26. Gerygone alhofrontata. 



Not common, but found in all the islands. It has very much the habits 

 of the New Zealand species. 



29. Petroica dieffenhacliii. 



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. It is very 

 fearless, possessing in other respects the habits of Petroica alhifrons 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 novce-zealaoidice. 

 38. Rhipidura jiabellifera. 



48. Platycercus novce-zealandice. 



These birds are not uncommon in all the islands, and exhibit precisely the 

 same habits as in New Zealand. 



49. Platycercus 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 ar faint yellow 

 tinge on the head. 



— . Chrysococcyx plagosus. 



This bird is nearly, if not absolutely, identical with the Australian species. 

 It 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 novce-zealandice. 



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.
