Nos. 4 & 5.j THE AUSTRAL AVIAN RECORD 113 



The matters at variance are as follows : Moris is used for 

 the Gannet which is considered separable from Sula, and they 

 do not admit that Moris is the same as Morus. Forster used 

 this name following Leach, whom they quote as if a valid 

 pubhcation, and in spite of the Opinions of the International 

 Commission, and Moris is apparently simply a printer's error 

 for Morus. In Leach's MSS. in the British Museum the 

 abnormal number of printer's errors is remarkable, and in 

 Forster's Catalogue we can read Odogometra, Octygometra and 

 Ortygometra, as well as others. Such a matter as this should 

 have been considered with all the facts in view. 



Crocethia alba (Pallas) is preferred to Crocethia leucophma 

 (Pallas), both specific names being published in Vroeg's 

 Catalogue, and this matter requires reconsideration before 

 final settlement, but we use C. alba for uniformity. 



They have rejected Heteractitis in favour of Heteroscelus, 

 which they determine to be valid, although there is a prior 

 Heteroscelis, which is absolutely the same word and simply 

 shows an error in transliteration which is amenable to 

 emendation according to the Opinions of the International 

 Commission. 



They have rejected the Oken names and also those of 

 Lepechin, and moreover are not acknowledging those proposed 

 by binary authors save those by Brisson. In these items 

 we are in accord and soon there will be absolute unanimity, 

 the one bar at present being their reluctance to admit the 

 British usage of Colymbus for the Divers, but this seems 

 merely a matter of adjustment in the near future. A few 

 other items wliich do not concern Australians are cleared up, 

 but in the Swan names they show again a reluctance to correct 

 an error as the type of Cygnus, whether of Zimmermann or 

 Bechstein, by tautonymy, is Anas cygnus L. and consequently 

 Olor cannot be maintained. 



We are gratified to be able to record so much advancement, 

 and there can be little discussion on the subject of nomen- 

 clature for many years now, errors being corrected as soon 

 as they are detected, and attention paid to systematic 

 classification, morphology, ecology and economy.
