34 MAMMALS OF THE PACIFIC WORLD 



The Hare Wallabies {Lagostrophus, Lagorchestes), the 

 smallest of the wallabies, are so named for their hare-like speed 

 and their habits of crouching close and solitary on "forms," 

 like hares. The banded hare wallaby (Lagostrophus), known 

 only in Western Australia, is conspicuously patterned with 

 transverse blackish marks across the back on a ground of 

 brownish gray. The remaining species of hare wallabies (La- 

 gorchestes) have dark backs and a wash of red on the outside 

 of the thighs (whitish in L. conspicillatus, which has also a 

 reddish patch around each eye). 



The Tree Kangaroos (Dendrolagus) are a specialized oif- 

 shoot of the kangaroos and wallabies, whose legs, still of leap- 

 ing type, have nevertheless become shorter and more massive. 

 The foot pads are granular ; they assist in climbing. Six quite 

 distinct species with several geographical races are known, four 

 from New Guinea and two from Australia. 



Tree kangaroos reach a total length of four feet approxi- 

 mately, of which the tail equals about half. All are agile climb- 

 ers and some can make downward leaps of thirty feet with re- 

 markable sureness. 



Matschie's Tree Kangaroo (D. matschiei), with bright 

 golden chestnut upperparts and golden yellow tail, appears 

 restricted to northern New Guinea. A close relative (D. good- 

 fellowi) with dark bands on the tail, inhabits the slopes of the 

 central ranges of New Guinea. 



Doria's Tree Kangaroo (D. dorianus) is grayish brown, with 

 a yellow-brown patch on the rump, at the base of the tail. It 

 lives in the central ranges of New Guinea. 



The "Bear-like" Tree Kangaroo (D. ursinus) is a brownish 

 black species, with the hair tips occasionally frosted with white. 

 It is found only in western New Guinea. 



The Grizzled Tree Kangaroo (D. inustus) is brownish gray 

 with the hair tips heavily grizzled ; the tail is sometimes nearly 

 all white. It is found only in the western half of New Guinea.
