THE BIRDS OF AUSTRALIA. 
I have now re-considered the whole of the available material and find one 
of the chief stumbling blocks to the above arrangement is the Cape York 
minimus and the Icevigaster forms. Campbell has pointed out that the eggs 
of minimus differ appreciably and apparently in a specific manner. The 
acceptance of tins would necessitate the recognition of at least three species : 
Sericornis minimus Cape York. 
Sericornis Icevigaster Rest of Queensland and Tweed River District, 
Yew South Wales. 
Sericornis frontalis Coastal Yew South Wales and East Victoria. 
Of the last named the above subspecies can be admitted, taking away 
Icevigaster and minimus, making a total of five.
