Two or three species of this shell were presented to the Museum by Mr. Hunter, the surgeon to the expedition; it is proved to be very distinct from J. fragilis, from the description of its float by Dr. Coates in the transactions of the Society of Natural Science of Philadelphia.

Captain King brought home several minute species of Nautilus, which will be taken notice of at a future period, as they require particular examination and minute comparison with those found upon the coasts of Italy and other parts of Europe.

A FEW GENERAL REMARKS ON THE VEGETATION OF CERTAIN COASTS OF TERRA AUSTRALIS, AND MORE ESPECIALLY OF ITS NORTH-WESTERN SHORES. BY MR. ALLAN CUNNINGHAM, COLLECTOR TO THE ROYAL GARDENS AT KEW. It having been resolved by the British Government to employ a colonial vessel from the settlement of Port Jackson in New South Wales, for the purpose of exploring the whole of the North-western Coasts of New Holland, and that portion of the North Coast, not seen by that able navigator, the late Captain Flinders; a most favourable opportunity was thereby afforded for a partial examination of the plants of those unknown shores, with a view of adding to our progressively augmenting knowledge of the very interesting Flora of this southern continent.
