The crowns of all the incisor teeth are narrow or compressed, 
and, though slightly worn, present no indication of notch. As 
usual, the external ones are much the largest in antero-posterior 
diameter. The canines have robust fangs and rapidly tapering 
crowns, which are but little compressed. The first superior pre- 
molar is one-rooted, and the crown is simple. The crown of the 
second is without posterior heel and tubercle, while the third pos- 
sesses both. The sectorial is relatively short, less so than in C. 
latrans. The blades are low and obtuse as compared with receht 
species, and the notch separating them is quite open. The ante- 
rior external heel is small, and there is no anterior external tuber- 
cle. The first tubercular molar is large, and the crown is nar- 
rower than that of C.latrans. It has an obtuse external cingulum, 
two external conical cusps, a V-shaped median ridge, and a wide 
internal cingulum. This crown differs from the corresponding one 
of C. latrans in having conical instead of compressed external 
cusps, and a simple V-shaped crest within instead of two adjacent _ 
cusps. The second tubercular is smaller than in C. latrans, and 
its tubercles are less distinct. There are two outer tubercles, a 
V-shaped ridge, and an inner cingulum, all very obscure. The 
enamel of all these teeth is smooth.
