We have felt much hesitation in describins; this bird as a new 

 species ; the specimen in the Society's collection being in bad 

 condition, and in particular much faded in colour. We con- 

 sidered it to bear much resemblance, as far at least as could be 

 judged from a figure, to the young of Dr. Latham's Falco Novce 

 Zcelandice*, which species has been ascertained to belong to the 

 Australian Fauna. But it does not so Avell accord with M. Tem- 

 minck's figures of that species +, nor with those given in Fors- 

 ter's drawings in the Banksian library]:. We consider it best to 

 record it for the present as a distinct species, with an expression 

 of doubt, until more perfect specimens permit us to speak with 

 certainty. 



The native name of this bird is Mora, and also IVirwin, as we 

 are informed by Mr. Caley. It is called the Jfhistling Hatvk by 

 the settlers. That gentleman adds, that " it makes a loud whist- 

 ling noise when on the wing and sailing about in the air. It 

 frequents the upper parts of the harbour (Port Jackson), par-
