and is Platycercus zonarius occidentalis (North). 
Adult females from the same locality are similar.

deep blue on the outer-webs except the secondaries which are green on the outer 
webs ; the four middle tail-feathers similar in colour to the back with paler tips, 
the outer feathers for the most part blue becoming very pale at the tips ; crown 
of head and nape dark brown with a slight tinge of green on the forehead ; sides of

Total length 395 mm. ; culmen 22, wing 172, tail 209, tarsus 20. Figured. Collected 
at Lake Dundas, South-west Australia, on the 24th of May, 1905, and is my type 
of Platycercus zonarius dundasi. 
Adult males from the same locality are similar. 
Immature are duller all over. 
Nest. A hole in a tree. 
Eggs. Clutch four or five. White. 29-33 mm. by 23-25. 
Breeding-season. August to November (but varies according to the rains in different parts). 
It is rather difficult to deal coherently with this species, as I here consider 
as one species a series of birds which have been separated into two distinct 
species, also including a recently described third species. 
The earliest described form came from Port Lincoln, South Australia, 
and this received two names : the description not being perfect, this form 
was re-described from almost the type-locality and again two names were 
bestowed upon it. From King George’s Sound a different-looking bird was 
described later, and these two have been commonly regarded as distinct species. 
The discrimination of the forms belongs more exactly to the technical portion 
of this article, so I propose to deal with what is known of the habits first, 
keeping as close as possible to the geographical ranges of the forms.
