process is more strongly notched. Following the margin of the 

 proximal end on each side is a ridge for ligament attachment. 



The margin of the ventral tuberosity is distinctly set off from 

 its middle convex portion. The osseous sheath is thinnest on 

 the sides. 



The terminal claw was retracted chiefly by a movement of 

 the entire digit upon the third metatarsal.
