No species is given in the original reference; Scott & Osborn (loc. cit.) give two 
species from the Uinta formation, Utah, Zpihippus wintensis Marsh, and E. 
gracilis Marsh, referring the first to a separate of Marsh’s paper from the Proc. 
Am. Assoc., p. 24. [The species has not been found in the copy of the sepa- 
rate examined. ] 
“Epihippus might by some be considered to be preoccupied by Ephippus [Cuvier, 
1829], a genus of fishes; but in my opinion all the names should be retained 
as they are (if there is no other objection), on the assumption that more con- 
fusion would result from sacrifice of priority than of classical excellence."
