  The 
  vagina 
  is 
  lined 
  by 
  a 
  very 
  tall 
  epithelium 
  and 
  this 
  is 
  surrounded 
  

   by 
  a 
  wide 
  halo 
  of 
  what 
  seems 
  to 
  be 
  mesenchyme 
  traversed 
  by 
  radial 
  

   muscles. 
  Distally 
  the 
  vagina 
  narrows 
  to 
  a 
  short 
  tube 
  that 
  joins 
  the 
  

   male 
  antrum, 
  forming 
  a 
  very 
  small 
  common 
  antrum 
  that 
  opens 
  below 
  

   by 
  the 
  common 
  gonopore. 
  The 
  entrance 
  of 
  the 
  ovovitelUne 
  duct 
  

   into 
  the 
  copulatory 
  apparatus 
  could 
  not 
  be 
  found 
  but 
  presumably 
  

   this 
  duct 
  opens 
  into 
  the 
  roof 
  of 
  the 
  male 
  antrum. 
  In 
  the 
  posterior 
  

   wall 
  of 
  the 
  male 
  antrum 
  is 
  found 
  an 
  area 
  of 
  cyanophilous 
  glands 
  

   similar 
  to 
  those 
  surrounding 
  the 
  ejaculatory 
  duct 
  in 
  the 
  penis 
  papilla. 
  

  

  Differential 
  diagnosis. 
  — 
  Speophila 
  hoffmasteri 
  is 
  distinguished 
  from 
  

   the 
  other 
  known 
  species 
  of 
  the 
  gerus 
  by 
  the 
  round, 
  thick- 
  walled 
  

   vagina 
  and 
  the 
  layer 
  of 
  gland 
  tissue 
  in 
  the 
  penis 
  papilla 
  and 
  wall 
  of 
  

   the 
  male 
  antrum.
