660 ATRICHIID^. 



circular markings of black, one of them subterminal, and the other 

 iu the centre of the feather, so that the black and brown colours 

 alternate ; the head and ramp similarly marked, but not so dis- 

 tinctly : wing-coverts and quills dusky brown, varied with rather 

 more rufcscent brown than the back, the feathers being edged with 

 rufescent brown, taking the form of notches on some of the quills ; 

 many of the greater coverts and inner secondaries patterned like 

 the back, with a subterminal and median line of black, alternating 

 with the brown colour of the feather ; upper tail-coverts like the 

 back ; tail-feathers black, varied with alternate wavy markings of 

 brown and black on the margins ; lores, sides of face, and ear-coverts 

 dusky brown, the latter someM'hat ashy ; feathers round the eye 

 varied with fulvous spots, with a few whitish streaks on the fore 

 ]iart of the ear-coverts ; cheeks dark ashy ; throat and breast white, 

 fading off into tawny rufous on the abdomen, which becomes deep 

 tawny rufous or chestnut on the lower abdomen and vent ; thighs 

 and under tail-coverts paler tawny rufous, the latter mottled with 

 blackish cross bars ; centre of throat dull ashj-, developing gradually 

 into a large patch of dark ashy grey, which occupies the lower 

 throat and fore neck, leaving the breast white : sides of breast 

 brown, slightly varied with cross bars of black ; under wing-coverts 

 and under surface of quills dusky brown : " bill horn-colour ; iris 

 dark brown" (./. Gould). Total length 8'5 inches, culmcn 0*75, 

 wing 3-1, tail 4*1, tarsus 1-05. 



This species has a very distinct seasonal plumage, in which the 

 blackish throat-patch becomes obscured by whitish edges, so that 

 the throat and breast are white with the black patch concealed. 

 Whether the full plumage is gained by the shedding of these white 

 edges I have not had the means of discovering.
