The short-eared Rock-Kangaroo is readily distinguished 
from the M. penicillatus and M. lateralis , by the absence of 
the black band on the sides of the body, the only remains of 
this dark line being confined to a patch immediately behind 
the base of the fore leg; its general colouring is paler, and the 
fur is much shorter. The tail is less bushy; its bulk is 
moreover inferior; and the proportionately small size of the 
ears is an important distinguishing character. In its smaller 
size, and in the reddish hue of the upper parts of the body, it 
approaches the M. coucinnm , but. besides other differences 
pointed out in the description, that animal does not possess 
any dark mark or spot on the sides of the body.
