This animal will be fully described and figured in a later 

 publication. The above is intended merely as a preliminary 

 notice. Orthocynodon may be briefly described as an Eocene 

 perissodactyle LJngulate with the premolar-molar dentition of a 

 Rhinoceros, and somewhat resembling Amynodon in the posses- 

 sion of canines and loss of the medi.-in incisors. It has little of 

 the rhinocerotic character in the skull, but the resemblances 

 in the dentition points it out as related to Amynodon, with 

 which it belongs, among the group of Eocene progenitors of 

 the Rhinocerotidffi.
