5246. The proximal phalanx of the right minimus.

5249. The second phalanx of the right medius. 



5250. .The second phalanx of the right annularis.

These phalanges are shorter, less bent, and less expanded at the middle, than in the 

 Chimpanzee. 



5252. The ungual phalanx of the right index. 



5253. The ungual phalanx of the right medius. 



5254. The ungual phalanx of the right annularis. 



5255. The ungual phalanx of the right minimus. 



These are more expanded at their extremities than in the Chimpanzee.

The Human characteristics are strongly marked in this part of the skeleton. The ilium is 

 broader than it is long, and is more concave anteriorly, than in the Chimpanzee ; it is also 

 more concave posteriorly, especially in the vertical direction, in which it is slightly convex in 

 the Chimpanzee. The sacro-iliac symphysis is subquadrate, broader than it is long, instead 

 of being long and narrow as in the Chimpanzee. The labrum is much thicker and much 

 more curved ; and both angles, but especially the posterior one, are much more produced. 

 These modifications relate chiefly to the needful increased surface of attachment for the 

 large muscles which sustain the trunk upright upon the hinder, now become the lower, limbs.
