Art. II.—An Exhibition of New and Interesting Forms of New Zealand Birds, with Remarks thereon. By Sir Walter L. Buller, K.C.M.G., F.R.S. [Read before the Wellington Philosophical Society, 29th October, 1890.] Probably no section of New Zealand zoology has received such careful attention or been so thoroughly worked as the birds. Their beauty of form and colour, and the peculiar interest attaching to their life-history—their natural habits, their song, their wonderful modes of nidification—and their general ministration to the requirements and caprices of man, all tend to make the study of our birds more attractive than that of any other branch of natural history. So much has already been written on this subject that it might reasonably be looked upon as a well-nigh exhausted field. So far, however, from this being the case, new forms and characters of bird-life, and new facts in the history of even our commonest species, are being continually brought to light; and it seems
