The Order presents a remarkable diversity of structure, there being herbiv- orous, carnivorous and insectivorous species, and in fact representatives of many of the higher Orders of Mammals. In the herbivorous species, the canines are usually wanting. Excepting one American and one Ma- layan genus, Marsupials are now confined to Australia, Tasmania and New Guinea. Marsupials were the first of Mammals—the Microlestes having been discovered between the Lias and Keuper Sandstone near Stuttgardt, while the Dromatherium was found in the Triassic (or Liassic) coal-field of North Carolina. No. 181. Diprotodon Anstralis, Owen. Skull and Lower Jaw. This gigantic Kangaroo—nearly equalling the Hippopotamus in size—was discovered in the Pleistocene beds at Darling Downs, Australia, and was therefore contemporary with the great Sloths of South Ameri- ca. Like the Megatherium, while retaining the dental formula of its living ho- mologue, it shows remarkable modifications of its limbs. The hind limbs were shorter and stronger, and the front limbs were longer and stronger than those of living Kangaroos; yet the ulna and radius were so articulated as to give the fore-. paw the rotatory action. The dental formula was i *z\, G % T-T' m i-i=2Sm The front upper incisors were very large and scalpriform, as in the Wombat; the premolars were soon shed; and the molars had two ridges disposed as in the Tapir and Kangaroo, but more compressed and prominent. The D., in this last respect, approached the Pachyderms, furnishing, says Pictet, a new proof of par-.
