figured ; therefore it is a great pity that the skull in our 

 collectiou (see plate 14) is that of a young or 

 half grown — the hind-most molar in both jaws are still 

 in their alveoles — individual, taken from a female — now 

 stuffed — collected by von Rosenberg on the Gorara- 

 island ; the posterior part of the skull is wanting and the 

 bony palate has been smashed. However, as something 

 always is better than nothing, I will describe this, although 

 incomplete, however unique skull. I compare it with the 

 skull of our Batian-papufinsis because both skulls are of 

 the same stage of development of the molars. Although 

 the general shape may be found to agree, the papuensis- 

 skuU is a good deal larger, the six — the hind-most is 

 not yet developed — upper molars taken together measure 

 83 mm. in the young papiiensis and 75 mm. in our niger; 

 five lower ones — the hind-most still absent — 75 mm, 

 in papuensis and 72 mm. in niger. The muzzle of niger is 

 not so elongated as that part in the young papuensis, 

 length of nasalia of niger 110 mm., of papuensis 128 mm., 

 the frontal bones in niger are shorter so that the skull 

 makes a more or less compact impression than in papuensis ; 

 intermaxillaria much less produced in niger; the orbits in 

 niger on the other hand are much more developed ; the 

 coronoid process in niger is less developed but much more 

 pointed than in papuensis; and so there are a lot of diffe- 

 rences sometimes insignificant in itself but all taken together 

 enough characteristic for specific distinction. In the left 

 ramus of the uuderjaw in my 7iiger-sku\\ there is no trace 

 of anterior premolar, although the named tooth is so well 

 represented in the right ramus — in papuensis the anterior 

 premolar is generally absent as I pointed out before. 



As to the black color of adult and very young speci- 

 mens I refer to wliat I broadly said in the Notes from 

 the Leyden Museum, 1891, pp. 102 and 103. A few words 

 concerning the ending of the tail. In our very young 

 specimen (from Ternate) of about 32 cm. from base of tail 

 to tip of snout, the hairs of the sides of the distant half
