This genus contains but one species, founded on several lower jaws
disinterred from the Wasatch beds in the Big-Horn Bad-lands, in Northern
Wyoming. The lower incisors, or perhaps, canines, are very large and close
to the line of union of the two halves of the jaw; the molars have three
cusps in front and a heel behind. The dental characters of the genus
"resemble considerably those of _Anaptomorphus_ and _Necrolemur_
[_Microchærus_] but the large size of the inferior canine {117}or incisor
tooth distinguishes it from both." (Cope.) C. LATIDENS, Cope, is the only
species.
