  It 
  will 
  he 
  observed 
  that 
  I 
  unite 
  under 
  this 
  name 
  three 
  species 
  

   described 
  by 
  Bate 
  and 
  Westwood. 
  

  

  The 
  genus 
  Westicoodilla 
  was 
  established 
  under 
  a 
  misinter- 
  

   pretation 
  of 
  the 
  form 
  described. 
  The 
  first 
  gnathopods 
  were 
  

   not 
  observed 
  ; 
  the 
  second 
  gnathopods 
  were 
  regarded 
  as 
  the 
  

   first, 
  and 
  the 
  first 
  perteopods 
  as 
  the 
  second 
  gnathopods. 
  A 
  com- 
  

   parison 
  of 
  the 
  figures 
  published 
  by 
  Bate 
  and 
  Westwood 
  of 
  these 
  

   parts 
  with 
  those 
  here 
  given 
  will 
  show 
  this 
  to 
  have 
  been 
  the 
  

   case, 
  while 
  their 
  figures 
  d 
  and 
  g 
  (p. 
  155) 
  are 
  good 
  illustrations 
  

   of 
  the 
  mandible 
  and 
  maxillipeds 
  of 
  Halimedon 
  parvimanus, 
  

   the 
  palp 
  of 
  the 
  mandible 
  of 
  which 
  is 
  very 
  peculiar 
  and 
  unlike 
  

   that 
  of 
  any 
  other 
  species 
  known 
  to 
  me. 
  With 
  respect 
  to 
  W. 
  

   hyalina, 
  Bate 
  and 
  Westwood 
  themselves 
  questioned 
  its 
  dis- 
  

   tinctness 
  ; 
  it 
  was 
  taken 
  with 
  their 
  W. 
  ccecula, 
  and 
  I 
  can 
  see 
  

   no 
  specific 
  character 
  by 
  which 
  it 
  can 
  be 
  distinguished. 
  Their 
  

   (Edicer 
  os 
  parvimanus, 
  of 
  which 
  the 
  types 
  are 
  in 
  my 
  collection, 
  

   is 
  undoubtedly 
  the 
  Halimedon 
  MiiUeri 
  of 
  Boeek.
