burnt off, afforded ample evidence that it had once been a favourite habitat of the Bulimus antipodarum. A smaller shell, which he was inclined to set down as the young of the Bulimus antipodarum, or an Achatina, had been obtained from the natives. None of the larger Bulimus antipodarum had been found at Bream Head, though abundance of the smaller kind were met with. However, he had some doubt of the identity of the Whangarei with the Bream Head species. On Mania hill, near Whangarei, he had found what at first sight appeared to be three varieties of a whorled shell, like a Turritella, but which he supposed to be a Cyclostoma. The larger variety had six whorls, about half an inch long, by one-eighth of an inch in width; and of a brownish colour, indistinctly striped: the mouth being nearly circular, and much contorted to the right, with a sort of double lip all round. The smaller variety, five whorls, a quarter of an inch to three-eighths of an inch long, had not the contorted mouth, nor the double lip. The smaller variety was only ten-twelfths of an inch in length, by 7 in. wide. He had also obtained a large number of Helices, amongst which he could distinguish the Helix Busbyi, and the Helix Dunniæ. Mr. Gillies went on to exhibit and to describe shells, which he had obtained at the Waitangi Falls, and in the Northern streams.

Captain Hutton said Mr. Gillies deserved the thanks of the members of the Institute, for the valuable services he had rendered to the geology of New Zealand.
