that tint below the exposed ends ; under parts pale grey, 
slightly suffused with yellowish; upper surface of head and 
muzzle sooty brown, nearly black on occiput and back of ears, 
which have, however, yellowish hairs at the base; internally 
they are yellow, but margined with black at the apex ; cheek- 
mark yellow-white; chin with a black spot; legs and feet 
yellow, excepting the fore half of the latter, which is black; 
tail long, grey, with the tip black, and having long black 
hairs (forming a kind of crest), both on the upper and under

I feel no doubt that the Macropus Irma and the M. 
manic at us are varieties of the same species; since, however, 
they differ in some respects, it is necessary to state that the 
above diagnosis is drawn up from Mr. Gould’s original speci¬ 
men of the M. manicatus , a very elegant and beautiful 
Kangaroo. Its fur is moderately long and moderately soft;

body; indeed, the lower part of the abdomen is almost entirely

brown, and a faint rufous hue is just traceable on the crown
