  the

  lead 
  one 
  to

  Accompanying 
  the 
  ductus 
  from 
  the 
  seminal 
  

   vesicle 
  towards 
  the 
  preputial 
  sac 
  are 
  two 
  enigmatic 
  structures, 
  one 
  on 
  each 
  side. 
  The 
  

   preputial 
  sac 
  is 
  large 
  when 
  expanded, 
  its 
  surface 
  covered 
  with 
  minute 
  recurved 
  

   denticles.

  The 
  basal

  is 
  elongate, 
  the 
  strongly 
  

   chitinised 
  lateral 
  margins 
  curving 
  in 
  towards 
  each 
  other. 
  The 
  paramera 
  are 
  long 
  and 
  

   curve 
  gracefully 
  outwards 
  at 
  the 
  tip.

  Tjasal

  Each 
  of 
  the 
  side-pieces 
  (or 
  lateral 
  

   margins) 
  of 
  the 
  basal-plate 
  sends 
  forward 
  beneath 
  the 
  articulation 
  of 
  each 
  para- 
  

   meron 
  a 
  narrower 
  piece 
  which, 
  meeting 
  its 
  fellow 
  in 
  the 
  middle 
  line, 
  runs 
  forward 
  

   with 
  it 
  without 
  fusing 
  to 
  the 
  base 
  of 
  the 
  preputial 
  sac, 
  a 
  deep 
  groove 
  lying 
  between 
  

   them 
  ; 
  they 
  perhaps 
  represent 
  the 
  telomera. 
  Distally 
  they 
  fade 
  away 
  into 
  the 
  mem- 
  

   brane 
  of 
  the 
  sac. 
  The 
  endomera 
  are 
  well 
  developed, 
  resembling 
  the 
  paramera 
  in 
  

   form, 
  and 
  are 
  articulated 
  below 
  the 
  latter 
  to 
  the 
  basal 
  plate.
