MALAYAN PIGS. 69 



are found respectively Sus niadensis, Sus babi and Sus mimics 

 all described for the first time. The animal that occurs in the 

 islands of the Natunas between the Peninsula and Borneo is 

 Sus natunensis. Miller, while Sus nicoboricus, Miller, is known 

 as yet by specimens from Great Nicobar Island only. The 

 smallest member of the group — smaller even than nicobaricus or 

 mimus, is Sus andamanensis, Blyth. from the Andaman Islands. 

 The paper contains full descriptions, keys and measure- 

 ments, and is illustrated by many plates (amongst which are 

 reproductions of a mounted Sus barbatus), of mandibular teeth 

 and skulls in various aspects, all of which greatly facilitate 

 the identification of the different species.
