713 s. The skull of a very young Domestic Pig. This skuU has 

 an abnormahty in the cutting- teeth. There are six in the upper 

 jaw ; the first two are in their natural position, and in their proper 

 place ; the two hinder ones on each side are close together, just in 

 front of the suture of the intermaxillary bone, the front one being 

 elongated, slender, conical, and bent outwards, and the hinder one 

 short, broad, conical, and compressed. The canine on the right 

 side is double ; that is to say, the new one has appeared before the 

 old one has been shed. 



713 w. Skull developing its last grinder, from the Museum of Dr. 

 de Jeude. ■ 



713 1. Skull of an adult, with the nose of the skull more elon- 

 gated; from the Utrecht Collection. Probably half-bred between

 the Domestic Pig, and the length of the face like the wild breeds.

This genus is most allied to Potamoehosrus in the form of the 

 skidl, and to Sus in its external appearance. It is not likely to be 

 a cross breed between the two genera.

 tered- black bristles. Skin blackish grey. Limbs and beneath
