innermost secondaries and inner upper wing-coverts white ; remainder of 
wing fuscous, upper-coverts tipped or margined phenyl blue, outer margins of 
wing-quills bluish gray ; tail dusky greenish-blue, margins of outer webs of 
feathers lighter and of inner webs fuscous ; axillaries and under-wing-coverts 
black excepting those of the latter at edge of wing which are blue, inner margins 
of wing quills noticeably lighter. "Bill black ; eyes deep brown ; feet dark 
brown.” 
Female. — Upper surface, including upper wing-coverts wood-brown ; wing 
quills hair-brown, outer margins of secondaries wood brown and those of 
primaries much lighter ; tail drab, indistinctly suffused with blue and lighter

particularly on flanks and under tail-coverts j axillaries, under wing-coverts 
and inner margins of quills pinkish buff. "Bill pink horn ; eyes umber ; feet 
light brown.” 
The validity of leuconotus as distinct from leucopterus Vigors 
and Horsfield = cyanotus Gould (not leucopterus Dumont) has 
long been doubted. The type has been lost and no other 
specimen was recorded until 1924 when Kinghorn and Iredale 
(Emu, 24, p. 59) published an account of one taken at Mount 
Lyndhurst, South Australia, agreeing with the original descrip- 
tion. This specimen (which I have had the opportunity to 
examine) exhibits a tinge of blue, especially towards the tips,
