D. ursinus. New Guinea.

These animals ascend trees, and are distinguished by their powerful fore-limbs and long pliable tail, which resembles that of the Rock-Wallabies. A third species, Dorcopsis Bruni, also inhabits New Guinea, but is terrestrial, though the fore-legs are more strongly developed than is usual in Kangaroos. The weight of these animals we should judge to be about 30 lbs. The D. Bruni was the first Kangaroo ever discovered, many years before Cook's voyages.

Silky-haired or Nail-tail Kangaroos.
