THE BIRDS OF AUSTRALIA. 
Gray, that automatically becomes the type by monotypy, and I find that this 
differs from the Australian bird in many details. First it is a larger bird 
with a stouter biU. The wing formula differs, the first primarj^ beinff more 
than half the length of the second which is about equal to the ninth- the 
third, fourth, fifth and sixth primaries subequal, the fourth and fifth equal 
and a httle the longest. 
The tail is of the same formation as the preceding but is much longer 
exceeding the wing in length and more emarginate, the outer tail-feathers 
inclining to twist, and when spread out the tail is still distinctly emarginate 
not square. The hind-toe is stouter and longer.
