546 ON THE DOMESTIC PIG OF 



II. Sus scrofa, YaY.fertis^ and its allies. 



' Sus Uhycua.' British Museum, 713 a. ' JTah. Asia Minor, Xanthus (Sir Charles 

 Fellowes). The skull is very distinct from all the skulls of the wild boars from Ger- 

 many in the British Museum.' The animal was just about eighteen months old : its 

 interectorbital region is still convex ; but it has no very marked lacrymo-frontal ridge ; 

 its naso-frontal suture is convex backwards, as in Sus scrofa, var. ferus ; its nasals are 

 8 in. long, as against 14I of total skull length ; and the height of the lacrymal is less 

 than its inferior length. Here it resembles Siis scrofa rather than Sus cristatus. 



Height of lacrymal i in. ; malar border 0.15 in. 



Wild boar from Germany, Sus scrofa, var. ferus, 3253 a, E. C. S. England. Adult. 

 Height of lacrymal 0-9 in. ; malar border 1-5 in. 



Wild boar from Germany, Sus scrofa, var. ferus. 0. U. Museum, 15 13 a. All

Height of lacrymal i in. ; malar border 1-5 in. 



Wild boar from Germany, Sus scrofa, var. ferus. 0. U. Museum, 151 3. Presented 

 by Professor Max Miiller. With all the teeth, except third molar, in use ; sixteen

Young wild boar, Sus scrofa, var. ferus. R. C. S. England. With first molar only 

 through, therefore between five and six months old, with frontals still very convex in 

 vertical aspect, but with flat lacrymo-frontal ridge. 



Height of lacrymal 0.7 in. ; malar border 0.7 in. ; frontal border 1-5 in. 



Skull of old wild sow, Sus scrofa, var. ferus, from alluvium near Oxford. Figured 

 plate xli. fig. 2, from the Geological Collection, O. U. Museum. 

 Height of lacrymal 17 millims. ; malar border 18 millims. 



Skull, from peat, of wild sow, Sus scrofa, var. ferus. British Museum. With third 

 molar through. 



Height of lacrymal cS in.; malar border 1-05 in. 



Skull from silt of old bed of Lea river, shown to me in British Museum Geological 

 Collection by Mr. Davis. Under eighteen months. 

 Height of lacrymal 0.6 in. ; malar border 0-5 in. 



Second skull from same locality, and in British Museum, with all the teeth in place, 

 and the third molar with considerable complexity in its posterior lobe. 

 Height of lacrymal 0'6 in. ; malar border 0'8 in. 



Skull of Su^ scrofa, v&t. ferus % British Museum, 713 *'. The animal was about 

 sixteen months old, all the teeth being in place except the third molars above and 

 below. There is stiU some convexity across the frontals, though flattening is begin- 

 ning on either side towards the ectorbital processes. The lacrymo-frontal ridge is not 

 markedly convex ; the nasals are convex backwards in the middle line. 



Height of lacrymal 0-9 in. ; malar border 0-75 in. 



Skull oi Sus scrofa, var./erws? British Museum, 713/1;. The frontals are convex 

 from the level of the supraorbital foramina backwards ; the fronto-nasal suture is 

 straight, nearly as it is represented in the young German wild boar (Nathusius, i. c. 

 Taf. iii. 12). Lacrymo-frontal ridge is slightly convex. 



Height of lacrymal 0-75 in. ; malar border 0-5 in.
