SECOND YARKAND MISSION. 



passages is not completely divided. The palatine bones terminate near their suture in small 

 points projecting backwards. The anterior palatine foramina are shorter, broader, and very 

 differently shaped, being much more oval and not acuminate behind. The zygomatic arch 

 is deeper, and the ante-orbital foramen is less open and has a thread-like horizontal process 

 stretched partly or completely across its orifice. 



How far these differences entitle the Thian-Shan pig to specific distinction I cannot 

 say without much better means of comparison than I possess at present. If the cranial 

 differences pointed out are never found in European pigs, and if the black legs are equally 

 unknown in typical Sits scrofa, the animal of Turkestan may have fair claims to be separated. 



The following are comparative measurements of the two skulls from the Thian-Shan 

 mountains, and of the Hungarian skull already referred to —

Whether this form is the common pig of Turkestan or not I have no means of ascer- 

 taining ; neither Severtzoff nor Prejevalski mention any peculiarities in the colour or 

 structure of the wild swine noticed by them. The only Central Asiatic hog hitherto distin- 

 guished from S. scrofa is the S. moupinensis of A. Milne Edwards 1 from Eastern Tibet, and 

 it is uncertain whether this is not Himalayan (i. e., oriental) and not Tibetan.
