  Margin 
  (fig.

  with 
  a 
  

   close 
  series 
  of 
  conspicuous 
  paired 
  pores, 
  terminating 
  at 
  some 
  distance 
  from 
  the 
  

   posterior 
  extremity, 
  which 
  is 
  demarked 
  by 
  a 
  curved 
  transverse 
  crease. 
  A 
  scattered 
  

   series 
  of

  extends 
  from

  spiracle 
  to 
  the

  along 
  

   the 
  margin 
  for 
  some 
  distance 
  on

  of 
  the

  but 
  absent 
  elsewhere.

  An

  double 
  paired

  The 
  absence 
  of 
  a 
  definite 
  setiferous 
  anal 
  ring 
  is 
  unusual 
  in 
  the 
  genus 
  Asterole- 
  

   canium, 
  but 
  this 
  condition 
  occurs 
  in 
  an 
  Australian 
  species 
  — 
  A. 
  hilli* 
  as 
  also 
  in 
  the 
  

   allied 
  genus 
  Polea.\ 
  In 
  A. 
  cerifemm\ 
  and 
  pudibundum§ 
  there 
  is 
  no 
  apparent 
  seti- 
  

   ferous 
  ring 
  ; 
  but 
  in 
  those 
  species 
  the 
  anal 
  tube 
  is 
  more 
  complex, 
  consisting 
  of 
  several 
  

   conspicuous 
  invaginations 
  of 
  the 
  rectum.
