the scaly skin of the tarsus is continued up to it. Without 
taking the leg to pieces, or at least soaking and softening the 
parts, it is impossible to say, confidently, how this departure 
from the ordinary form is to be explained. It will probably 
turn out that this is a somewhat parallel case to the extra toe 
which we see in Dorking fowls, though why the toe has grown 
as it has, instead of in its proper place, below the tarsal joint, 
is difficult to explain.
