penultimate are still stouter in form. The ungues of the middle line are 

 symmetrical and broad, -with the margin a segment of an ovoid, and slight 

 contraction at the neck. The proximal articulation is bounded by a fossa 

 on each side, which is in its turn, isolated by the elongate process found 

 in the tapir and in the horse. The margin is marked by radiating striae 

 separated by grooves, of which the median is the most marked. The 

 latei-al ungues are contracted on the inner side, and only possess the 

 proximal fossa and hook on the outer side: The median distal groove is 

 well marked.
