Derdrolagus includes four species of Tree-kangaroos, of 

 which, however, only one is found in Australia, Dendrolagus 

 Iv/nihoUzi of Northern Queensland, the others being con- 

 fined to New Guinea. They are remarkable for the fact

that the proportionate lengths of the fore and hind limbs, 

 unlike those of the true kangaroos, resemble those of 

 ordinary mammals; they further differ from all other 

 kangaroos in being arboreal in their habits, climbing trees 

 with great facility, and living on bark, fruits, and leaves.
