112 SYSTEMATIC REVISION OF THE AUSTRALIAN THORNBILLS 
The pallid colouration of this form is in striking contrast 
to the rich green and yellow of typical nana. Milligan des- 
cribed pygmea as being smaller in all dimensions compared 
with mathewsi, but this is not borne out by the type and topo- 
typical material ; indeed, all four forms are markedly similar 
in size. Greater length of bill was the reason for H. L. White 
naming dawsoniana , but one-half to one millimetre in length 
of culmen does not warrant separation. Specimens from 
widely separated localities exhibit this slight difference. 
In his Birds of Australia (ix, 1922, p. 449) Mathews 
erroneously included A. n. modesta as a race of A. lineata, 
giving the range as “North Queensland.” 
ACANTHIZA LINEATA Gould. 
Inhabiting chiefly mountainous and heavily-afforested 
country, the range of lineata is more restricted than that of 
any other species of the genus in eastern Australia. Two races 
can be distinguished, specimens from the south being dis- 
tinctly darker than typical examples.
