and three on the right side, and three embryos are attached on each side, the 
remaining mainma3 being small and evidently not recently used. In four 
smaller one six mammte are present, three on each side, and two embryos have 
been attached on each side. It is the anterior inammie which have disappeared.

(Plate II., Figs. 1, \a, \b, Ic. Plate IV., Figs. 9, 10, 11, 12). 
Size medium, the fur moderately coarse. The general colour of the back is 
dull greyish-brown, with a well-marked chestnut patch behind each ear. The 
ventral surface is grey. There is a light line above and below the eye. A light 
line runs along the upper jaw, and is continuous at the angle of the jaw with the 
white ventral surface of the head and lower jaw. 
Ears rounded; clothed inside and out with short, light-coloured hairs; 
reaching, when laid forward, to the middle or close to the anterior end of the eye. 
Hands and feet grey above. 
Palms with six striated pads ; the proximal half of the pollical pad curved, 
with the concavity facing inwards; the proximal outer pad V-shaped, with the 
apex pointing towards the fingers, the inner leg of the V being very slightly longer 
than the outer. 
There is a small tuft of white, whisker-like hairs placed on the posterior side 
of the fore-arm, just above the wrist. 
Soles naked except under the heel, where they are hairy; granulated; the 
hallucal pad divided into two; hallux reaching slightly further forward than the 
proximal end of the anterior pad of its side. Pads six in all and distinctly 
striated. 
Tail shorter than head and body; notably stout for its proximal half; 
tapering rapidly at about the middle of its length, and from this gradually to the 
tip; markedly incrassate ] covered with fairly-long stift’ hairs, but with no crest. 
In colour somewhat lighter than the body, the ventral being somewhat lighter 
than the dorsal surface. 
Pouch only slightly developed, opening vertically downwards. Two lateral 
folds of skin ; within the pouch area the hairs are comparatively scanty and light- 
coloured throughout; external to the pouch area the hairs are dark-coloured for 
their basal two-thirds, the pouch area being thus cleaidy marked out, and the folds 
being doubtless more developed when young are present.
