Show 1876.] MR. P. L. SCLATER ON BIRDS FROM ST. LTJCIA. 13 Ziphius australis ; nevertheless the row of teeth standing above the gums was perfectly formed ; and, secondly, the specimen of Ziphius novce zealandice, of which the Canterbury Museum pos-sessses a complete skeleton, was an aged female and obtained in the flesh, but did not show the least trace of any row of small teeth above the gums. 1 have examined carefully the gums of the new species in both jaws, where no teeth were visible, but without the least success, no hidden teeth being in existence anywhere. Finally I propose to designate this new Cetacean by the specific name oi grayi in memory of the late Dr. J. E. Gray, to whom New Zealand is so much indebted for his contributions towards the better knowledge of its natural history. Conclusion. In summing up the evidence which the three skulls under review present to us, the following points may be accepted as fully established :- 1st. That there exists a Ziphioid Whale ip the New-Zealand seas which possesses a mandibular tooth at the posterior edge of the symphysis, either hidden below the gum or standing conspicuously above it, according to age or sex. 2nd. That the skull of one of the sexes (probably the female) is longer,but narrower and lower than that of the opposite (probably the male) sex-the latter possessing also a large triangular compressed tooth rising above the gum, which in the other (probably female) sex is much smaller and almost hidden below the gum. 3rd. That both sexes possess permanently in the upper jaw a row of small conical teeth with the apex slightly incurved, which, although only rooted in the gums, have to perform important functions in the nourishing-process of the animal. 3. O n some additional Species of Birds from St. Lucia, West Indies. By P. L. S C L A T E R , M.A., Ph.D., F.R.S., Secretary to the Society. [Received November 30, 1875.] (Plate II.) The Rev. J. E. Semper, of St. Lucia, who has already done so much to make us acquainted with the ornithology of that island, has lately forwarded to me a third collection of birds, which I have now the pleasure of exhibiting. It contains examples of eight species not included in m y two former articles on this subject*, and among them two specimens of a very remarkable form, which * P. Z.
