 Tlic oxti'vnal snrfatM! of the 

 wall is glossy, as thougli var- 

 nished ; its internal surfao** 

 is striated throughout, except 

 at the hollowed bevel at its 

 upper edge; the strijie of the 

 external face of the Avail 

 (horny laminjie, keraphyllous 

 tissue) are designed to work 

 into the fleshy laminae or po- 

 dophyllous tissue. The bevel 

 at the upper edge of the in- 

 ternal face of the wall, hol- 

 lowed like a groove, is de- 

 signed to receive the pad, and 

 is pierced with a number of 

 small openings, into which 

 penetrate the filaments of the 

 pad, which are true hair-cells.
