rus with au extraordinary long muzzle , the other , a female was short 
muzzled with a black trunk and ashy limbs as a typical Macacus ocreatus. 
About the locality of Macacus maurus Sohlegel says: „ On dit géné- 
ralement que les individus de ce singe apportés vivants en Europe 
proviennent de Bornéo. Nos voyageurs ne l'ayant observé, ni dans le 
Sud , ni dans le Sud-Ouest de cette île , il est permis de supposer qu'il 
vient de la Côte Nord Ouest, peut-être par la voie de Labouan". 
The last author who has made original researches regarding our 
monkeys , Anderson gives the following definition of both. M. mau- 
rus: „Face and ears black. Buttocks surrounding ischia, flesh-colou- 
red or rosy. General colour of the animal sooty black, paler on the 
under surfaces and darker on the head. Tail short and stumpy. In 
the young state the animal less black than in the adult". 
M. ocreatus : „Face and ears nude and black. The trunk generally, above 
and below, brownish black, or tinged below with greyish. Arms and legs 
greyish externally on their radial and tibial portion. Tail short and stumpy". 
His affirmation: „inhabits Borneo" is based upon the following: 
„This monkey is not unfrequently brought to Calcutta from Singa- 
pore which port it reaches from Pontianak on the westcoast of Borneo". 
This proves nothing at all. 
1. In such a centre as Singapore are brought together very different 
animals from various countries as is very well known. 
2. From my own experience I may say that there are more ves- 
sels reaching Singapore from Makassar (the habitat of Macacus ocrea- 
tus) than from Pontianak. 
3. Pontianak was visited very often by Dutch and other travellers 
but none of them ever brought from there any Macacus maurus. I 
therefore know, of no other authority for the locahty Borneo, than 
„the sailor's wife" spoken of by G-ray. A very doubtful! authority 
indeed, doubted by Gray himself. 
In the second place I believe that there is no real Macacus maurus. 
Different authors, quoted above, have already stated, that it is im- 
possible to distinguish, when young, Macacus maurus and ocreatus. 
When older some of them become black with greyish limbs, these 
are called Macacus ocreatus, those remaining brownish black are cal- 
led Macacus maurus.
