able to describe the skeletons of adult female and male, 

 together with their skulls. Happily we have some measu- 

 rements of the typical male-skull, described by Mr. Miller; 

 the latter was kind enough to present me with some 

 photo's of the skull, meanwhile Mr. S. P. Langley of the 

 National Museum, Washington, had the extreme kindness 

 to allow me to publish these photo's if desired ; to both 

 gentlemen I express here my sincere thanks. Previously 

 I must confine myself to the following observations made 

 on the not-fullgrown skulls in our collection mentioned 

 above. As might be expected from such a remarkably 

 elongated head the skull indeed is proportionally narrower 

 and longer than in any other Pig-species, all the bones 

 are as it were stretched, the nasalia are much narrower 

 than in barbatus and more elongated, so that the skull 

 makes a still more elegant impression than in that species; 

 the premaxilla bones surpass the anterior border of the 

 upper incisor much more than in barbatus, in our skull 

 with six molars for about 9 mm., in the same skull the 

 beginning crista measures not more than 12 mm. and the 

 width between the zygomatic arches is only 118 mm. Like 

 Miller observed the skull so closely resembles that of Sus 

 longirostris (our barbatus) that it might readily be supposed 

 to belong to an individual of the same species. Although, 

 as we remarked above, there are several striking differences 

 between the two species, we may call Sus oi the represen- 

 tant in Sumatra of Sus barbatus. 



3. Sus verrucosus S. Muller. 



The type-specimen, an adult male, described and figured 

 in the » Verhandelingen", p. 175 and Tab. 28, has been 

 bestowed with the very appropriate title verrucosus after 

 its having the head adorned with a number of protuber- 

 ances or large warts ; there is a large protuberance above 

 each upper canine, another still larger one under each 

 eye, finally a very large one at a certain distance under
