No. 1.] THE AUSTRAL AVIAN RECORD 9 



other than refer all these Austral-Malayan species to 

 Chrysococcyx. 



The genus Eudynamys I use for the Koel as almost 

 universally admitted, but I am not sure as to its having 

 priority over Dynamene. I am now working up this 

 matter, and so far everything points to the latter being 

 the correct name. The Tahitian Longtailed Cuckoo 

 E. taitensis (Sparrman) has been placed in a genus 

 Urodynamis by Salvadori (Orn. Papuasia e Mol., 

 Vol. I., p. 370, 1880), but as this is admittedly only a 

 colour-genus, I do not accept it. This bird is included 

 in the Australian avifauna through its occurrence on 

 Lord Howe and Norfolk Islands. 



To treat now of the forms of Cuckoos inhabiting 

 Australia in the order in which they appear in my 

 Handlist : 



Page 57. Species 404 is there called Cuculus saturatus 

 Hodgson, which name was used to replace Cuculus 

 intermedius Vahl. of the Cat. Birds Brit. Mus., Vol. 

 XIX., p. 252. The races of Cuculus canorus Linne are 

 difficult to determine, and as the material at my disposal 

 does not warrant me in still accepting C. saturatus, from 

 a study of the original description, I am reverting to 

 the name proposed hy Gould, C. optatus. A name, 

 given by S. Muller, C. canoroides, may be applicable, 

 but in the present uncertain state of the nomenclature 

 of the species, I am using the name certainly available 

 as it was given to the Australian form. Dr. Hartert 

 is now working upon these puzzling birds for his Vogel 

 der palaarktischen Fauna, and when the results of 

 his studies are published I shall be able to make a more 

 positive decision. I am tentatively referring to the 

 Australian form as Cuculus canorus optatus Gould. In 

 the Proc. Linn. Soc. N.S.W., Vol. II., p. 205, 1876, 

 Ramsay notes that Diggles had described a Cuculus 

 brisbanensis which from the description he identified 

 as the young of Cuculus optatus Gould = C. canoroides 

 Muller. The original description by Diggles I have 

 been unable to trace, and I would be glad if anyone,
