4. Skull of an adult male, from South-Celebes, Pare-Pare, 

 collected by Weber, 1888. Without lower jaw. 



5, 6. Skulls of a fullgrown male and ditto female, South- 



Celebes, Doodengrot (death's grot) near Bira, collected 

 by Weber, 1888. The male-skull without lower jaw. 

 7. Skull of an adult male, Saleyer-island, from Weber's 

 collections, 1889. 

 The skull of the Saleyer-iland agrees in shape, size and 

 measurements very exactly with the skull figured and 

 measured by Dr. A. Nehring in his paper »ueber Sus 

 celehensis und Verwandte" ; I mean with skull 1538, Dresden 

 Museum, too from Saleyer, figured Abhand. Museum, Dresden, 

 1888/80, Taf. I, fig. 1 and Taf. 11, figs. 2 and 8; they 

 both are adult male-skulls. In comparing this Saleyer- 

 skull with the two adult male-skulls from Pare-Pare and 

 Bira and also with Bernstein's South-Celebian female-skull 

 we state the very interesting fact, that although the named 

 skulls do not perceptibly differ in size, the upper molar- 

 series taken as a whole is much larger in the South-Celebian 

 skulls, especially the three hind-most molars are much smaller 

 in the Saleyer-skull : in mm.

upper molar series 93 96 95 103.5 



the three upper true molars 54 57.5 58 62 



In the Saleyer-specimen from the Dresden Museum these 

 measurements are 89 and 52, therefore still smaller than 

 in our specimen. Is perhaps the Saleyer-island animal a 

 smaller form of the South-Celebian species? The material 

 is too incomplete to discuss this interesting point! We 

 have now to describe this skull of the Saleyer, an old 

 male-skull with its lower jaw. For the present I think it 

 wise to give only previously another specific title to the 

 Saleyer-Pig; if it laterou appears that there exists truly 

 a specific difference between the Pigs of South-Celebes and 

 those of the Saleyer then the Saleyer-species once for all 

 may be Sus Weberi.
