  The 
  two 
  dry 
  specimens 
  which 
  represent 
  this 
  species 
  have, 
  

   unfortunately, 
  neither 
  of 
  them 
  retained 
  their 
  original 
  base, 
  but 
  the 
  

   larger 
  one 
  was 
  broken 
  off 
  at 
  a 
  point 
  probably 
  not 
  far 
  above 
  it. 
  The 
  

   length 
  of 
  the 
  specimens 
  respectively 
  is 
  18|

  are
