Owen could not determine any specific distinction in the present fossil from the 
Hyena neogea or ‘ Smilodon” of Dr. Lund, he proposed to call the species “‘ Ma- 
chairodus neogeus.” This, happily extinct, most formidable and destructive of the 
carnivorous genera, had anciently an extensive geographical range through a great 
extent of South America, in India, and throughout Europe; fossil remains of differ- 
ent species having been found in old pleiocene deposits in Germany and France, in 
the newer pleiocene of the Val d’Arno, and in the bone-caves of England. Our 
* Own ancient Machairodus latidens of Devonshire, added to the other species, con- 
firms the propriety of keeping the genus distinct from the typical Felis. 
Of the gigantic extinct Armadilloes, Prof. Owen added to the former species, which 
he had called Glyptodon clavipes, the following, viz. Glyptodon reticulatus, Glyptodon 
ornatus, Glyptodon tuberculatus, and Glyptodon clavicaudatus. An enormous tail of 
_ the latter, now in the British Museum, showed several of the ossicles of the dermos 
_ skeletal sheath produced into huge tubercles, the whole resembling the club of the 
_ giant Gog or Magog. Prof. Owen thought that the present knowledge of the co-exist- 
_ ence with those large herbivorous Armadilloes of a gigantic carnivorous species like 
Machairodus, gave some insight into their need of a complete and strong defence of 
all the exposed parts of the body and the tail, since they had not the powerful claws 
with which the Megatherioid quadrupeds might have waged war with the Machai- 
_ rodus. With regard to the Megatherium, the remains recently transmitted confirmed 
_ Prof. Owen’s ideas of its closer affinity to the Sloths than to the Ant-eaters or Arma- 
_ dilloes; and had enabled him completely to reconstruct both the fore and hind ex- 
 tremities, and correct some errors in Cuvier’s descriptions. 
¥ Mr. Edwards communicated a list of the fossils of Bracklestone Bay, Sussex. Of 
_ the classes Conchifera, Brachiopoda, and Gasteropoda, there are 161 described spe- 
cies, and seventy-nine undescribed; seventy-four of which are also found at Bar- 
_ ton. Of the 161 described species, 106 are identified with French and fifty-five with 
_ English species. Respecting Foraminifera, Corals, and Cephalopoda, the author 
_ states that they are under examination. 
Notice of some Tertiary Rocks in the Islands stretching from Java to Timor. 
By J.B. Juxes, M.A., F.G.S. 
Behind the town of Coupang, in the island of Timor, the land rises in gently 
sloping hills to the height of 500 or 600 feet, the nature of which is exposed in a 
_ Narrow precipitous valley. These cliffs and the shore itself are composed of a very 
_ Fecent tertiary formation, which appears to be a raised coral reef, abounding in 
_ Astrea, Meandrina and Porites, with shells of Strombus, Conus, Nerita, Arca, Pec« 
_ ten, Venus and Lucina. On a ledge about 150 feet above the sea, Mr. Jukes found 
_ a Tridacna two feet across, bedded in the rock, with closed valves, just as he had 
often seen them in the barrier reefs. The thickness of this formation was proba- 
' bly several hundred feet; and it seemed to spread far and wide over the country, 
| wrapping round the central mountains, which were lofty, and probably volcanic, 
_ peaks. Samou Island appeared to be wholly composed of this rock, often forming 
| precipices 200 or 300 feet in height. Sandalwood Island presents a lofty coast of 
cliffs and hills, rising 2000 feet above the sea, and attaining a still greater elevation 
inland. All the coast cliffs were regularly stratified in thick horizontal beds ; white 
when fresh broken, but weathering nearly black. The cliffs and precipices of Sum- 
bawa are equally lofty, and exhibit the same regular bedding. The island of Lom- 
bock slopes gradually from its southern shore to a great conical volcanic mass, 
11,400 feet high, which towers from its north-east corner. The southern coast- 
Cliffs, about 200 feet high, were composed of a white, horizontally-stratified rock, 
~ covered by a considerable thickness of brown and yellow thin-bedded rocks. The 
island of Madura was found to be composed of the same white, chalk-like strata ; 
this island rises in one or two terraces into slightly undulating plains, with groups
