THE BIRDS OF AUSTRALIA. 
Professor Collett,* who described this bird, says : “ This Pigeon was met 
with in flocks in the central portions of Arnhem Land about the sources of the 
South Alligator River. It inhabits the stony parts of the sandstone hills ; it 
lies close amongst the stones, and knows well how to conceal itself amongst 
them when wounded.” 
The bird figured is a male collected on South Alligator River by Mr. J. T. 
Tunney on the 1 0th August, 1903.
