THE BIRDS OF AUSTRALIA. 
may not inosculate, as they appear to be so well differentiated as far as we 
know them at present. 
The northernmost form lacks the red frontal band and the dark nape, 
while the Flinders Range form has the nape coloration of the typical form 
extending over the top of the head, the frontal red band is retained 
though paler. It will be noted that the forehead coloration was regarded as 
of specific value by Salvadori in this genus, but criticism of a long series shows 
it only to be an individual feature. 
The back is pale bluish green in the northern form, and a dark bluish 
back at the other extreme, but the Flinders Range form has a blue green 
back and rump, the rump in the typical form being paler and contrasting 
with the back. 
The undersurface coloration is variable in the typical form, being pale 
green or blue-green with a narrow band of yellow feathers across the lower 
breast, sometimes sprinkled with red, while at others altogether missing. The 
northern form has the upper breast paler, but the lower breast and abdomen 
orange, the under tail-coverts being, however, green. The under surface 
coloration of the Flinders Range form is more bluish on the upper breast, and 
greyish on the abdomen, a broad orange band across the belly. 
Three subspecies can be thus still recognised. 
Barnardius barnardi barnardi (Vigors and Horsfield). New South 
Wales (Interior) : Mallee of Victoria and South Australia. 
Barnardius barnardi macgillivrayi North. Interior Mid-Queensland. 
Barnardus barnardi whitei Mathews. Flinders Range, South 
Australia. 
Of the last named Platycercus barnardi auyustus Mathews and Barnardius 
barnardi lindoi S. A. White are synonyms.
