XL. — Note on the Nestling Plumage of Gypoictinia melano- 

 sternon {Gould). By John Henry Gurney. 



In 'The Ibis/ 1884, at p. 465^ will be found some particulars 

 respecting that very rare Raptorial bird Gypoictinia melatio- 

 sternon, which were communicated to me by Mr. K. H. 

 Bennett. 



The Norwich Museum has recently received from this 

 gentleman a fledged nestling of this species, taken from the 

 nest near Mossgiel, in New South Wales, on the 6th of 

 December, and supposed by Mr. Bennett to be " between two 

 and three months old." 



The following is a description of this specimen, which I 

 am desirous of recording, as, so far as I am aware, no account 

 has previously been given of the first plumage of this species.
