138 THE AUSTRAL AVIAN RECORD [Vol. III. 



Here is a good example of the discrimination 7 necessary- 

 be tween representative species and subspecies, as here are seen 

 three species which are not yet known to inhabit the same 

 districts, but cover the whole of Australian coastal districts, 

 as they are not birds of the interior. 



Birds from Coomooboolaroo, Queensland, were considered 

 to belong to melanura by Campbell, but the females in my 

 possession prove them to belong to the form of pectoralis I 

 have called ashbyi. 



The Kangaroo Island bird is now regarded as inseparable 

 from the mainland South Australian form. 



This short note is not intended to be exhaustive, as I will 

 so treat the species in my big work. 



While looking up the above matter I noticed that Gould 

 determined his own Pachycephalia inomata as the immature 

 of P. gilberiii. As it had priority and was being used in a 

 different sense, I re-examined specimens in conjunction with 

 the 1 descriptions, and must agree with Gould's conclusion. 

 Consequently the species name must be altered, and we will 

 have 



Gilbertornis inornalus inornatus (Gould). 



South Australia. 

 Gilbertornis inornatus gilbertii (Gould). 

 West Australia.
