Characters. — Nearly allied to the existing representatives of the group, 

 but with larger antlers. The species was founded on a skull showing the 

 simple anterior branch of the antlers, which curves upwards and forwards, 

 starting at right angles to the posterior branch, which is broken away on 

 both sides. The left frontlet and antler forming the type of F. sulcatus 

 does not appear to be specifically distinct. 



Remains of one or other of the existing species occur in the superficial 

 deposits of Ecuador. 



Distribution. — Argentina during the Plistocene epoch.
