  inner 
  ramus 
  of 
  the 
  uropoda, 
  have 
  the 
  external 
  genital 
  appendages 
  

   proper 
  to 
  the 
  male 
  sex, 
  which 
  are 
  not 
  to 
  be 
  found 
  on 
  any 
  of 
  the 
  

   specimens 
  I 
  regard 
  as 
  the 
  females 
  of 
  this 
  species, 
  several 
  of 
  which, 
  

   on 
  the 
  contrary, 
  carry 
  ova. 
  In 
  several 
  instances 
  I 
  have 
  found 
  the 
  

   two 
  forms 
  associated 
  in 
  the 
  same 
  phial 
  in 
  the 
  Museum 
  collection. 
  

  

  I 
  refer 
  to 
  this 
  species 
  the 
  following 
  females 
  in 
  the 
  ' 
  Alert 
  ' 
  collec- 
  

   tion, 
  which 
  may, 
  however, 
  belong 
  to 
  the 
  variety 
  crassicaudata, 
  

   Has 
  well 
  :

  An 
  adult 
  example 
  from 
  Port 
  Jackson, 
  5-7 
  fms. 
  (No. 
  104), 
  whence 
  

   also 
  Mr. 
  Haswell 
  records 
  it 
  as 
  Cymodocea 
  pubescens 
  ; 
  also 
  one 
  from 
  

   Thursday 
  Island, 
  4-5 
  fms. 
  (No. 
  165). 
  These 
  specimens 
  have 
  the 
  

   outer 
  ramus 
  of 
  the 
  uropoda 
  acute, 
  with 
  a 
  strong 
  tooth 
  on 
  its 
  outer 
  

   margin, 
  and 
  closely 
  resemble 
  S. 
  jnibescens 
  as 
  described 
  by 
  Milne- 
  

   Edwards. 
  

  

  Smaller 
  specimens 
  are 
  in 
  the 
  collection 
  from 
  Port 
  Curtis, 
  7 
  fms., 
  

   and 
  Albany 
  Island, 
  3-4 
  fms., 
  which 
  have 
  the 
  body 
  less 
  pubescent 
  

   and 
  the 
  postabdomen 
  more 
  distinctly 
  granulated, 
  the 
  rami 
  of 
  the 
  

   uropoda 
  somewhat 
  shorter, 
  the 
  outer 
  ramus 
  subacute 
  or 
  even 
  obtuse, 
  

   with 
  the 
  tooth 
  on 
  its 
  outer 
  margin 
  very 
  faintly 
  defined 
  or 
  obsolete. 
  

  

  The 
  rounded 
  elevations 
  on 
  the 
  upper 
  surface 
  of 
  the 
  terminal 
  

   segment 
  vary 
  much 
  in 
  prominence 
  in 
  this 
  species. 
  In 
  two 
  females 
  

   from 
  King 
  George's 
  Sound, 
  West 
  Australia, 
  which 
  may 
  belong 
  to 
  a 
  

   distinct 
  species, 
  they 
  are 
  very 
  prominent, 
  conical, 
  and 
  subacute. 
  

   An 
  approach 
  to 
  this 
  form 
  is, 
  however, 
  exhibited 
  in 
  one 
  of 
  Leach's 
  

   types 
  (a 
  male). 
  

  

  A 
  good 
  series 
  of 
  both 
  sexes 
  of 
  Ciliccea 
  latreillei 
  from 
  the 
  Australian 
  

   seas 
  is 
  in 
  the 
  British 
  Museum 
  from 
  the 
  collection 
  of 
  the 
  late 
  

   Dr. 
  J. 
  S. 
  Bowerbauk. 
  Unfortunately 
  the 
  exact 
  locality 
  has 
  not 
  been 
  

   preserved. 
  

  

  Mr. 
  Thomson 
  * 
  has 
  described 
  a 
  species 
  of 
  this 
  genus 
  (as 
  I 
  think) 
  

   from 
  Dunedin, 
  New 
  Zealand, 
  under 
  the 
  name 
  of 
  Nasea 
  ccmicidata, 
  

   which 
  is 
  allied 
  to 
  0. 
  latreillei, 
  but 
  distinguished 
  by 
  the 
  broadly 
  

   truncated 
  process 
  of 
  the 
  first 
  postabdominal 
  segment. 
  

  

  11. 
  Cilicsea 
  latreillei, 
  var. 
  crassicaudata 
  (Haswell). 
  

  

  A 
  male 
  and 
  female 
  are 
  in 
  the 
  collection 
  from 
  the 
  Arafura 
  Sea, 
  

   32-36 
  fms. 
  (No. 
  160), 
  and 
  also 
  a 
  male 
  and 
  two 
  females 
  without 
  

   special 
  indication 
  of 
  locality 
  (No. 
  123). 
  

  

  This 
  form 
  comes 
  extremely 
  near 
  to 
  Ciliccjea 
  latreillei, 
  Leach, 
  and 
  

   must, 
  I 
  think, 
  be 
  considered 
  a 
  mere 
  variety 
  of 
  it. 
  It 
  is 
  distinguished 
  

   by 
  the 
  longer, 
  less 
  conical 
  median 
  process 
  of 
  the 
  penultimate 
  post- 
  

   abdominal 
  segment, 
  and 
  the 
  much 
  longer 
  outer 
  ramus 
  of 
  the 
  uro- 
  

   poda, 
  which 
  is 
  not 
  toothed 
  on 
  its 
  outer 
  margin, 
  

  

  I 
  have 
  observed 
  males 
  of 
  the 
  typical 
  form 
  in 
  which 
  the 
  tooth 
  on 
  

   the 
  outer 
  margin 
  of 
  the 
  outer 
  uropod 
  is 
  obsolete.
