HEUDE'S CHINESE MAMMALS.

wrongly labelled *S y . nipponicns, from Central Japan. The skulls 

 of the Yang-tze pigs are not only considerably larger than this 

 specimen from Japan, but are proportionately much longer. It 

 is interesting to note, hpwever, that the Yang-tze pigs, in common 

 with most of the pigs in China, have the peculiar whisker-like 

 white patch on the cheek, which gives its name to the Japanese 

 pig *S V . leucomystax.

In comparing the three adult male skulls from Shensi, labelled 

 S. oxyodontus, S. laiiceps, and S. curtidens respectively, with each 

 other I can find little grounds for separating them. All three 

 were collected in 1883 by the same collector, M. Yidi, and, as 

 there are no data to the contrary, one must presume from the 

 same locality in the region of the Upper Han River, S. Shensi. 



Compared with the type of S. paludosus the Shensi skulls are 

 all smaller and proportionately shorter and broader — in fact, the 

 broadest of the three (S. laticeps) is actually a few millimetres 

 wider than the Yang-tze skull, though it is fully 4 - 5 centimetres 

 shorter. As, however, no description accompanies any of the 

 three names oxyodontus, laiiceps, and curtidens, while the speci- 

 mens appear to agree with Milne-Edwards' Sus moupinensis from 

 further west, I should suggest considering the Shensi pigs as 

 belonging to that species, till further and more reliable data as 

 to their representing a distinct form are forthcoming. Indeed, 

 Heude himself applied this name to a skull of a sow from 

 the same district from which the other Shensi skulls came. 

 Mr. Gerrit S. Miller has referred a specimen of a wild boar shot by 

 me near Yen-an-fu in North-Central Shensi to Milne Edwards's 

 species. 



It is interesting to note that the wild pigs from Slmnsi also 

 have wide skulls, and specimens sent by me from the Ning-wu 

 district in the west of that Province to the Smithsonian Insti- 

 tution have been determined by Mr. Miller as S. moupinensis. 

 An old boar examined by me in 1910 gave the following skull- 



measurements :— 



Condylo-basal length 395 mm. 



Zygomatic width 175 mm. 



Width across postorbita.l processes of 



frontal s 127 mm. 



These measurements show a. greater proportional width than 

 an even larger skull from Chinkiang secured December 1915 

 by Mr. A. H. Rasmussen, whose property it remains, which 

 measured : — ■ 



Condylo-basal length 400 mm. 



Zygomatic w T idth 166 mm. 



Width across postorbital processes 



of frontals 110 mm.
