Art. XXIII.—A List of Recent and Fossil Bryozoa collected in various Parts of New Zealand. By A. Hamilton. [Read before the Otago Institute, 12th October, 1897.] In 1880, when living at Petane, near Napier, I commenced a correspondence with Miss E. C. Jelly, who was then residing at Bristol, on the subject of our New Zealand Bryozoa, and from that time until quite recently I have been forwarding parcels of recent and fossil species from different parts of New Zealand. Miss Jelly has long been known as an enthusiastic student of the Bryozoa, and as one whose intimate acquaintance with the literature of the subject gives authority to the excellent synomymic catalogue of the recent marine Bryozoa, published by her in 1889. Through Miss Jelly the specimens I collected have been passed on to the principal authorities on the various groups, and several of the new species have been described in English scientific publications, and others are still awaiting description. Many species still living have been obtained as fossils from the upper beds of the Wanganui series typically exposed at Petane and Napier; and many of these are also found in the Tertiary beds of Australia. Whenever deep-sea dredgings are undertaken in the deeper waters of the New Zealand coast we may expect a considerable addition to the rarer genera. The localities from which the specimens have been forwarded are:— 1. Napier.—The species under this heading are either from the littoral of the harbour, from the old dead shells thrown up by storm on the beach, or from adjacent parts of the Hawke's Bay coast. The fossil species are from the Napier limestone, a local formation included in the lower beds of the Wanganui series of the geological survey. 2. Wanganui.—Some of the species under this head are from the typical locality, Shakespeare's Cliff, Wanganui, others from the corresponding blue clays and sands on the Hawke's Bay side of the Island. 3. Wellington.—These are all recent species, collected at various times on the shores of Cook Strait. 4. Dunedin.—These are also littoral species collected at various times. 5. Foveaux Strait.—The oyster-beds of the strait between Stewart Island and the South Island of New Zealand afford a very large number of excellent specimens of Bryozoa, and by examining the oyster-shells and a little dredging many species have been obtained.
