We have felt much hesitation in describing 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 Nove 
Zaælandiæ*, which species has been ascertained to belong to the 
2; Australian Fauna. But it does not so well accord with M. Tem- 
minck's figures of that speciest, 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, uñtil more perfect specimens permit us to peak with 
certainty. — | im Hire

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