pad (pulv.phix-mt'carp.) of the polydactyle is five-lobed 
instead of three-lobed as normally, and the lobes in the 
polydactyle paw are more clearly marked off from one another 
than in the normal paw. The parts of the five-lobed pad 
which appear to correspond to the phalango-metacarpal pad 
of the normal paw are the three external lobes which are 
more closely associated with one another than with the two 
internal lobes; while the two internal lobes are more closely 
applied to each other than to the three external ones. That

five lobes instead of three existed in the polydactyle paw is 
probably due to the fact that one lobe was added by the for- 
mation of an extra digit, and that the growth of the radial 
digit, which occurred to so unusual an extent that it func- 
tioned more like a walking digit than the pollex normally 
does, excited the growth of a phalango-metacarpal pad on 
this digit also. In both the normal and the polydactyle paw 
there is a walking pad on the distal end of each middle pha- 
lanx (pulv.phix.) and on the pisiform bone (pulv.pis.).
