RED-THROAT. 
k 
Although this bird was known to range from East to West Australia no 
forms were distinguished until I admitted in my “ Reference List ” in 1912, 
two only : 
Sericornis brunnea brunnea (Gould). 
New South Wales, Victoria, South Australia. 
and 
Sericornis brunnea pallescens Mathews. 
“ Differs from S. b. brunnea in its paler upper-surface coloration and its almost 
white under-surface. Bore Well, West Australia.” 
West Australia. 
I reinstated the correct genus name Pyrrholcemus in my 1913 “ List ” but 
only recognised the two above mentioned as : 
Pyrrholcemus brunneus brunneus Gould. 
East Australia. 
and 
Pyrrholcemus brunneus pallescens (Mathews). 
West Australia. 
No new forms have since been named although Milligan pointed out that 
two forms appeared different in West Australia. 
Apparently the pallid form which I named from Bore Well extends to the 
North West and the Wongan Hill bird differs as Milligan wrote. 
The Wongan Hills form may be called : 
Pyrrholcemus brunneus milligani susbp. nov. 
and I note the flanks are brownish, the upper-surface is browner above and the 
throat is darker. 
However from the Southern Cross, Kalgoorlie, etc. there comes a very 
distinct unexpected form as it is much darker. I name it \ 
Pyrrholcemus brunneus kalgoorlie subsp. nov. 
This form is darker-brownish above, has a darker red throat, a darker grey 
breast and darker brown flanks and is also larger. 
There are probably many subspecies in the East also, as Captain S. A. 
White has noted the Lower Murray bird differed, but he did not say with which 
of his birds he compared it. Of course the Lower Murray bird was the typical 
bird and I now name the Central Australian bird : 
Pyrrholcemus brunneus centra subsp. nov. 
as being lighter above and the throat a deeper red.
