  median 
  spines, 
  as 
  in 
  Stimpson's 
  description), 
  but 
  the 
  median 
  spine 
  is 
  

   itself 
  arcuated 
  and 
  very 
  distinctly 
  denticulated 
  on 
  the 
  lateral 
  mar- 
  

   gins 
  as 
  well 
  as 
  on 
  the 
  dorsal 
  surface, 
  and 
  there 
  are 
  two 
  spines 
  on 
  

   the 
  front 
  of 
  tlie 
  branchial 
  regions. 
  Nevertheless 
  a 
  sufficient 
  series 
  of 
  

   specimens 
  might 
  perhaps 
  hereafter 
  show 
  the 
  Australian 
  to 
  be 
  a 
  mere 
  

   variety 
  of 
  the 
  Japanese 
  form. 
  

  

  In 
  the 
  absence 
  of 
  the 
  supraocular 
  spines 
  these 
  species 
  resemble 
  

   the 
  American 
  genus 
  (or 
  subgenus) 
  Galathodes, 
  A. 
  M.-Edwards 
  *, 
  but 
  

   the 
  corneae 
  of 
  the 
  eyes 
  are 
  considerably 
  dilated, 
  and 
  the 
  dactyli 
  of 
  

   the 
  ambulatory 
  legs 
  (in 
  M. 
  spinulifera) 
  are 
  not 
  strongly 
  spinulose. 
  

   Of 
  all 
  the 
  numerous 
  American 
  species 
  of 
  Munida 
  described 
  by 
  A. 
  

   M.-Edwards 
  {t. 
  c. 
  pp. 
  47-52) 
  the 
  nearest 
  allies 
  to 
  M, 
  spinulifera 
  are 
  

   apparently 
  M. 
  iris 
  and 
  M. 
  irasa, 
  from 
  which 
  M. 
  spinulifera 
  is 
  dis- 
  

   tinguished 
  by 
  having 
  the 
  first 
  two 
  segmeats 
  of 
  the 
  postabdomen 
  

   armed 
  with 
  several 
  spimxles 
  &c.

  Seven 
  specimens 
  were 
  collected 
  in 
  Prince 
  of 
  Wales 
  Channel, 
  

   5-7 
  fms. 
  (No. 
  150), 
  which 
  scarcely 
  difter 
  from 
  the 
  type 
  from 
  the 
  

   Philippines 
  in 
  the 
  British-Museum 
  collection 
  except 
  in 
  having 
  the 
  

   median 
  frontal 
  lobes 
  generally 
  somewhat 
  more 
  acute. 
  A 
  careful 
  

   comparison 
  of 
  these 
  specimens 
  with 
  the 
  (previously) 
  unique 
  dried 
  

   type 
  example 
  shows 
  that 
  the 
  number 
  of 
  joints 
  in 
  the 
  terminal 
  fla- 
  

   gelliform 
  portion 
  of 
  the 
  anterior 
  limbs 
  (which 
  are 
  imperfectly 
  seen 
  

   on 
  account 
  of 
  the 
  hairs 
  with 
  which 
  they 
  are 
  thickly 
  clothed) 
  was 
  

   understated 
  in 
  the 
  original 
  description 
  ; 
  instead 
  of 
  being 
  ten 
  or 
  

   twelve, 
  they 
  are 
  usually 
  twice 
  as 
  numerous.

  Gebia 
  carinicauda, 
  Stimpson. 
  

  

  Two 
  females 
  are 
  in 
  the 
  collection 
  from 
  the 
  beach 
  at 
  Thursday 
  

   Island 
  (No. 
  167). 
  Another 
  in 
  the 
  British 
  Museum 
  was 
  collected 
  

   by 
  Mr. 
  MacFarlane 
  on 
  the 
  shores 
  of 
  one 
  of 
  the 
  islands 
  in 
  Torres 
  

   Straits. 
  Stimpson's 
  ty])es 
  were 
  from 
  Hong 
  Kong. 
  These 
  specimens 
  

   agree 
  very 
  well 
  with 
  Stimpson's 
  description, 
  except 
  that 
  the 
  upper 
  

   margins 
  of 
  the 
  dactyli 
  of 
  the 
  anterior 
  legs 
  can 
  scarcely 
  be 
  de- 
  

   scribed 
  as 
  carinatcd. 
  The 
  spinules 
  of 
  the 
  front 
  are 
  almost 
  com- 
  

   pletely 
  concealed 
  by 
  the 
  pubescence, 
  but 
  are 
  distinctly 
  visible 
  in 
  a 
  

   lateral 
  view. 
  

  

  In 
  a 
  smaller 
  specimen, 
  also 
  a 
  female 
  and 
  from 
  thd 
  same 
  locality, 
  

   the 
  spinules 
  mentioned 
  by 
  Stimpson 
  as 
  existing 
  above 
  the 
  genital 
  

   apertures 
  in 
  the 
  third 
  pair 
  of 
  legs 
  (and 
  which 
  are 
  very 
  distinct 
  in 
  

   the 
  larger 
  examples 
  in 
  the 
  ' 
  Alert 
  ' 
  collection) 
  are 
  not 
  developed.
