GOLDEN-BACKED HONEY-EATER. 
“ Differs from M. g. gularis in its paler coloration above, although as dark 
on the under-surface. (Mount Lofty). 
South Australia. 
Mdithreptus gularis Icetior Gould. 
Northern Territory. 
Mdithreptus gularis coongani Mathews. 
“ Differs from iff. g. Icetior in its more pallid coloration, pale yellowish-green

surface. Coongan River, North-west Australia.”

Mdithreptus gularis ingraini Mathews. 
“ Differs from M. g. Icetior in having more green on the upper-surface, and

Mid- Queensland. 
Mdithreptus gularis carpentarianus Campbell. 
North Queensland. 
Mdithreptus gularis validirostris (Gould). 
Tasmania. 
In my 1913 “ List ” I separated the last named specifically, which seems 
certainly necessary in view of the fact that it was generically separated 
by Swainson and the genus admitted by Bonaparte, etc. 
I admitted the others unchanged, but now revision must be made with 
the acceptance of the specific value of M. Icetior, to which four of the above 
must be added. As the type locality of iff. Icetior is Lake Eyre district this 
means that Campbell’s iff. carpentariana is synonymous even as North advised 
me. It will leave the Western Northern Territory bird which I have called 
Melithreptus Icetior northi. 
The subspecies then -will be: 
Melithreptus Icetior Icetior Gould. 
Interior of Queensland, Central Australia and 
Eastern Northern Territory. 
Mdithreptus Icetior ingrami Mathews. 
North Queensland. 
Mdithreptus Icetior northi Mathews. 
Western Northern Territory and adjoining 
parts of North-west Australia. 
Mdithreptus Icetior coongani Mathews. 
Lower North-west Australia.
