Postscript to Professor Parker's Paper on the Classification, &., of the Dinornithidæ. Since writing this paper I find that further researches have convinced Professor Hutton that he was not justified in definitely assigning a narrow-beaked skull to Emeus and a broad-beaked skull to Pachyornis. I have therefore come to the conclusion that, for the present at any rate, it will cause least confusion to follow Owen and Lydekker in this matter. Thus, in my forthcoming monograph to be published in the Transactions of the Zoological Society (see abstract in Proceedings Zool. Soc., 14th February, 1893), the large narrow-beaked skull called in the present paper Emeus crassus is named, as by Owen and Lydekker, Pachyornis elephantopus, and the broad-beaked skulls here assigned to Pachyornis are referred to Emeus. Thus the names Emeus and Pachyornis, as used in this paper, must be transposed. I have also found, from a conversation with Professor A. Newton, at Cambridge, that the names I assigned in the present paper to the sub-families are not in accordance with the rules of zoological nomenclature. The classification adopted in my large paper is therefore as follows:— Sub-family a. Dinornithinœ. Genus Dinornis. Sub-family b. Anomalopteryginœ. Genera Pachyornis, Mesopteryx, Anomalopteryx. Sub-family c. Emeinœ. Genus Emeus. April, 1893. Postscript to Professor Parker's Paper on the Presence of a Crest in some of the Moas. During my recent visit to England I have examined the moa-remains in all the principal museums, and have found feather-pits in two specimens of Dinornis robustus—viz., the magnificent individual skeleton from Tiger Hill, Manuherikia, in the Museum of the Philosophical Society, York, and a skeleton from Glenmark Swamp in the Tasmanian Museum, Hobart. The fact that some specimens both of robustus and of ingens (torosus) have the pits, while there is no trace of them in others, certainly points to the crest being a sexual character. April, 1893.
