THE ASHY-BLACK MACAQUE. 
Macacus ocreatus. 
Plate I. 
The group of Monkeys to which the name Macaque is applied contains some of the best known and 
commonest species usually met with in captivity, such as the Bonnet-Monkey, the Toque, and the Rhesus. 
They are found in a state of nature mostly in Southern Asia and its neighbouring islands. 
In the summer of 1858, the Zoological Society obtained a specimen of the rare Macaque here represented, 
out of a travelling menagerie. It was somewhat paralysed in its hind quarters when received, and did not 
promise to be very long lived. The species is certainly the same as that described by Mr. Ogilby in 1840,* from 
a specimen observed living in a menagerie at that time, and is probably identical with Macacus fwtco-aler of 
Schinz, in which case however Mr. Ogilby’s name has precedence. It belongs strictly to the division of 
Macaques in which the tail is very short, sometimes reduced almost to a tubercle, as in M. arctoides and 
M. mourns. There is no example of this species in the British or French national collections; but the I.eyden 
Museum contains two specimens, which I believe to belong to it. The example in the Frankfort collection is 
said to have been brought from Celebes, but I doubt whether that island is its real home.
