new Hedgehog from Southern Arabia. 43 
Bare area on the centre of the head well developed, beginning 
slightly anterior to the front border of the ears and prolonged 
backwards to the nape, tapered gradually from its base to its 
apex. The spines do not extend in advance of the anterior 
border of the ears. 
Head rather short and broad. lars very large and 
rounded, their height from lower border of external meatus 
to tip equalling in adults the length from the external meatus 
to the snout. 
In some individuals not quite adult the ears are somewhat 
shorter. Limbs strong and moderately long; fore feet broad, 
hind feet narrower, claws strong. ‘The palmar surface of the 
fore feet with a single broad pad, occasionally divided in two 
or nearly so, and when so divided the outer division is the 
larger. ‘Two much smaller, nearly equal-sized plantar pads 
on the hind feet placed side by side, and in some specimens 
more or less obliquely, with granular eminences between them 
and the digital pads. 
The spines in a broad area along the back have their tips 
nearly black, and in some individuals the tips of these spines 
are wholly black, whereas, in all, the spines on the sides have 
broad white tips; so that this hedgehog is distinguished by a 
broad black dorsal stripe with white sides. 
The whole of the face to beyond the eyes, the front of the 
forehead, and a stripe behind the angle of the mouth to below 
the ears, the chin, the back of the ears, a broad area of the 
internal borders, more especially the lower half of the inner 
border, black or blackish brown. Sides of the body below 
the spines, the limbs, tail, and around the genitalia likewise 
blackish brown. The throat, chest, and upper part of belly 
mixed white and brown in blotches. The insides of the ears, 
the sides of the neck below the ears, and the area between 
the ears and the eyes white. 
The above description is taken from an adult male in 
alcohol from the Hadramaut, collected by the Bent Expe- 
dition, which is taken as the type of the species, and from 
which the skull has not yet been extracted. 
In some individuals black prevails over all the parts, only 
a few greyish hairs being present on the forehead and front 
of the ears, below the ears and on the throat, but the white 
centre of the ears is present in all. In others, only the face, 
the fore limb from the elbow downwards, the hind limb, 
genitalia and the area around them, and the tail are black, 
the other parts being pure white, while in some brown hairs 
appear here and there on the white of the underparts.
