^ In Hyracotheriutu proper, p* has but one cusp ; in all the American species, a trittocone 

 is also present. " It may yet be found that there are other important differences between these 

 groups which will necessitate recognizing a separate genus for the American forms, in which 

 event the name Eohippus, proposed by Marsh, would have to be adopted." Wortman, Bull.
