inclining to reddish, thickly interspersed vvitli long black hairs. 
Muzzle and face grey, whiskers dark brown or black. On the 
sides of the body the black hairs are less numerous and shorter, 
and the yellow colour lighter. On the lower surface the basal 
fur is grey, not so dark as on the back, and more broadly tipped 
with yellow, which however is very pale. Ears small, almost 
naked without, and sparingly clothed with short yellowish- 
brown hairs within ; laid forward, they fail to reach the eye by 
their own length. Limbs thickly clothed with greyish-brown 
hairs. Tail shorter than the head and body; the hairs are longer 
than two scales, but do not conceal them, they are not particularly 
stiff and are of black colour ; twelve scales to the centimetre.

Skull . — Stout, compared with 
Mus decumanus, deeper and con- 
siderably more arched, the nasal 
region shorter and thicker ; the 
nasals do not project beyond the 
line of the premaxillary, they 
are wide in front but taper back- 
wards, so that the posterior is 
only one-third the width of the 
anterior portion. The narrowed 
part is sunk below the level of Fig. 1. 
the premaxillaries which form a 
ridge on each side. The supraorbital ridge is very marked, and 
forms a distinct beading, but loses that character on the temporal 
region. The interparietal is short, but of average width, its front 
margin forming a nearly straight suture with the parietals. The 
anterior palatina foramina are narrow and extend backwards to 
the anterior margin of the first molars. The anterior zygoma root 
has the angle rounded, the front edge is vertical and slightly con- 
cave ; the foramen magnum is wider than deep. The mandible 
is very powerful, with strong muscle ridges; in front of the anterior 
molar it is nearly vertical, and the incisor capsule is large and 
deflected outwards.
