THE MAMMALS OE EGYPT. 
oue, but the tints of the upper surface are less vivid, the white supraorbital band less 
distinct, and the upper surface of the hands and feet darker. 
The third specimen (9095), from the Blue Nile, differs much from the foregoing in 
having the upper surface of its head rich golden yellow, the hairs being broadly banded 
with yellow subapically, with a well-detined black tip. This colour to a somewhat 
less degree occurs on the back and sides, but less so on the rump and still less on the 
outside of the humerus. The outsides of the thighs and of the fore limbs are pale 
slaty greyish brown, but with little speckling. The hands and feet are of the same 
colour, but slightly darker. The white orbital band is well defined, and the whiskers 
are long and white. The tail above is greyish brown, finely speckled, but greyish 
white towards its tip. 
Besides the foregoing specimens, there are four skins in the Berlin Museum from 
Abyssinia. 
1. ^. 9100. Tigre, Schimper. 
This specimen has the general characters of the AVhite Nile male, but the tip of the 
head is distinctly yellowish, and the whole of the upper surface has likewise a yellow 
tinge, but paler than the head. The forehead is blackish, only a few of the hairs 
with narrow subapical pale yellowish bands, each hair terminating in a black tip. The 
pale frontal band is much the same as in the White Nile male, and not so white as in 
the female from the Blue Nile, no. 9095. The hairs at the extremity of the tail, for 
60 to 70 mm. of its length, are yellowish white. 
2. ? . 9099. Tigre, Schimper. 
This specimen has the general colour much as in the last mentioned, but the forehead 
is not so blackish grey, and the yellowish tinge on the head and back is pale. The 
tip of the tail is greyish white with a yellowish tinge. 
3. ^ juv. 9096. Tigre, Schimper. 
This specimen is slightly more yellowish than the previous one. Its frontal band is 
better defined, and the last portion of its tail (70-80 mm.) is pure yellowish white. 
4. $ adult. Salomona, Abyssinia, near the coast. 
The general colour of the upper surface of this animal is more decidedly yellowish 
above than in the last three monkeys, and in this respect it is more like the specimen 
from the Blue Nile. The sides of the neck, the thrcjat, and part of the chest have a 
decided yellowish tinge, and the hairs internal to the ischial callosities are brilliant 
rusty red, not due to any adventitious substance. The tip of the tail has been almost 
denuded of hair. 
In specimens referable to the West-African form with yellow whiskers, the rufous 
area internal to the ischial callosities is sometimes present.
