In the restoration of this species as given by Professor Cope 

 in the America^i Naturalist, Vol. XVI, Plate XVII, the skull used is 

 the male one here fio-ured, Avith the tusk much elong-ated. The lower jaw 

 below it belong-ed to a female, possibly of another g-enus. The scapula, 

 as restored, is unlike that of any of the known Dinocerata, and the entire 

 fore limb is in a position anatomically impossible.
