SUS-STUDIES. 175 



a mere matter of convention; so Mr. Miller and I decided 

 to call the Sumatra-species by the old name given by 

 Muller and Schlegel, Siis vittaius; and I propose to give 

 to the Java-species the name of my ingenious friend who 

 first drew our attention to the specific distinctness of the 

 two species, and therefore to baptize it Sus Milleri. 



4. Sus vittatus S. Muller. 



In a young state the animal is adorned with alternately 

 black and reddish brown bands along the sides of the 

 body; by advancing age these bands vanish so that in 

 fuUgrown individuals the body is of an uniform dark varied 

 with reddish brown ; the line along the spine however is 

 black, with longer bristles towards the nape of the neck 

 where they form a crest; these black bristles are broadly 

 reddish tipped. 



In fullgrown specimens there is a broad brownish red 

 band over the middle of the snout, broadening over the 

 sides of upper lip and corner of mouth, running over the 

 lowerlip straight backwards ending in a point or rather 

 vanishing on the lower parts of the neck. In very old 

 individuals the described band is often very inconspicuous. 

 All the other bristles on the head and those on the body 

 are black with a subapical reddish brown ring, giving 

 the animal a much more reddish tinge than the individuals 

 of Milleri, the Java-species ; the bristles on the middle of 

 the back have reddish brown tips, without doubt because 

 the black tips have been scoured off against the low shrubs 

 they meet in their footh-ways. No warts, protuberances 

 or tufts of bristles like ou the head of harbatus and ver- 

 rucosus. Ears in size between these species, ending in a 

 well developed somewhat outwards turned tip. The head 

 is shorter than in the named species and the profile-line 

 is slightly curved, in fullgrown specimens straight, in very 

 adult ones feebly curved. Tail ends in some elongated 

 bristles forming a flat small tuft. Muller described nose
