Swine is a name properly applicable to the domesticated pig, but also includes its wild relatives.
The Indian wild boar (Sus cristatus) is slightly taller than Sus scrota, standing some 30 to 40 in.
- Wild Boar and Young (Sus scrofa).
Some doubt exists whether the pygmy hog of the Nepal Terai, which is not much larger than a hare, is best regarded as a member of the typical genus, under the name of Sus salvanius or as representing a genus by itself, with the title Porcula salvania.
The milk-dentition, and even the early condition of the permanent dentition, is formed on the same general type as that of Sus, except that certain teeth are absent, the formula being 13 i cl, total 34; but as age advances all the teeth have a tendency to disappear, except the canines and the posterior molars, but these, which in some cases are the only teeth left in the jaws, attain an extraordinary development.
