Graucalus novcehollandice Mathews, Birds Austr., Vol. IX., pt. nr., p. 110, pi. 413, June 20th, 1921. 
Distribution : Gascoyne River and district. 
Type male. All the upper-surface from the forehead to the upper tail-coverts French grey, including 
the wing-coverts ; forehead lighter ; central tail-feathers with grey bases, then a wide 
band of greyish-brown, and tipped with white ; remaining feathers black, the out web 
of the outer tail-feather white towards the end, which has a wide white tip ; this white 
decreases in extent towards the middle feathers ; lores and an increasing band through, 
and below the eyes, extending on to the ears and cheeks, black ; throat white, each feather 
flecked with grey ; lower throat and breast light French grey, with the shafts of the feathers 
showing darker ; sides of the body similar ; belly, abdomen, and vent white ; primaries 
black edged with white ; secondaries black with the outer web getting w biter, to the tertials ; 
axillaries and under wing-coverts white. Eyes almost black, with a narrow 7 brown outer ring ; 
feet and bill black. Total length 325 mm. : wing 186 ; eulnien 21 ; tail 148 ; tarsus 29. 
Figured. Collected on Jerrvnew 7 or Jacobs Creek, Gascoyne, Mid-west Australia, on October 
2nd, 1927. 
This bird differs from immature novcehollandice in having the throat white, not 
black. It resembles the immature figured by me in Vol. IX., pi. 413, from Mungi, 
but has the throat almost white and the breast not so dark grey; the white 
edges to the wing feathers is also more extensive. 
Whether this is a case of arrested development is, perhaps, worth while 
considering. 
In a skin kin dly sent me by Mr. Glauert, of the Perth Museum, West 
Australia, collected at Nullagme, N.E. of the Gascoyne River, we find the chin 
and throat to be black with many white feathers interspaced. In the upper 
surface it is practically a match with gascoynensis.
