being entirely vanished by growing — with the exception 

 of the two hindmost molars on both sides, however totally 

 weared out, iu the lower jaw the two hindmost molars 

 are present ou both sides, further iu the right ramus the 

 anterior premolar and in the left ramus the anterior and 

 the fourth premolar, besides the anterior molar, weared 

 out however as in the upper jaw — and yet no crista is 

 formed by the parietals (distance 24 mm.) ! 



Professor Max Weber was kind enough to allow me to 

 describe this species and to study all the other Pig-skulls 

 brought together by him during his voyages in the East- 

 Indian-Archipelago; my sincere thanks to him! 



7. Siis timoriensis S. Muller. 



Although the adult form of this species is at present 

 unknown — the type-specimens too being semi-adult or 

 young ones — its specific value is beyond doubt. It may 

 be called a dwarf under its fellowpigs, for iu the type- 

 skull the distance between the parietalia behind (later crest) 

 is not more than 9 mm. and that notwithstanding solely 

 the hindmost molar iu both jaws is uot yet developed, 

 although clearly visible, so that we may safely conclude 

 that the skull has attained its full size ; the greatest length 

 of the skull is hardly 230 mm. (this skull has been figured 

 iu the » Verhandelingen", Tab. 31, figs. 2 and 3), mean- 

 while in a specimen of vittatus of about the same stage 

 of growth this measure is 328 mm. and the distance 

 between the parietalia 35 mm. I have here compared the 

 Timor-skull with a vittatiis because the original describers 

 have ventilated the supposition that the Timor-pig was in 

 all directions very closely allied to Sus vittatus — »in alle 

 opzichten zeer nauw verwant aan vittatus^' — and as I 

 venture to hold up another opinion. It is quite right that 

 the skull has the slender and elegant aspect of harhatus 

 and vittatus and that the bony palate is not far pushed 

 backward like in verrucosus^ however in vittatus like in
