In the present note it is intended to record a find of considerable importance to geologists and palaeogeographers, namely the discovery, last summer, by Mr. J. M. Wordie, St. John's College, Cambridge, of Lower Eotriassic ammonites at three localities on the south side of Gael Hamkes Bay, on the East Coast of Greenland, in 74° N. latitude. There are altogether ninety-five specimens, most of them well preserved, including various new forms, of which I hope to publish full descriptions elsewhere.
