 periphery and above the periphery with a band 2.8 mm. wide, amber 

 brown above the aperture, the band is lined with mustard yellow, 

 and on the last half whorl breaks up into three bands of amber brown, 

 just behind the edge of the lip a streak of warm sepia, last whorl 

 below the periphery mustard yellow ; lip army brown streaked with 

 white ; columella callus army brown shading to white at the tip of the
