Eubrontes verv close! V, 



UICHARD SWANN LULL ON 



It IS distinguished from Eubrontes, however, by the presence 

 of the heel and the partly rotated hallux. When the 

 animal is walking and these two characters are not seen 

 it is very difficult to distinguish the two genera.

The posture of the animal is somewhat different from 

 that of Anomoepus for here the creature brings the hind 

 limbs more under the body so that very little weight is borne 

 on the hands as in the kangaroo. This makes a very Hght 

 and incomplete manus impression, no pads being discernible. 

 The claws are more slender in proportion to the width of the 

 fingers than in Anomoepus, probably correlated with their 

 slight use as supporting organs and consequent greater pre- 

 hensile function.
