Hind limbs proportionately less elongated than in AZacropus ; 
naked portion of nose large, broad, and wholly devgid 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-

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

parallel.

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