groups in the disto-proximal direction. Fusion of pads IV, 

 H d and H p in the sole of Tarsius and other indications of 

 intimate linear aggregations of these pads, with correspond- 

 ing evidences involving Th, I and II, suggests a fundamental 

 significance of such groupings. Even deeper structures as- 

 sociated with the pads may exhibit comparable relationships. 

 The cartilage plates in Myopotamus, as described by Zucker- 

 kandl ('06), are blended into two sets, a radial group and an 

 ulnar group, corresponding to the thenar and hypothenar 

 groups of configurations here presented.
