Tue present species of Aerula appears to have been known for a much longer period than T had supposed ; 
indeed I was not aware that Latham had given a good description of the bird under the name of Zurdus 
poliocephalus, otherwise I should not have proposed the additional name of Nestor. When Norfolk Island was 
first made a penal settlement, this bird was doubtless very common there ; but I have reason to believe it has 
now become scarce, having been partially extirpated by the Government officers and convicts who tenanted 
this beautiful island for so many years. Some short time since, I described a second species of this form 
from Lord Howe’s Island, under the name of Merula vinitincta; and I have seen a third species in the British 
Museum (Merula wanthopus ?, Turdus aurantius, var. B Ginel.), which I believe is from New Caledonia. All 
these have a general resemblance both as to form and style of colouring ; and it would be as well perhaps if 
they were formed into a new genus among the Meruline, for 1 have always considered them somewhat 
removed from the true Blackbirds of Northern Asia and Europe. I have long wished to know something 
of the habits and economy of these birds, but at present nothing has been ascertained : there appears to be 
less difference in the colouring of the sexes than occurs among the true Merwe ; for the birds I consider to 
be females are very similarly coloured, and are only a trifle less in size. 
Head, neck, and front of the throat light ashy brown, the remainder of the plumage dark sooty black ; in 
some specimens the under tail-coverts have a stripe of dull white down the centre of each; bill, eyelash and 
feet yellow. 
The figures are of the natural size.
