to January, 1917. The trips will be memorable for the re-discovery 

 of Quoy and Gaimard's two long-lost species, Malurus leucopterus 

 and Amytornis textilis, and the discovery of several new sub-species. 

 These are dealt with in my critical remarks which follow. Mr. 

 Carter's field-notes are of a high order, after the style of his 

 " Birds Occurring in the Region of the North-West Cape" (four 

 parts), which appeared in The Emu, 1903, vol. iii. 



[Nomenclature according to the R.A.O.U. "Check-list" and 

 Mathews's " List of the Birds of Australia " ; colours after 

 Ridgway's " Standards."] 



Zonifer pectoralis, Cuvier. Black-breasted Plover. 

 Z. tricolor givendolence . 



Two $? from Dirk Hartog. Regarding this widely-distributed 

 endemic Plover, Mr. Mathews claims that there is a south-western 

 race which possesses a " different-shaped (larger) wattle and 

 narrower black band on breast " than the eastern bird, and gives 

 a figure in his " Birds of Australia," iii., pi. 131. The bird is 

 named in honour of Amy Gwendoline Carter, daughter of Mr. 

 Thomas Carter, M.B.O.U., who has spent a lifetime amongst the 

 birds of Western Australia and discovered many new species. 



Mr. Carter observed this species on Dirk Hartog Island on 

 several occasions, but did not obtain examples. The two birds 

 that Mr. Whitlock secured have general coloration of the back 

 huffy-brown, nearer the hue of typical eastern birds, while the 

 dimensions (mm.) — length 285, wing 195, tarsus 48, culmen 25 — 

 are practically those given for gwendolencB. 



Geopelia humeralis, Temminck. Barred-shouldered Dove. 



CJirysauch(ciia humeralis headlandi. 



Two 00, Barrow Island. Whitlock calls these " Mangrove- 

 Doves." They are decidedly smaller in size and paler-coloured 

 than typical birds from the East. Mathews's headlandi will 

 distinguish the Western race. 



Cerchneis (cenchroides) unicolor, Milligan. Western Kestrel. 



One 0*, I $, Barrow Island. The male resembles unicolor 

 (Milligan) ; the female resembles milligani (Mathews). 



Cacatua (sanguinea) gymnopis, Sclater. Bare-eyed Cockatoo. 

 Ducorpsius sanguineus westralensis. 



Two ??, Dampier Group. With more material and the 

 examination of a larger series it is necessary to add to my former 

 note {Emu, ante, p. 7). When I stated that the island bird was 

 " whiter " I meant " less soiled " than was the plumage of north- 

 west mainland specimens. The whitest (pure white) birds are 

 from the Northern Territory. If Gould's sanguinea be from 

 Port Essington, Mathews can hardly hope to sustain his distinctus 

 from Alligator Creek, practically the Port Essington region 

 (Arnhem Land). 



A large series of this Cockatoo from Arnhem Land in the 

 National Museum, Melbourne, shows that the general plumage
