  'In

  extend 
  a 
  litMe 
  more

  tip 
  of

  of 
  a 
  very 
  dift'crent 
  shape, 
  the 
  basal 
  third 
  gradually 
  and 
  normally 
  broadening, 
  

   but 
  beyond 
  tapering 
  rather 
  rapidly, 
  so 
  that 
  the 
  rounded 
  tip 
  is 
  narrower 
  than 
  the 
  

   base; 
  it 
  looks 
  like 
  an 
  abnormal 
  development.
