[Plate I.] 1 HE Maltese Islands run from north-west to south-east; their long axis, including the intermediate channels, does not exceed twenty-nine miles. Malta, the most southern of the chain, is seventeen miles long by nine miles broad. Comino is two miles long by one in breadth ; and Gozo, the most northern, is nine miles in length, with a breadth of about five miles. All the islands belong to one series, and, according to the latest re-searches, are to be considered portions of an early Miocene equi-valent to the Hempstead beds in England *, and of the middle Tertiaries of the south of France, north of Italy, Doberg bei ,Bunde in Westphalia, and the Urchin-beds of Bonifacio and elsewhere in Corsica f. The formations are sedimentary and marine, with a horizontal stratification, and are all conformable. The greatest thickness of the deposits equals nearly 800 feet above the sea-level. The * Prof. E.
