Art. III.—New Species of Moas. By Captain F. W. Hutton, F.R.S. [Read before the Philosophical Institute of Canterbury, 2nd November, 1892.] Since I wrote my paper on “The Moas of New Zealand,” which I read to the Institute last year, I have seen Mr. R. Lydekker's valuable Catalogue of the Fossil Birds in the British Museum, and I have also been able to study the whole of the magnificent collection of moa bones in the Canterbury Museum, of which I had formerly seen only a portion. This collection was commenced in 1866 by Sir J. von Haast with bones from Glenmark, and he afterwards added others, principally from Shag Point and Whangarei. Last year, when Mr. H. O. Forbes was curator, he secured the collection found at Enfield, near Oamaru, and gave the greater part of it to the Museum. Mr. A. Hamilton has also contributed a good collection from the Te Aute Swamp; and during this year a small number of bones from Hamilton and other places have been obtained by exchange. I am far from having finished my examination of this collection, but, as it has become my duty to arrange and name it, I think it will be advisable to publish at once the changes to which I have been led in my views on the classification of the moas, as well as to give descriptions of five new species which I think it necessary to make. I have also thought that it would be useful to others if I published the average dimensions of the leg-bones of the moas found at Enfield. There is in the Museum an imperfect skeleton of an individual bird the metatarsus of which is similar to the larger of the two described by Sir R. Owen as D. elephantopus; but the skull has a pointed beak, and the vertebræ are of a dif-
