The presence of Zieten's type-specimen of Ammonites calcar in the British Museum (Natural History) among some fossils which were bought of Dr. Bruckmann naturally suggested an examination of the other fossil Cephalopoda obtained from the same source, in the hope of finding other type-specimens. Thus far, the result of this examination has been the discovery of two more of Zieten's types; these are the type-specimens of (i) Ammonites polygonius and (ii) Ammonites discoides.

In May, 1897, a fossil tortoise was found about 10 feet above low water-mark opposite Shepherd's Chine, by Mr. Wm. White, of Atherfield, Isle of Wight. It came into my possession in July of last year (1899). At that time the only portions clear of matrix were the sixth, seventh, and eighth costal bones, the edges of the marginals, and the epi- and hyoplastrals nearly to the notch ; the matrix is a fine silt containing much iron. The specimen had been subjected to long attrition by the sea. A very thin but hard seam of whole and broken Paludina had offered a stubborn resistance, as likewise it did against a finely pointed and tempered chisel. On the surface of the carapace are several Cyprids (sp. ?) and the impression in section of Paludina.

In a former number of this Magazine, and also in a Report published by the Geological Survey of Canada, I showed reasons for believing that while the land around Hudson Bay, in the northern part of Canada, had undoubtedly risen several hundred feet in Post-Glacial times, it has now reached a condition of stability similar to that of the land along the Gulf of St. Lawrence and on the eastern seaboard of Canada.

I have received a copy of the paper by Messrs. Harrison and Jukes-Browne on the Oceanic Deposits of Trinidad, and wish to place on record a few remarks on it.
