cisors ; and, second, the slight development of the flange of the 
lower jaw. e angulation of the anterior part of the lower 
jaw is very well defined, but does not descend as a flange below 
the level of the inferior border. The anterior face is well dis- 
large size of the canine and small size of the incisors. The 
latter are three in number, and the roots are much compressed, 
and so crowded as to alternate with each other. The crowns are 
lost. The canine is considerably compressed, and has a sharp 
serrulate posterior cutting edge, which descends to the base of 
the crown behind. There is no anterior cutting edge. The 
shape of a section of the tooth is lenticular, the anterior angle 
rounded off; the long axis extends a little oblique to the median 
line. The apex is lost. There are three foramina on one side, 
and two on the other of the median symphysis; and there arè 
three mental foramina on the best preserved ramus.

The large size of the inferior canine might lead to the ioke 
_ ence that the superior canine is not so large as in the t ; 
saber-tooths. It certainly exceeds in this respect the other : 
nine. The present species is the largest saber-too of Nort | 
America, except perhaps the Sim/odon fatalis Leidy. The pe ? 
men on which it is based was found by Frank Hazard in Phil 
County, Kansas.—£. D. Cope. =
