from Western Australia. 181 
Dr. Gadow was right in joining this species to the eastern 
M. lunulatus. 
From personal observation and from my collection of skins 
I conclude that there is a western representative of M. lunu- 
latus, so we may now separate the two forms joined in the 
British Museum Catalogue. Besides this a difficulty presents 
itself if we wish to refer my skins to the species M. chloropsis, 
because, I take it, Gould has insufficiently described the 
eye-region of the bird, and that part is incorrectly coloured 
in his plate. I do not care to regard my skins as giving 
evidence of a new species, because 1 believe that Gould has 
described two phases ; besides which there is a third, hitherto 
unnoticedr — and that the most adult, as the naked spaces 
surrounding the eye are large. More extended research may 
shew that (a) the pale green of the bare space above the eye 
changes into (b) a pale wine-yellow, and at a later season 
into (c) a sappy white. Furthermore, at this later season 
it may be shown .that a bare space becomes prominent below 
the eye, and that there is a hidden bare region at the 
posterior angle, the former being leaden blue and the latter 
faint blue-green. No reference has been hitherto made to 
the bare spaces below and behind the eye : {a) and [b) are 
the parts as described by Go aid, while (c) represents the 
appearance in three skins collected by myself, and in at least 
six others closely and carefully noted and found to possess 
the same distinct marks. Since the eastern M. lunulatus 
varies in the colour of its eye-region with age (this is how I 
view the shades of red), the western form may for the present 
be assumed to do likewise, but apparently to a greater extent. 
Future research may show more points of interest in this 
connexion. 
Description of these parts in the specimens secured by the 
writer : — Bare space above the eye dull sappy- or fungus- 
white. Bare space below the eye, which is quite as large, 
dull lead-blue in colour. Hinder angle of both bare parts 
that are hidden by the imbricate feathers faint blue-green. 
Iris bright hazel, with a tendency to red.
