Adult male. General colour above dark ashy grey, with obsolete 

 dusky centres to the dorsal feathers; lesser wing-coverts like the 

 back ; median and greater coverts and bastard-wing dusky blackish, 

 edged with ashy grey ; primary-coverts and quills browner, edged 

 with ashy ; upper tail-coverts a little browuer than the back ; tail- 

 feathers brown, margined with ashy ; crown of head ashy grey, 

 rather darker than the head ; forehead blackish, this shade over- 

 spreading the crown almost to the occiput ; eyelid white above and 

 below ; lores, feathers below the eye, and ear-coverts black, the 

 latter washed with ashy posteriorly ; cheeks and throat white, with 

 a black patch ou the chin and upper throat ; rest of under surface 

 white, with a black band across the fore neck ; sides of upper breast 

 mottled with black centres to the feathers ; sides of body and flanks 

 washed with ashy grey, the latter mottled with dark ashy-grey 

 bases to the feathers ; thighs and under tail-coverts white ; under 

 wing-coverts and axillaries white, with a dusky patch near the 

 edge of the wing ; quills below dusky, ashy along the edge of the 

 inner web : " bill yellow ; feet flesh-colour ; iris greyish brown" 

 (Neuivied). Total length 4-3 inches, culmen 0-35, wing 2-25, tail 

 1-85, tarsus 0-55. 



The male in seasonal plumage is washed with olive-brown on the 

 back, wings, and tail, and the head and ear-coverts are ashy grey, 

 the black being visible only on the base of the forehead, lores, and 

 fore part of the ear-coverts. It is evident that in the full plumage 

 the ashy-grey colour becomes abraded and the black spreads over 

 the crown. The black spot on the throat and the band on the fore 

 neck are both overshaded with grey. 



The two specimens from Simacu in the Salvin-Godman collection 

 appear to me to belong to a different species, not having any black 

 whatever on the forehead or lores ; but as they are in seasonal
