rus with an 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 Schlegel says: „Onditgene- 

 ralement que les individus de ce singe apportes vivants en Europe 

 proviennent de Borneo. Nos voyageurs ne l'ayant observe, ni dans le 

 Sud, ni dans le Sud-Ouest de cette ile, il est permis de supposer qu'il 

 vient de la Cöte Nord Ouest , peut-etre par la voie de Labouan". 



The last author who has made original researches regarding our 

 monkeys , Andekson *) gives tbe 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. Tau short and stumpy. In 

 the young state the anirnal 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 stunipy". 



His afnrmation : „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 locality Borneo, than 

 „the sailor's wife" spoken of by Gray. A very doubtfull authority 

 indeed, doubted by Gray him'self. 



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.
