 surrounds the parts of the foot like a stocking, and upon which 

 the foot rests, as a shoe on the human foot. In this apparatus are 

 found: 1st, the coronary band, which forms a rounded projection

 which is spread upon the anterior face of the third phalanx, and

 analogous laminpe of the internal face of the wall (Figure 481) ;
