Occurrence of recent Shells in the fossil state near Melbourne. 113 sides with an inconspicuous tubercle. Elytra oblong, shoulders prominent, but the apex of the cone largely truncated, with the posterior edge of the truncature projecting; surface coarsely punctured, blackish, streaked with reddish tawny, behind the middle tawny streaked with black, the tawny part separated from the anterior darker portion by a pale-ochreous fascia. Body beneath tawny, middle of abdomen black. Legs tawny, sprinkled with black, base of claw-joint reddish. Para. [To be continued.] XL — On the Occurrence of Limopsis Belcheri, Corbula sulcata, and some other recent Shells in the fossil state in Miocene Tertiary Beds near Melbourne. By Frederick M'Coy, Pro-fessor of Natural Science in the University of Melbourne, and Director of the Melbourne National Museum, &c. Having occupied myself lately, in my capacity of Palaeontologist to the Geological Survey of Victoria, with the investigation of the Tertiary fossils collected by the Survey Staff from the strata of Bird-Rock Bluff, near the mouth of Spring Creek, about fifteen miles south of Geelong, I was much struck with the geographical distribution of the very few recent species found associated with the large majority of extinct species in a rich fossil fauna unmistakeably of the Lower Miocene age. The whole facies of the fossil contents of these beds resembles closely that of the Lower Miocene beds of Doberg (near Biinde, West-phalia), Malta, and some other European beds of the same age, as well as the so-called Upper Eocene North-American beds near Vicksburg on the Mississippi ; and many of the genera, as well as the great majority of the species, are extinct. Amongst the extinct genera of shells, Aturia amongst the Nautili may be mentioned as conspicuous; and amongst Fishes, Carcharodon may be mentioned as an abundant Upper Eocene and Miocene genus of Sharks, not more than one species of which is found in our present seas, represented by the two best-known and most widely distributed Eocene and Miocene species found abundantly in such strata in England, Germany, and other parts of continental Europe, and in North America, namely, the Carcharodon megalodon (Ag.), specimens of which occur in our Spring-Creek beds (though not very commonly) perfectly iden-tical with those from Malta or England, or the supposed Eocene beds of South Carolina, or the Miocene beds of Virginia and Maiyland, — and the Carcharodon angustidens (Ag.), which occurs abundantly in our Austrahau beds so perfectly identical with specimens from the Lower Miocene of Doberg near Biinde, that.
