This beautiful addition to the ornithology of our country was one of the novelties brought from the Chatham Islands by Mr. Henry Travers on his return from the exploratory visit mentioned on a former page. Professor Hutton had referred it (l. c.) to Graculus africanus (Gmelin), but the original specimen having been courteously forwarded to me by Sir James Hector, through the Colonial Office, I saw at a glance that we had a new species to record, and was therefore glad of the opportunity thus afforded me of describing and figuring it in my former edition.
I had already associated the name of Mr. Henry Travers with one of the new species discovered by him; and, in assigning a distinctive title to this bird, I desired to pay a slight tribute to one who, having originally assisted in founding a colony at the Antipodes, had devoted more than thirty years of his life to its political affairs, and at that time filled the important office of its Agent General in Great Britain—the late Dr. Featherston.
Several further examples have been received at the Colonial Museum, and Mr. Walter Hood informs me that it is a comparatively common bird on the rocks lying off the Chatham Islands, and that he found it breeding there in the months of October and November. On Pitt Island these birds were so tame that he knocked over two of them with a small stone.
As will be at once apparent from the figures, this species bears a general resemblance to P. punctatus: like that bird it has a vertical as well as an occipital crest, and the distribution of the colours is somewhat similar, although the plumage altogether is much darker. It is readily distinguished, however, by its black head and neck, and by the absence of the white stripes which are so conspicuous in the other species.
