distinct maxillo-nasal bone, absence of an antrum or cavity in the maxillo-palatine, and by the strong, coarse character of the bones in general. Dinornis is in some respects even more specialised than Pachyornis, but in an opposite direction: as regards the skeleton generally, it runs to height rather than thickness, and its skull is remarkable for its great breadth and flatness, and for the long, broad, deflected beak. The following phylogenetic diagram gives the views at which I have arrived on this subject:—

Art. II.—On the Presence of a Crest of Feathers in certain Species of Moa. By Professor T. Jeffery Parker, F.R.S. [Read before the Otago Institute, 10th May, 1892.] Plates I.-III. Any evidence as to the external characters of the moa is of interest. We know the general structure of the feathers, and of the thickened and scaly skin covering the feet, but hitherto the only direct evidence as to the appearance of the entire head is furnished by the magnificent specimen of Mesopteryx casuarina (Dinornis didinus, Owen) obtained near Queens-town in 1878, and forwarded to the British Museum in 1882 by Mr. H. L. Squires.* Sir R. Owen states that the discovery of this specimen was first noticed in the “‘Tuatara Times,' published at Otago in November, 1878.” The real name of this paper is the Tuapeka Times. The notice is quoted, as I am informed by Mr. A. Hamilton, in the Otago Daily Times of the 27th November, 1878. The specimen is covered with dried
