harhatus the premaxilla surpasses the anterior border of 

 the upper incisors, but not in timoriensis, and in the upper 

 jaw of timoriensis the distance between the anterior pre- 

 molar and the canine is greater than in vittatus. Now 

 every one is free to make speculations over the unknown 

 origion of the Tiraor-pig, it is a fact that there at present 

 is living a dwarf-pig in wild condition, distinct from the 

 other Malayan pigs. We have in the collection 6 skulls 

 procured and presented to our Museum by Dr. H. ten 

 Kate from the Timor-island and labeled by him »tame 

 pigs", besides two skulls more collected by him at Landoe, 

 Roti, labeled »wild pigs"; none of these skulls is fullgrown; 

 practically I cannot detect any difference between Dr. ten 

 Kate's »tame" and y-wild" pig-skulls mutually, and on 

 the other hand the typical Timor-skulls present no diffe- 

 rence with ten Kate's specimens; that is to say the skulls 

 labeled as from »tame" pigs make the impression as if 

 they belonged once to specimens of a somewhat larger 

 size, as in skulls of the same age and size the distance 

 between the parietalia behind (later crest) is a good deal 

 greater than in our typical »wild" specimens. If I may 

 be allowed to make a suggestion then here is a great 

 motive to suppose that the »tame" specimens living in 

 Timor in confinement are of springs of tamed individuals 

 of the wild pigs living in Timor; the reverse is not very 

 likely as we hardly can suppose that the indigenous should 

 have brought over from abroad » small" pigs to keep in 

 confinement, and even not that true tamed large-pigs in- 

 troduced from abroad should have given rise to a »tame" 

 dwarf-pig- race, that escaped and grew wild ! Without 

 making all sorts of conjectures relating the origin of Sus 

 timoriensis, as a matter of fact it has certainly nothing in 

 common with Sus floresianus or another known small Pig- 

 species. 



Dr. S. Muller, who with Dr. Macklot collected our speci- 

 mens in Timor stated: »that very young specimens are 

 "striped or banded like in the young vittatus, that however
