SYSTEMATIC REVISION OF THE AUSTRALIAN THORNBILLS 99 
3, Acanthisa reguloides reguloides ; 3a, A. r. squamata; 3b, A. r. australis. 
Acantliiza reguloides squamata De Vis. 
Acanthisa squamata De Vis, Proc. Roy. Soc. Queensld., vi, 1889, p. 248; 
Herberton, Queensland. 
Range. — From vicinity of Cairns, north-eastern Queensland, south to the 
Dawson River. 
Specimens Examined. — Two from Herberton, and Rio Station, Dawson 
River. 
Measurements. — Male and female respectively: wing, 53, 50; tail, 39, 40; 
exposed culmen, 9, 9; tarsus, 17, 16. 
Subspecific Characters. — Much lighter in colouration than A. r. reguloides 
and A. r. australis. Upper surface from greyish olive on crown to citrine-drab 
on rump ; upper tail-coverts straw yellow ; under surface barium yellow. 
The scarcity of material from east coastal Queensland is 
again apparent in the number of specimens available of this 
race, but there is no question as to its validity. The Dawson 
River specimen is slightly darker than the one from Herber- 
ton, the type locality, and as two specimens of A. r. reguloides 
from Gayndah to some extent approach this race it would 
appear that intergradation with reguloides takes place in the 
area south-east of the Dawson River and north of Gayndah. 
Although the relationship of this form and A. r. reguloides 
is obvious, it was erroneously included as a race of chrysor- 
rhoa by Mathews (Birds of Aust., ix, 1922, p. 465).
