The disproportion in the size of the premolar and tubercular teeth 
strikingly distinguishes this species from those of the type of C. lupus. 
From C. liaydenii^ which is probably more nearly allied, it differs widely in 
the absence of the upward direction of the alveolar border, the excavation 
of the external face of the ramus, the one-rooted second tubercular molar, 
etc. It is not unlikely that when the superior molar dentition of C. haydenii 
is known, it will prove to be an AmpMajon.

Represented by a left mandibular ramus, which supported the molars 
to and including the anterior blade of the sectorial tooth. The premolars 
number three, and the first is one-rooted. The crowns of the second and 
third are simple, that is, Avithout posterior lobe; but they possess well- 
defined anterior and fAOsterior basal lobes, but no lateral cingula. The an¬ 
terior lobe of the sectorial is elongate and rather low; its edge is worn by 
long use, indicating the adult age of the animal. Enamel smooth, A deli¬ 
cate foramen mentale perforates the ramus below the second premolar, and 
another enters below the third. The ramus is shallow and moderately com¬ 
pressed.
