red, as on the rest of the body, are grey, owing to the hairs being white with black 
tips. The outside of the fore limb further down is not the pure white of the Eastern 
form, but is more or less tinged with pale yellowish brown, which is darkest on the 
dorsum of the foot, where this colour occurs in patches. 
In the Togoland specimen the top of the head is especially deep coloured, but not 
so much so as on the base of the tail; but the upper surface of the head is never so 
brilliant as in the Eastern form. 
In some young specimens from Western Africa the rufous of the outsides of the 
thighs and fore limbs is prolonged downwards in a narrow line to the upper sides of the 
feet, while in others this tint only occurs here and there on the parts of the limbs which 
are white in the Eastern form. In some of the young of the Western form the grey 
on the shoulder and the outside of the humerus is hardly present, its place being taken 
by rufous.

One of Kiippeirs specimens (I.E. 1.6) from Nubia has, as will be seen from the 
following description, all the characters of the type. 
This specimen is a pale sandy yellow, but slightly rufous down the middle of the 
back. The belly is nearly white, and also the inner and outer sides of the limbs, with 
the exception of the hands and feet. A few of the yellowish-white hairs on the 
shoulders are seen to have a trace of black tips, but do not appear to have had any other 
annuli. The upper surface of the head is rusty red, the whiskers are whiter than the 
rest of the body, and immediately above the external angle of the eye there is a 
blackish area, which is prolonged backwards as a fine dusky line over the occiput, and 
is continuous internally with the black and white eyebrows. The skin of the cheeks, 
along the upper lip, along the side of the nose, and over the inner angle of the eye 
is ochre-yellow ; a narrow area over the eye, the corners of the upper eyelids, and a 
triangular area below the eye and continuous with the dark area around the eye, of 
a similar colour. The nose has seemingly been dusky, but it is covered with yellowish- 
white hairs, which occur along the upper lip and on the chin. Upper half of the 
inside of the ears with a brush of long, whitish, erect hairs.

The pale colour of this specimen is probably largely, but not entirely, due to its 
having become bleached by long exposure to light for a period of over 70 years. 
Also in this Museum there is a seemingly adult female of a red monkey, said to
