50 MR. A. H. GARROD ON HALMATURUS LucTuosus. [Feb. 2, 
The following Table gives the most important measurements of 
the skin of the female Dorcopsis luctuosa, compared with specimens 
of the same sex of Dorcopsis muelleri aud Macropus brunit.

The general contour of the body is quite Macropine ; the breadth 
at the hips, however, is somewhat small. The hair is soft, short, 
and of a nearly uniform length all over the skin. 
The head is elongate and conical, the muffle naked, the eyes 
large and antilopine. The colour of the upper surface and sides of 
the head* and back is uniformly blackish with a silvery gloss, 
each hair being whitish at its base for two fifths of its length, black 
for the next two fifths, and white at the tip. On the ventral 
surface a broad longitudinal white band extends from the line 
joining the angles of the mouth, backwards along the neck and 
belly as far as the pouch, behind and from the sides of which it 
continues towards the tail of a true slate-colour as far as the cloacal 
orifice, between which spot and the base of the tail it is again white. 
This white band occupies the whole of the region between the 
angles of the jaw, and continues down the neck over the abdomen of 
a slightly greater width. It only encroaches on the sides of the 
body by sending an expansion into each axilla, which is visible 
laterally just behind the elbow. There is no lateral transverse 
white stripe across the front of the thigh, like that so strongly 
marked in M. brunit; and, unlike this last named species, the light 
grey, nearly white stripe above and parallel to the lip is very insigni- 
ficant, and does not extend backwards under the eye. 
The ear is rounded, black inside and out, with a slight white line 
formed by the similarly coloured roots of the there exposed hairs 
bounding the auditory meatus anteriorly. 
The non-exposed surfaces of both the arm proper and the thigh 
are of a pale grey. The other parts of both the fore and hind 
limbs are black. The nails of both the fore and hind limbs are 
short and Macropine. 
* The silvery white spot on the top of the head, mentioned in D’Albertis’ 
description, is not produced by the presence of white hair, but results from the 
fact that the spot where it is sometimes seen is the anterior junction of the 
forward-directed hair of the neck with the backward-directed hair of the frontal 
region. Its existence depends entirely on the way in which the hair is brushed ; 
and it is not visible except after the natural disposition has been disturbed.
