214 BIRDS OF AUSTRALIA. 



feathers margined with grey ; throat white, bounded below 

 by a distinct crescent of black : abdomen, flanks, and under 

 tail-coverts orange -brown ; tail dark brown, the basal portion 

 of the webs edged with grey ; irides reddish brown ; bill 

 black ; feet blackish brown. 



The adult female has the crown of the head and all the 

 upper surface grey ; ear-coverts brownish grey ; throat bufFy 

 white, passing into light buff or fawn-colour on the chest, 

 flanks, abdomen, and under tail-coverts ; the feathers of the 

 throat and chest with a narrow dark line down the centre ;

 the throat whiter, and the markings on the chest much more 

 distinct and extending over the abdomen also. 



In very young individuals a rich rufous or tawny tint per- 

 vades the greater part of the upper surface.

 upon this kind of food. 



No information whatever has been obtained with respect 

 to its habits and economy ; this blank therefore remains to
