226 A NEW BORNEAN HERPESTES. 



In comparincr the skull of the Palembaug-specimen with 

 the other skulls* of brachyurus in our collection, I saw that 

 it agrees with them all, except with the skull of a speci- 

 men presented by Mr. Ch. Hose to our Museum. As the 

 differences between the skull of the latter specimen and 

 the other ones are so numerous and so very striking, and 

 as the skin belonging to that skull differs in many points 

 from the other skins, I think I am forced to regard upon 

 it as the type of another species. The material of the 

 true H. brachyurus at my disposal, all skins with skull, is :

c, e and ƒ have all traces of sutures 

 vanished by growing, I therefore call them adult, mean- 

 while the skulls of b and d show clearly all sutures not- 

 withstanding they are of the very size of the adult skulls; 

 I therefore call them fullgroion but not adult. The chief 

 difference between the adult and fullgrown ones further 

 is that in the latter the orbits form not yet a closed ring 

 and that they have the skull less broad than in the adult 

 ones; the lower jaws are all alike. I see no noticeable 

 differences in the skulls between males and females. And 

 now it is very interesting to observe, that Hose's specimen 

 the type of a new species, which I propose to baptize 



Herpestes Hosei, n. sp. 



shows besides a distinct coloration (see description of it 

 below) a quite differently looking skull ; the absence of 

 sutures, combined with complete orbits and used molars, 

 indicates that it belongs to an adult specimen; however 

 the skull is smaller than in brachyurus and the lower-jaw 

 presents a mach distinct aspect:
