THE BIRDS OF AUSTRALIA. 
South Wales. I therefore synonymised this with the typical subspecies and 
differentiated the other forms thus : 
Acanthiza chrysorrhoa chrysorrhoa (Quoy and Gaimard). 
New South Wales. 
Of this Acanthiza leighi Grant from Lithgow, New South Wales is a synonym. 
Acanthiza chrysorrhoa sandlandi 
“ Differs from A. c. chrysorrhoa in lacking the greenish tinge on the under- 
surface, the flanks being light fawn. (Blackburn) Victoria.” 
Victoria. 
Acanthiza chrysorrhoa leachi 
4 4 Differs from A. c. sandlandi in its larger size, longer bill, and having the 
feathers on throat distinctly fringed with brown. Tasmania.” 
Tasmania. 
Acanthiza chrysorrhoa perlcsi 
44 Differs from A. c. sandlandi in having the flanks rufous-buff, less spotting on 
the head, and paler coloration above (Mount Lofty) ” 
South Australia. 
Acanthiza chrysorrhoa multi 
44 Differs from A. c. perlcsi in having the flanks darker, and more white on the 
abdomen. Wilson’s Inlet, West Australia.” 
South-West Australia. 
Acanthiza chrysorrhoa pallida Milligan. 
Very pale throughout from Murchison. 
Mid- West Australia. 
At that time De Vis A. squamata was not recognised as referable to this 
species, but was attached to A. reguloides. 
Receipt of specimens from South Australia showed that the Port Augusta 
form differed from the Mount Lofty birds in “ being paler above and whiter on 
the chest ” and these I named: 
Acanthiza chrysorrhoa addenda 
and these were included in my 1913 “ List.” I there reinstated the genus 
Geobasileus for this group, and also transferred De Vis squamata to this species 
so that the names then read : 
Geobasileus chrysorrhous chrysorrhous Quoy and Gaimard. 
Geobasileus chrysorrhous sandlandi Mathews. 
Geobasileus chrysorrhous leachi Mathews. 
Geobasileus chrysorrhous perlcsi Mathews. 
Geobasileus chrysorrhous addendus Mathews. 
Geobasileus chrysorrhous multi Mathews. 
Geobasileus chrysorrhous pallidus Milligan. 
Geobasileus chrysorrhous squamatus De Vis.
