112 THE AUSTRAL AVIAN RECORD [Vol. IV. 



nigra Gmelin, also proposed for a Black Oystercatcher from 

 America. 



Acanthiza ewingii Gould and 



Acanthiza flaviventris Ashby 

 are omitted. Full details will be given in Mathews's Birds 

 of Australia. 



Leucocirca leucophrys (Latham 1801) 



Black and White Fantail 

 The reason for this alteration will also be found in Mathews's 

 Birds of Australia, the part deahng with this species being 

 now in the printer's hands. 



Heteractitis brevipes Vieillot 1816 

 Grey-rumped Tattler 

 We are agreed this is quite a distinct species from H. incanus 

 Gmelin, and therefore reinstate it as above. 



Dacelo novceguinece (Herrman 1783, Alcedo) 

 Kookaburra 

 This is an unfortunate change, necessitated through the 

 acceptance of Herrman's work as appearing earlier than that 

 of Boddaert. 



Oreoica gutturalis (Vigors and Horsfield 1827) 

 Crested Bell Bird 

 This name must be reverted to, as Lewin was anticipated 

 in his choice of Turdus cristatus by Pennant twenty years 

 before. 



Since the above was drawn up, the Auk for July 1920 has 

 been received, including the Seventeenth Supplement to the 

 American Check List, which shows a number of changes of 

 nomenclature still further drawing together towards uniformity 

 the names of the birds of the world. Therein is accepted 

 the usage of Catharacta, Hydroprogne, Thalasseus, Chlido- 

 nias, Pterodroma, Casmerodius, Crocethia, Tringa, Pluvialis, 

 Charadrius, Tyto as proposed in Mathews's Check List, and 

 all, save Hydi^oprogne and Thalasseus, which are ranked as 

 subgeneric only, with the same status. They also accept 

 Sula dactylatra for the Masked Gannet.
