REMARKS It is of interest to note that when caught in the beam of the flash lamp this species sneaks or runs along the ground in the normal manner of other rats but when alarmed by a noise or gun-shot or it wants to get places in a hurry it hops like a kangaroo + can travel thus at a great speed, taking leaps of a foot with apparent ease! It carries its body in a more balled up or cuddled position + more up- right than as regards position of body over hind legs than a kangaroo. It does not appear to be as flat on its feet as a kangaroo but more on their toes.
