band, about 5 mm. wide, at the junction of the matrix and the 

 ordinary skin of the digit. Each end of the band is continuous with 

 the matrix covering the digital torus, and its surface is studded 

 with papillfB that are smaller than those of the adjacent part of 

 the matrix.

 adjacent to the foregoing, from which it is separated by a shallow
