THE BIRDS OF AUSTRALIA. 
I separated the Melville Island birds, but upon criticising a good series 
I find that though the head appears generally brighter and the belly darker, 
the differences are not marked enough for recognition in this place, accepting 
a conservative standard of subspecific values. Of course, if it were a 
Palsearctic form, the Melville Island would unhesitatingly be recognised, 
but at the present time I consider the Palsearctic standard too fine for 
general work among Australian birds.
