TAGASSU. 61 
The members of the first Family of the Ungulates to be con- 
sidered, the Peccaries, differ from those of the family Suide in 
various respects. They lack one pair of upper incisors, and the 
anterior premolar in each jaw. The canines, large and formidable, 
are directed downward, not upward, and the last premolar is 
complex. The stomach has three compartments, and is more com- 
plicated than that of the true pigs. These animals are fearless and 
pugnacious, associate in droves, sometimes of considerable numbers, 
and when attacked, all assume the offensive, and are capable of 
doing much damage with their sharp tushes, and a man in the midst 
of a number of enraged Peccaries is fortunate if he is able to find a 
tree to climb, that being about the only method of saving his life. 
Two species have been long known, but lately a number of others 
have been described, some of which may prove to possess distinctive 
values.

* Messrs. Gill, Allen, and Thomas (l.c.) have given their views regarding the 
proper generic names for the Peccaries, each arriving at a different conclusion, 
no two of them agreeing, and thus exhibiting, in a certain degree, the very 
unstable foundation on which nomenclature rests. Not wishing to add to the 
confusion by giving another opinion, even if it were necessary, 1 have fol- 
lowed Dr. Allen, whose argument is apparently the strongest of the three. 
Mr. Thomas in a later publication abandons his position and accepts Dr. Allen’s 
view (l. c.).
