THE BIRDS OF AUSTRALIA. 
Continuing this view in my 1913 “ List ” I admitted : 
Hylacola pyrrhopygia pyrrhopygia (Vigors and Horsfield). 
New South Wales. 
Hylacola pyrrhopygia belcheri Mathews. 
Victoria. 
Hylacola cauta cauta Gould. 
South Australia. 
Hylacola cauta halmaturina Mathews. 
Kangaroo Island. 
Hylacola cauta brevicauda Mathews. 
Victoria. 
Hylacola cauta whitlocld Mathews. 
South-west Australia. 
Later F. E. Howe made a study of the species and admitted the forms 
named ; he later added another : 
Hylacola pyrrhopygia magna 
from Cobbora, New South Wales, as being paler above and below, eyebrow 
whiter, striping on throat and breast more linear and tips of outer tail-feathers 
whiter and broader, and also larger in size generally. Consequently two 
species with seven subspecies were admitted, but I am disposed to consider 
them all only subspecifically related, especially as some of the subspecies differ 
more from each other than the “ species ” do. As it is considered certain 
that these are relations of Calamanthus that conclusion should be logical, unless 
we recognised many species of the latter genus. Moreover, Howe has noted 
that perplexing specimens occur and consequently the plumage changes are 
not absolutely known. With regard to the geographical distribution it will 
be noted that none of the forms overlap and that authorities have found 
difficulty in distinguishing the species. 
This would consequently allow : 
Hylacola pyrrhopygia pyrrhopygia (Vigors and Horsfield). 
New South Wales (coastal) ? into Northern 
Victoria. 
Hylacola pyrrhopygia magna Howe. 
New South Wales (interior). 
Hylacola pyrrhopygia belcheri Mathews. 
Victoria (coastal). 
Hylacola pyrrhopygia brevicauda Mathews. 
Victoria (mallee). 
Hylacola pyrrhopygia cauta (Gould). 
South Australia (mallee).
