  Von 
  Martens

  incline 
  to 
  identify 
  this 
  species 
  with 
  A. 
  

   franlUnii; 
  Huxley 
  with 
  A. 
  s^mii/era. 
  It 
  seems 
  to 
  me 
  more 
  likely 
  that 
  

   it 
  is 
  a 
  valid 
  species, 
  the 
  Australian 
  representative 
  of 
  the 
  Tasmanian 
  A. 
  

   franldinii.

  Hahitat. 
  — 
  Paramatta 
  River, 
  Sydney, 
  Australia 
  (Bate). 
  

  

  Bate 
  described 
  this 
  species 
  from 
  a 
  single 
  female 
  specimen 
  94 
  mm. 
  

   (about 
  o| 
  inches) 
  long, 
  collected 
  by 
  the 
  "Challenger" 
  expedition. 
  Anta- 
  

   copsifi 
  spinifera 
  was 
  collected 
  at 
  the 
  same 
  place 
  (Paramatta 
  River, 
  Syd- 
  

   ney), 
  and 
  I 
  am 
  inclined 
  to 
  think 
  that 
  A. 
  paramattensis 
  is 
  nothing 
  but 
  a 
  

   young, 
  small 
  specimen 
  of 
  A. 
  spinifera. 
  It 
  can 
  be 
  demonstrated 
  that 
  

   among 
  the 
  Farastacina\ 
  as, 
  for 
  instance, 
  in 
  the 
  genus 
  Faranephrops., 
  

   the 
  heavy 
  armature 
  of 
  si)ines 
  or 
  tubercles 
  may 
  be 
  acquired 
  only 
  by 
  

   large 
  individuals, 
  long 
  after 
  sexual 
  maturity 
  has 
  been 
  reached.
