species of New-Zealand Birds. 459 



The genus lurnagra was established by Lesson in 1837. 

 Our oldest known species, the Tanagra capensis of Sparrman 

 (1786), and Turdus crassirostris of Gmelin (1788), was made 

 by Mr. Gray in 1840 the type of his genus Keropia [lege Ceropia'] . 

 But in 1841 he referred the species to the genus Tumagra ; and 

 I have deemed it right to follow his determination. The names 

 T. macularia, Quoy & Gaim., and Otagon turdus, Bonaparte, 

 also refer to our well-known bird the Piopio of the South Island. 

 Prof. Schlegel retains Bonaparte's genus Otagon, and adopts the 

 rejected generic title of Tanagra specifically to distinguish the 

 new form. Following our nomenclature, this will become Tur- 

 nagratanagra, which appears to me an objectionable association 

 of names. 



The merit, however, of being the first to notice the existence 

 of this new species belongs to Prof. Schlegel, although he was 

 apparently unaware that it came from New Zealand. 



Anas gibberifrons, S, Miiller. 



I am indebted to Dr. Finsch for setting me right with respect 

 to this species. It is remarkable, however, that a bird known 

 to inhabit Australia, and having so wide a geographical dis- 

 tribution, should have been entirely omitted from Mr. Gould's 

 recent ' Handbook to the Birds of Australia.' Although my A. 

 gracilis now sinks into a synonym, I feel quite as much satisfac- 

 tion in having added A. gibberifrons to the list of New-Zealand 

 species. 



While on the subject of Ducks, I would add that a further 

 addition has been made to our avifauna in an example sent to 

 me by Captain Hutton, which I have identified as the Nyroca 

 australis of Gould. Several specimens were obtained by Captain 

 Hutton from Lake Whangape, in the Province of Auckland 

 \yide supra, 395] . 



PODICEPS CRISTATUS (Liuu.) . 



The specimen from which [ took the original description of 

 my P. hectori did not present any white markings on the wings 

 or scapulars ; but this was probably due to the condition of the 

 dried skin ; for in all the specimens I have since examined, this 

 character is sufficiently conspicuous. My supposed species.
