Genus— MATTING LEYA. 
Mattingleya Mathews, Austral Av. Rec., 
Vol. I., pt. 5, p. Ill, Dec. 24, 1912. 
Type (by original designation) ... Pachycephala peninsulce Hartert. 
The structural differences I gave as “ Differs from Pachycephala in its longer 
thinner bill, though much shorter wing and tail and weaker feet, with the 
first primary longer proportionately.” 
The first primary is slender and more than half the length of the second 
which is less than the eighth, the third is equal to the seventh and the fourth 
is less than the sixth, the fifth being longest ; the fourth, fifth and sixth 
constitute the tip. 
As will be seen by the accounts of field workers the relationships of this 
group are somewhat obscure ; it is possible that the skeletal features of the 
skull would give some clue to its affinities.
