MACKOrODlP.*:. 
I have seen but one specimen of this species of Rock- 
Kangaroo, which is so remarkable for its brilliant colouring 
and small size, being scarcely equal in bulk to most of the 
Kangaroo-rats: this specimen was brought to England by 
Lieut. Emery, of H. M. S. Beagle, and is now in the British 
Museum : no peculiarities in its habits are mentioned in the 
only published account which 1ms as yet appeared. 
The Macropus concinnus may be readily distinguished 
from its congeners, not only by its small size and bright 
colouring, but by the absence of any black spot behind the 
base of the fore leg, The head is of a palish ash colour 
above, slightly suffused with rust colour, this latter tint 
being most conspicuous above the eyes ; the checks are rusty 
white, and have an indistinct greyish brown mark extending 
forwards from the front of the eye; the ears are of moderate 
length, narrow and somewhat pointed, brownish (but very 
pale) externally, and with a few white hairs internally. The 
fur on the back is grey next the skin, and this tint, at tlie root 
of each hair, is followed by brilliant rusty red, then a broad 
space which is white, and the tip is deep rusty brown; on the 
under parts of the body the fur is grey next the skin, and 
has the visible portion yellowish white* The fore legs are 
rusty white, and the hands a brown-white; the hind legs are 
of a pale rust colour externally ; the tarsi are brownish white, 
but slightly pencilled with brown : on the back of the neck is 
an indistinct trace of a mesial darker mark. The tail is 
clothed at the base with fur like that of the body ; beyond this 
the hairs are of a harsher nature, at. first about half an inch 
in length, and on the apical third they are about an inch and 
a half in length, of a brownish white colour, hut tipped with 
black.
