Genus— M ACCO YORNIS. 
Maccoyornis Mathews, Austral Ay. Rec., Vol. I., 
pt. 5, p. 113, Dec. 24th, 1912. Type (by 
original designation) ... ... ... ... Sphenura broadbenti McCoy.

and legs, and in the longer wing and tail.” 
This is a peculiar evolution, as it is a large form of Dasyornoid relation, 
intervening between the two known species from East and West Australia, 
while it has a representative in Western Australia living, as far as we know, 
alongside a true Dasyornis. It is unfortunate that a long enough series of 
all these species cannot be secured to decide their relationships exactly, as 
at the present time we cannot dogmatise with any certainty, and it is probable 
that the Western Maccoyornis may be specifically distinct.
