The skull was larger in proportion to the body than in either Dinornis maximus or D. mgeiis, but manifested no modification approaching to the shape of the bill in Apteryx; it retained the generic characters shown in all the larger kinds of Dinornis. The sternum was strictly Dmormthic. The chief osteological distinction was a greater number of cervical vertebra? ; but the author remarked that no other skeleton had been discovered, or recovered from swamp-deposits, under circumstances precluding the oversight of two or more vertebras from the middle of the long neck, where missing ones might be indicated by size or by joints. The metatarsus gave no indication of an articular surface for a back toe, yet the bones of this minute digit of both feet were transmitted; hence the amalgamation of Palapteryx with Dinornis received additional support. The size of the bird was about that of the Dodo. O n the grounds detailed in the memoir the author referred its subject to the genus Dinornis, and to a new species proposed to be called D. parvus. In the remote, well-wooded, and sparsely populated district of the southern division of N e w Zealand, Prof. O w e n was of opinion that a recovery of a still-existing specimen might be less unlikely than that of the Notornis, also originally recognized by fossil remains.
