100 SYSTEMATIC REVISION OF THE AUSTRALIAN THORNBILLS 
Acanthiza reguloides australis (North). 
Geobasileus australis North, Aust. Mus. Spec. Cat., i, 1904, p. 287 ; 
Woodside, South Australia. 
Acanthiza reguloides connectens Mathews, Nov. Zool., xviii, 1912, p. 
352 ; Ringwood, Victoria. 
Acanthiza reguloides grampianensis Ashby, Emu, xxvi, 1927, p. 290; 
Hall’s Gap, Grampian Range, Victoria. 
Range . — From south-eastern New South Wales, south and west to the 
vicinity of Adelaide, South Australia. 
Specimens Examined . — Nineteen from the following localities: Victoria: 
Fernshaw, Healesville, Whittlesea, Lower Plenty River, Springvale, 
Croydon, Kilsyth, Bayswater, Muddy Creek, Parwan, Raywood, Nhill, 
Winiam. South Australia: Mt. Lofty, Upper Sturt, Callington, fifty miles 
south of Pinaroo. 
Measurements . — Nineteen adult specimens of both sexes: wing, 50-56 
(52 7); tail, 37-44 (39 2); exposed culmen, 9-10 (91); tarsus 16-17 5 
(16-6). 
Subspecific Characters . — Differs from both A. r. reguloides and A. r. 
squamata in its darker colouration throughout. Dorsal surface dark olive 
rather than deep greyish olive of typical reguloides ; upper tail-coverts honey 
yellow; tail basally pinkish cinnamon, feathers margined honey yellow; 
lower ventral surface naples yellow. 
Victorian material examined is representative and is plainly 
to be referred here. The dark, more huffy, under surface as 
distinct from yellow in reguloides and squamata is a feature 
of this form. 
ACANTHIZA I NO It NAT A Gould. 
It has been remarked that this species is closely related to 
A. nana, but a careful examination reveals that inornata is 
more closely allied to iredalei and reguloides , although all 
three are specifically distinct. 
From the series examined two forms appear worthy of 
recognition. 
Acanthiza inornata inornata Gould. 
Acanthiza inornata Gould, Proc. Zool. Soc., 1840, p. 171 ; Swan River, 
Western Australia. 
Acanthiza inornata carnarvoni Mathews, Aust. Av. Rec., ii, 1913, p. 
76; Carnarvon, Western Australia. 
Acanthiza inornata strcllyi Mathews, ib . ; Strelly River, Western Aus- 
tralia. 
Range . — Coastal Western Australia from the De Grey River south, except 
extreme south-west. 
Specimens Examined . — Eleven from the following localities: Solomon’s 
Wells, Lake Yanchep, Perth, Guildford, Kelmscott, Brookton.
