The presence of canine teeth and horns had been stated by 
Professor Marsh as characteristic of a new order. Neither of 
these were regarded by Professor Cope as sufliciently important 
- for such an interpretation, since in Artiodactyles, and even in the 
-Ruminant division, we have every variety of condition in both 
these points; Moschide, Cephalophus and Hydropotes were horn- 
less, and some of these and some deer had canines. The wart 
hog has compound molars, no lower incisors and huge tusks. But 
the difference in this point from elephants he thought would dis- 
appear if, as was probable, the tusks of elephants should prove to 
be canines and not incisors. In these animals, as in Hobasileus, 
the tusk is enclosed between the maxillary and premaxillary, 
which is not the case with the outer incisors.
