woodward i, and the more accurate knowledge of M. tsabellittus , are all 
due to Mr. Woodward. 
Still further north-eastwards from the range of the present animal, 
in the Northern Territory of South Austrrlia, occurs M. antilopinus 
(Gould), which is of a somewhat similar color and general appearance, 
but differs markedly by the pecular inflation of the sides of the muzzle. 
1 he hair of its nape slopes uniformly backwards. 
MACROPUS ROBUSTUS ALLIGATOR IS, sub-sp., nov- 
Type. — No. 1445. July 2nd, T903. South Alligator River. 
“ Chackaru ” of Natives. Iris-brown. J. T. Tunney. 
Fur nearly as short and close as in M. r. woodwardi , much 
shorter than in the other sub-species. 
N.B. — This species does not occur in W.A., but is included in 
this list as it is so near a neighbour and belongs to the group described 
above.

DENDRODORCOPSIS, sp. nov.- 
This genus is closely allied to both Dorcopsis and Dendrolagus, 
and in many respects stands intermediate. It differs from both in its 
much more hairy rhinarium and very short claw to middle toe of 
hind foot, which is concealed by the hair of the foot above, and only 
exceeds the pad of the toe in length by 6 millimeters. The naked 
pad ot hind foot large, strongly rugose and extending up the back of 
hind legs as in Dendrolagus. Hind leg much longer than fore leg, as 
in Dorcopsis. Tail considerably shorter than body, covered with 
short, flat, and straight hair as in Macropus. Mr. Oldfield Thomas 
has examined the skull of this curious new kangaroo, and finds that 
its essential generic characters (especially the absence of the canine 
teeth) do not differ from those of true Macropus. This makes the 
genus much more interesting, as the external generic characters show 
almost conclusively that it is aboreai as well as rock-hunting in its 
habits, which fact would account for its modified outward resemblance 
to the l Inlanders and T. ree- Kangaroos, while it nevertheless retains 
the essential macropine cranial characters.
