canal is rather far back and close to the foramen ovale (not 

 the foramen lacerum medium, as erroneously stated by 

 Blanford, P. Z. S. 1885, p. 806). 



Teeth very large ; the /> 4 , m u and w? 3 broader than long, so 

 causing the peculiar shape of the palate, which somewhat 

 resembles that of Cynogale. In p 4 the anterior lobe of the 

 blade is as long as the posterior one (metacone), while in 

 Paradoxurus it is always shorter; the tooth is convex poste- 

 riorly, and has a strongly developed postero-internal ledge. 



Externally the new genus is characterized by the short 

 close fur, the annulated short tail, and the whorl in the neck, 

 the hairs of the neck and crown being directed forwards. 



In the skull as well as externally the differences which 

 separate this animal from Paradoxurus are very striking. 

 The new genus is a further one peculiar to Celebes. 



Paguma differs from Paradoxurus in having the palate 

 greatly produced behind, in the insignificant postorbital con- 

 striction, and the blunt postorbital processes. 



LXII. — Two new Mammals from the Malay Peninsula. 

 By Oldfield Thomas. 



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



Among the specimens which the British Museum owes to 

 Mr. H. C. Robinson's recent expedition to the northern part 

 of the Malay Peninsula is an enormous Arctonyx, very much 

 larger than any known member of the genus and obviously 

 needing description. 



It has, however, been known to Mr. Robinson for some 

 time under its native name " Sabima," and after much 

 enquiry he succeeded in obtaining the specimen now described. 



Arctonyx dictator, sp. n. 



Size decidedly larger than in other species. Fur long, 

 coarse, and harsh. General colour above dull buffy, overlaid 

 anteriorly by black, posteriorly by mixed black and greyish. 

 Hairs of the nape and anterior back buffy for their basal, 

 black for their terminal halves, of posterior back buffy for 

 their basal two-thirds, then black with a buffy tip. Scanty 

 hairs of under surface wholly black. Facial markings not
