THE DORCA KANGAROOS. GENUS DORCOPSIS. 



Dorcopsis^ Schlegel and Miiller, Verhandl. Nat. Ges. Nederl. 

 Ind., p. 130 (1839-44). 



Hind limbs proportionately less elongated than in Macropus ; 

 naked portion of nose large, broad, and wholly devoid of hair ; 

 head long and narrow ; ears small ; fur on nape of neck, from 

 the back of the head to the withers, directed wholly or partially 

 forwards ; hind claws long and strong, not concealed by hair ; 

 tail evenly haired, and nearly naked at tip. Incisor teeth small, 

 the innermost in the upper jaw shorter, rounder, and less pro- 

 minent than in Macropus^ the other two nearly equal in size, 

 with a distinct notch near the centre of the outer edge. The 

 fourth premolar in both jaws greatly elongated from back to 

 front, with a ledge on its inner side, and vertical grooves on 

 both sides. The two series of cheek-teeth nearly or quite 

 parallel. 



The Dorca Kangaroos, of which there are three species, are 

 confined to New Guinea, and form in some respects a connect- 

 ing-link between Macropus and the Tree-Kangaroos. With the 

 exception that they are not arboreal, little or nothing appears 

 to be known of the habits of these Kangaroos in a wild state.
