CANIS.

about 20 mm. in length. On the back of the neck the hairs are 30 mm. long, 
with their apical brown portions about 11 mm., and in places, from their being 
crowded together at the base of the neck when the head is slightly raised, a dark 
area is produced which is prolonged in a modified degree round the front of the chest 
as a marked collar. On the back, some of the hairs are 50 mm. long, 10 mm. 
of the tip being dark brown, succeeded by an almost white band 14 mm., followed by 
dark brown, which pales into light brown, and ultimately to whitish at the base of the 
hair. The juxtaposition of the white bands and the dark brown bands gives a 
brown and whitish mottled appearance to the fur, the general tint of which, however, 
is sandy yellowish w^hite, profusely and irregularly streaked with brownish. Imme¬ 
diately behind the shoulder there is a pale area in which only a few of the apices of 
the hairs are brownish, the rest of the hairs being yellowish white. The upper lip, the 
lower jaw, the cheeks, the throat (with the exception of the dark pectoral band), the 
chest, and under parts are yellowish white, but on the sides of the body there is no 
line of demarcation between the colours of the upper and under surfaces of the body. 
The limbs are yellowish sandy, but on the back of the thighs to the heels and around the 
genitalia there is a good deal of rusty red. On the fore limb a band of annulated hairs 
passes down from about the head of the humerus along the outside and then on to the 
front of the limb to the commencement of the metacarpus. As this band approaches 
the metacarpus some of the black tips to these hairs are but little more pronounced 
than in the rest of its course, so that no distinct dark spot is present, and in the female 
there is not the faintest trace of one. The hairs of the tail are yellowish white, but 
they terminate in such long blacki.'h-brown tips as to make the tail nearly wholly 
black, except on its sides for a short way from below the base. 
Male. Snout to vent 720 mm.; vent to tip of tail 285 ; height at shoulder 405. 
Female. Snout to vent 680 mm.; vent to tip of tail 240; height at shoulder 385 ; 
height of ears in front 64, behind 68. 
The female differs from the male in being much paler and more rufous, especially on 
the hinder quarters, but on the head, neck, and shoulders the two are exactly alike. 
The pectoral collar is a very pale sandy colour, and there is another similar band on 
the neck anterior to it. This second collar is prolonged downwards and backwards 
from the base of the ears. 
These much-faded specimens manifest a very faint indication along their sides of 
a darkening of the colour, which suggests that they may possibly correspond to 
C. lateralis. In the male, as also in the female, there is distinct indication of an 
oblique darkish band across the thighs. 
The measurements of the male skull are given in the following table (pp. 208-9). 
The skull of the Sennaar jackal, which has much the same form as the skull of the 
Tunisian jackal, but is of much smaller size, has not the longer and pointed muzzle of
