52 Miller. — A New Pig from Sumatra. 



skin. On sides and belly they are very stiff, closely appressed and di- 

 rected backward, about 20 mm. in length and nearly .5 mm. in diameter. 

 On legs they are less coarse in texture and sufficiently numerous to pro- 

 duce a distinct dark shade. Along middle of neck and back they in- 

 crease in length to about 50 mm., the diameter at the same time de- 

 creasing to .3 mm. The hairs form no mane, but throughout the re- 

 gion where it occurs in other hogs the hairs are less scattered and 

 appressed than elsewhere. They are black, tipped with yellowish 

 brown. Head as in Bus barbatus*, except that about midway between 

 eye and muzzle there are two well-developed protuberances 30 mm. in 

 length and 20 mm. in breadth densely covered with stiff antrorse bris- 

 tles. These bristles as well as those of the upper part of the face are 

 uniformly yellowish brown. On cheeks they are strong!}' intermixed 

 with black. Tail scantily covered with stiff black hairs about 25 mm. 

 in length. They nowhere conceal the skin, but on terminal third are 

 sufficiently close-set along sides to form a distinct flattened brvish. 



Skull. — The skull so closely resembles that of an adult male Sus hn- 

 girostris from Borneo that it might readily be supposed to belong to an 

 individual of the same species. 



Teeth. — The teeth, with the exception of the canines, are uniformly 

 smaller and narrower than those of Sus lojigirostris. Upper incisors 

 wide apart, the second separated from both first and third by a space of 

 15 mm. (in S. longirostris the distance between second and first is 5 mm., 

 that between second and third only 2 mm.). Posterior upper molar 

 with last tubercle less than half as large as in the corresponding tooth 

 of *S'. longirostris. Third lower molar consisting of only two cross ridges 

 and a terminal heel, the entire length of the tooth much less than that 

 of the two preceding teeth combined. In form it closely resembles Neh- 

 ring's figure of the same tooth in Sus celebensis\ and is very different 

 from that of Sus longirostris and Sus cristatus.X

 form, that is with three cross ridges and a terminal heel.
