26 DR. J. E. GRAY ON THE SUID^. [Jan. 9, 



from Mr. Wallace's collection. Length 12, height 8^ inches. The 

 concavity in the front of the orbit is dee^ier, and the ridge separating 

 it from the cavity of the orbit more marked. The process of the 

 sheath of the uj)per canine is similar, but rather larger, the upper 

 edge is sharp-edged at the end, longer, more ovate, convex, and 

 rugose. 



No. 1362 A. Skull of au old male from Batchian, from Mr. Wal- 

 lace's collection. Length 13, height at occiput 8{- inches. Very 

 like 1 362 d from Amboyna ; but the forehead is nari'ower and flatter, 

 and the nose broader, being rather wider in front over the canines 

 than in front of orbits ; the concavity in front of the orbit similar 

 and deep, and with well-marked outer orbital ridges. The process 

 of the sheath of the upper canine is shorter, thicker, blunter, with 

 a rounded end, and without any distinctly sharp crested front edge. 



No. 1362 b. Skull of an adult, with well-worn grinders, a " Wild 

 Boar from Java," from Mr. AVallace's collection. Length 13|^, 

 height 8|- inches. Very similar to S. vittatus from Amboyna 

 (1362 c and 1362 rf); but the nose of the skull is rather broader, 

 especially in front, and the sheath of the upper canine is only fur- 

 nished with a well-marked ridge behind. The concavity on the 

 cheeks is very deep and wide in front, but not so well marked and 

 deep on the hinder edge, where it is separated from the orbit by a 

 wide flattish space. 



No. 1362/. Skull of an animal developing the hinder molar; the 

 concavity in front of the orbit not so deep and well marked, as usual 

 behind ; z3'gomatic arch and lower jaw swollen on the sides ; the 

 ridge of the sheath of the canine slight and sharp-edged. From 

 the Utrecht Museum ; probably from Java or some of the Dutch 

 colonies. Length 13, height 7 inches. 



No. 1362^. A skull of an adult, received from the Utrecht Mu- 

 seum without any habitat, but most probably from Java, is very like 

 the preceding; it is 12^^ inches long and 7^ inches high at the oc- 

 ciput.

Mr. Swinhoe gave an account of the habits of the Pig in Formosa 

 (P. Z. S. 1862, p. 361). It is a Sus, and not a Porcula. 



Mr. Swinhoe (P. Z. S. 1862, p. 36) thinks this is a Wild Pig, the 

 original stock of the Chinese Domestic Pig. 



Mr. Blyth says this is the animal from which the Chinese Do- 

 mestic Pig is supposed to be derived. There are three animals in
