 named. 



This pretty little opossum, the smallest marsupial of the 

 New World (with the exception of Peramys sorfx), may be 

 readily distinguished from its only near ally, Mirmosa pusill i, 

 Desm., with whicli M. agilis, Burm., would seem to be 

 identical, by its still smaller size, smaller secator, and much 

 longer tail. 



LTI. — Two new Macaques from W. Java. 

 By Oldfield Thomas and R. C. Wroughton. 



(Published by permission of tlie Trustees of the British Museum.) 



In a report recently presented by us to the Zoological Society 

 on the maonificent collection of mammals obtained in Western 

 Java by Mr. G. C. Shortridge, and presented to the British 

 Museum by Mr. W. E. Balston, the series of Macaque 

 Monkeys is referred to M. fascicuJaris, RafB. Now, how- 

 ever, in working out some mammals sent us by Mr. H. 0. 

 Robinson from the Malay Peninsula and Islands, we have 

 come to the conclusion that these Monkeys are not referable 

 to fasct'cularis, but belong to two species, neither of which 

 appears to have a Tiame. 



The first of these is a Javan representative of fasciculari^tj 

 while the second has quite a different skull, more like that of 

 the South-Indian M. sinica. 



Macaca mordax, sp. n. 



A large-sized macaque of the long-tailed type, rather larger 

 than M. fascicularis and with larger teeth than in that species. 



Fur coarse, 26-30 mm. long on lower back, 46-50 mm. on 

 shoulders. General colour a coarse mixture of brown and 

 I'uff. Arms and legs greyer, the grizzling less marked. 

 Cheeks and lower surface dirty white. Tail like back, 

 gradually shading, at half its length, into a grey-brown like 

 that of the arms and legs. A black line across the face above 

 the eyes. 



Skull about as in typical /asct'c./ /a ?vs, but somewhat larger 

 and with markedly larger teeth. The posterior nares com- 

 paratively large.
