesser wing-coverts like the back ; median and greater coverts dusky
