26. Gerygone albofrontata. 
Not common, but found in all the islands. It has very much the habits 
of the New Zealand species. 
29. Petroica dieffenbachii. 
Not common, but found in all the islands, but I doubt the propriety of 
separating this bird from Petroica macrocephala. 
—. Petroica traversii, sp. n., Hutton. 
I only found this bird at Mangare, where it is not uncommon. Tt is very 
fearless, possessing in other respects the habits of Petroica albifrons and 
P. longipes. Its ordinary note is also the same, but I did not hear it sing. 
It appears to be specially obnoxious to Anthornis melanocephala, which always 
attacks it most savagely when they meet. There is no apparent difference in 
the plumage of the sexes. : 
33. Anthus nove-zealandie. 
38. Rhipidura flabellifera. 
48. Platycercus nove-zealandic. 
These birds are not uncommon in all the islands, and exhibit precisely the 
same habits as in New Zealand. 
49. Platycercu# auriceps. 
I never found this bird on the main island, but it is numerous on the 
other islands. I was often for some time surprised at finding the bodies of 
dead birds which I had thrown away partially eaten, and could not account 
for the fact until I found this bird feeding on them. This is also a habit of 
Nestor meridionalis. In other respects the habits of this bird are the same as 
in New Zealand. I obtained a specimen on Mangare, with a faint yellow. 
tinge on the head. 
—. Chrysococcyx plagosus. 
This bird is nearly, if not absolutely, identical with the Australian species. 
Tt appears on the islands in the month of September, and leaves towards the 
end of January. If this bird visits the Chathams from Australia it is 
remarkable (as Capt. Hutton has observed) that it must pass over the large 
islands of New Zealand and extend its flight an additional 450 miles. 
56. Carpophaga nove-zealandie. - 
-~ Now common on all the islands, and abundant on Mangare, where it 
breeds. It is said to have made its first appearance on the islands about 
1855. Eggs whitish, spotted with brownish-pink on the larger end. Length 
_ 1-47 in., diameter 1-07 in.
