reproduction, however the artist made a cardinal mistake ! 

 He namely replaced the — as I said above — worn-out 

 or absent molars by other ones, in order perhaps to furnish 

 a more complete and nicer looking drawing; that the artist 

 drew non-existing molars may be demonstrated by the 

 fact that he figured eight lower molars instead of seven — 

 and we never possessed a skull with eight molars ! Professor 

 Rolleston ^) and Nehring ^) have fixed the attention upon 

 this curious phenomenon — although they could by no 

 means suggest that it really was a mistake by the artist 

 and not an abnormity. 



Figure 2 on plate 10 will give a fair impression of the 

 underside of this old male-skull. 



As I remarked Forsten's specimens were procured from 

 North-Celebes (Menado) ; other individuals from North- 

 Celebes are in our Museum, they have been collected by 

 von Rosenberg in 1864 at ToelaboUo, Gorontala. 



There is however in our collection a skull of a full- 

 grown specimen, collected by Bernstein in South-Celebes; 

 this skull does not agree with the above described true 

 celebensis-skvWs, ; other skulls, adults and young ones, col- 

 lected by Prof. M. Weber in South-Celebes, Bira, Kadjang, 

 Loka and Pare- Pare, differ as much from the true celebensis 

 from North-Celebes ; it is a pity that all these South- 

 Celebian skulls are without skins! — Is perhaps this animal 

 an other species? Now it is highly interesting to remember 

 that Prof. Nehring (ueber Sus celebensis und Verwandte, 

 p. 27) wrote: » wichtig ware es, wenn zukünftige Forscher 

 "und Forschungsreisende ihr Augenmerk auf folgende Punkte 

 "richten wollten : . . . 4. Lassen sich constante Unter- 

 "scheide zwischen den aus der Minahassa und aus den aus 

 "Süd-Celebes stammenden Exemplaren des Sus celebensis 

 "beobachten ?" That sharp-sighted investigator had as it
