This species differs from G. flavolateralis (Grey) from New 

 Caledonia in having a wash of olive brown extending over the 

 head and back of the neck. In G. flavolateralis, these parts are 

 an ashy brown ; the white spot on the tail feathers is nearer the 

 tip on the inner feathers ; the basal portion of the feathers below 

 is white, and the undertail-coverts are white ; the tips of the 

 feathers more rounded, the throat and breast are white, no olive 

 brown on the wings or back, the olive tint of these parts is of a 

 yellowish tinge ; the bird is altogether smaller.
