XXX. — Notes on some Birds from the Chatham Islands, collected 

 by H, H. Travers, Esq, ; with Descriptions of two new 

 Species. By Captain F. W. Hutton, F.G.S. 



Mr. H. Travers having lately returned, with considerable col- 

 lections, from an eight months' visit to the Chatham Islands (a 

 small group lying about 475 miles due east from New Zealand), 

 I am enabled through his kindness to draw up the following 

 list of the birds, which includes not only those species which he 

 brought away, but also a few others of which he was not able to 

 obtain specimens ; so that it may be looked upon as complete, so 

 far as our present knowledge extends. 



1. Circus assimilis, Jard. 



Mr. Travers was unable to procure specimens of this bird ; 

 but he saw a dead one that had been killed too long for pre- 

 serving. He informs me that it does not differ from New-Zealand 

 examples. 



2. Prosthemadera novve-zealandi^ (Gm.). 

 Two specimens. 



3. Anthornis melanocephala, Gray. 

 Several specimens, male, female, and young. 



The female and young diflfer from those of A. melanura only 



in size ; the latter correspond entirely with A. auriocula, Buller. 



The eggs are usually of a darker pink than those of A. mela-
