the same colour above the eyes communicates a very peculiar and characteristic physi¬ 
ognomy to the patas, which led Buffon to describe it as the monkey a bandeau noir. 
One of the earliest accounts that we possess of the patas is given by an old 
French traveller, Brue, but it is not to be relied on in all particulars. A living 
example was first exhibited in the London Zoological Society’s menagerie about 
the year 1834, since which date it has been abundantly represented. This original

example, which was very young, was described as being lively and active, but 
somewhat irascible if disturbed or handled.

On the opposite side of Africa, in Nubia and Somaliland, the place of the 
patas is taken by a closely allied monkey, known as the nisnas. So similar, indeed, 
are these two monkeys that Dr. Gray considered them merely as varieties of the 
same species; and it is quite probable that if we knew all the monkeys from the 
intermediate districts of North Central Africa we should find that the one passed 
into the other. However, as they are considered by the learned secretary of the 
Zoological Society to be distinct, we must, at least for the present, allow them to 
stand apart. According to Dr. Gray, the nisnas is distinguished from the patas 
merely by the red colour of the body being continued on to the shoulders and the 
outer sides of the arms, instead of those parts assuming a blackish tinge. 
The nisnas is the species so frequently represented on the ancient Egyptian
