THE BIRDS OE AUSTR A LI A. 
took place from the east, as there are no relations of either in the north-west, 
yet a closely allied species at present lives in New Caledonia. 
This species has been very unfortunate in its nomenclature, but I hope the 
present solution will prove more stable than my previous attempts. Gould 
retained his own name in preference to the older name given by Quoy and 
Gaimard, but incorrectly cited the wrong name of those authors in his 
synonymy. In the Catalogue of the Birds in the British Museum this group 
was treated by an incompetent and careless worker, and consequently a 
further confusion appeared by the description of the wrong species under the 
name selected, a futile attempt at correcting Gould’s error being undertaken 
without investigation. North indicated the erroneous “ determinations ” 
and revived the earlier names in their correct application. In my “ Reference 
List,” misled by the confusion of representative species and subspecies, I 
degraded this species to the rank of a subspecies, using Quoy and Gaimard’s 
name, and citing Gould’s as an absolute synonym, at the same time 
proposing a new subspecies as P. a. rosinae, writing : “ Differs from P. a. 
gularis in having the grey band on the throat of a deeper colour and wider ; 
the rump also is not so yellow. Eyre’s Peninsula, South Australia.” 
Shortly afterward I distinguished the Goulclian form as a distinct sub- 
species from the Swan River district, but soon recognised that the western 
forms should be regarded as constituting a distinct species, and accepting 
Pucheran’s identification of Vieillot’s griseicapilla as referable to this species, 
recorded the forms as 
Eopsaltria griseicapilla griseicapilla Vieillot. 
Eopsaltria griseicapilla rosince Mathews. 
Eopsaltria griseicapilla gularis Quoy and Gaimard, 
citing Gould’s griseogularis as a synonym of the first named. 
Mr. Tom Carter wrote me that the type locality of Vieillot’s species 
selected by me as Shark’s Bay was untenable, as the species does not occur 
in that locality. I therefore once more investigated the matter, and found 
that Pucheran’s determination was wrong, and that griseicapilla Vieillot 
referred to the eastern species. I therefore reverted to Quoy and Gaimard’s 
species name and admitted 
Eopsaltria gularis gularis (Quoy and Gaimard). 
Eopsaltria gularis griseogularis Gould. 
Eopsaltria gularis rosince (Mathews). 
Now once again a rearrangement is necessary, as I find that Quoy and 
Gaimard’s name is preoccupied and therefore invalid. The species name will 
become griseogularis Gould, and four subspecies are recognisable :
