  numerous 
  generic 
  divisions 
  proposed 
  by 
  him 
  would 
  doubtless 
  require 
  

   considerable 
  modification 
  in 
  any 
  general 
  systematic 
  arrangement 
  of 
  

   the 
  group. 
  Of 
  the 
  numerous 
  Australian 
  additions 
  to 
  this 
  Order 
  

   described 
  by 
  Haswell, 
  but 
  few 
  are 
  in 
  the 
  collections 
  received 
  from 
  

   Dr. 
  Coppinger, 
  

  

  1. 
  EpMppiphora 
  kroyeri, 
  White. 
  

  

  Several 
  small 
  specimens 
  from 
  Dundas 
  Straits, 
  17 
  fms. 
  (No. 
  161), 
  

   one 
  from 
  Prince 
  of 
  AVales 
  Channel, 
  7-9 
  fms., 
  and 
  one 
  from 
  Port 
  

   Denison, 
  4 
  fms. 
  (No. 
  122), 
  are 
  referred 
  to 
  this 
  species. 
  They 
  agree 
  

   with 
  White's 
  much 
  larger 
  types 
  in 
  the 
  form 
  of 
  the 
  body, 
  the 
  coxae 
  

   of 
  the 
  thoracic 
  legs, 
  and 
  particularly 
  in 
  the 
  great 
  development 
  of 
  the 
  

   postero-lateral 
  lobes 
  of 
  the 
  fourth 
  coxae, 
  in 
  the 
  broadly 
  rounded 
  

   basus-joints 
  and 
  somewhat 
  dilated 
  ischia 
  of 
  the 
  three 
  posterior 
  legs, 
  

   and 
  in 
  other 
  points. 
  White's 
  examples 
  (from 
  Tasmania) 
  are 
  dried, 
  

   and 
  the 
  first 
  and 
  second 
  legs 
  are 
  now 
  l)roken, 
  as 
  also 
  the 
  terminal 
  

   segment 
  in 
  both 
  specimens. 
  In 
  the 
  specimens 
  from 
  the 
  ' 
  Alert 
  ' 
  

   collection 
  the 
  terminal 
  segment 
  is 
  elongated, 
  narrowing 
  slightly 
  

   to 
  the 
  distal 
  extremit)-, 
  with 
  the 
  sides 
  straight, 
  and 
  is 
  divided 
  by 
  

   a 
  narrow 
  median 
  fissure 
  ; 
  the 
  imperfect 
  terminal 
  segments 
  in 
  

   White's 
  types 
  seem 
  to 
  show 
  a 
  similar 
  structure 
  ; 
  in 
  this 
  particular 
  

   they 
  differ 
  from 
  L. 
  nitens, 
  Haswell, 
  from 
  Port 
  Jackson. 
  L. 
  austra- 
  

   liensis, 
  Haswell, 
  has 
  a 
  very 
  close 
  resemblance 
  to 
  L. 
  kroi/eri, 
  and 
  I 
  

   should 
  have 
  considered 
  it 
  identical 
  with 
  it, 
  were 
  it 
  not 
  for 
  the 
  pro- 
  

   bable 
  difference 
  in 
  the 
  form 
  of 
  the 
  terminal 
  segment, 
  since 
  L. 
  austra- 
  

   lensis 
  is 
  only 
  distinguished 
  by 
  Haswell 
  from 
  L. 
  nitens 
  by 
  the 
  form 
  

   of 
  the 
  eyes 
  and 
  the 
  palms 
  and 
  fingers 
  of 
  the 
  second 
  legs. 
  

  

  In 
  the 
  present 
  uncertainty 
  as 
  to 
  the 
  true 
  limits 
  of 
  the 
  genera 
  of 
  

   this 
  group, 
  I 
  refer 
  to 
  this 
  species 
  under 
  White's 
  original 
  designation 
  

   Ejphijypiphora. 
  By 
  Boeck 
  this 
  genus 
  is 
  doubtfully 
  considered 
  to 
  be 
  

   identical 
  with 
  his 
  Socarnes, 
  first 
  described 
  in 
  1870.

  the 
  species 
  from 
  Dunedin, 
  New 
  Zealand 
  

   (as 
  Lysianassa 
  tcroi/eri) 
  ; 
  but 
  as 
  he 
  says 
  nothing 
  of 
  the 
  form 
  of 
  the 
  

   telson 
  or 
  terminal 
  segment, 
  I 
  am 
  not 
  sure 
  of 
  the 
  identity 
  of 
  his 
  

   specimens 
  with 
  the 
  true 
  kroyeri.
