REVISION OF THE GENUS MALURUS. 
tail dark delft blue, central feathers narrowly, remainder broadly tipped white 
which continues down outer web of outermost feathers ; under surface white, 
tinged cartridge buff particularly on flanks ; axillaries and under wing-coverts 
pinkish buff, inner margins of wing-quills white. “Bill black ; eyes brown ; 
feet light brown.” 
The female differs markedly from that of other species of 
the genus in having the bill black and the upper surface dark 
blue. Notable in the male is the even colour of head and 
ear-coverts, and the very dark upper aspect of the wing.
