  the 
  dactyli 
  well 
  developed 
  and 
  impinging 
  against 
  the 
  produced 
  

   scabrous 
  infero-distal 
  lobe 
  of 
  the 
  preceding 
  joint. 
  The 
  postabdomen 
  

   (in 
  the 
  female) 
  has 
  on 
  its 
  left 
  side 
  three 
  appendages, 
  articulated 
  

   with 
  as 
  many 
  membranaceous 
  dorsal 
  plates, 
  and 
  each 
  terminating 
  

   in 
  four 
  filaments 
  or 
  tiagella, 
  which 
  are 
  clothed 
  with 
  long 
  hairs. 
  The 
  

   uropods 
  on 
  one 
  side 
  are 
  imperfect, 
  their 
  rami 
  ^e 
  margined 
  with 
  

   rather 
  long 
  hairs 
  ; 
  the 
  segment 
  with 
  which 
  they 
  are 
  articulated 
  has 
  

   a 
  longitudinal 
  groove 
  on 
  its 
  dorsal 
  surface. 
  The 
  coloration 
  (which 
  

   is 
  probably 
  faded 
  in 
  both 
  the 
  specimens 
  examined) 
  is 
  yellowish 
  or 
  

   whitish, 
  with 
  very 
  faint 
  pink 
  reticulations 
  in 
  the 
  larger 
  specimen 
  ; 
  

   the 
  chelae 
  are 
  pink, 
  the 
  eye-peduncles 
  bordered 
  on 
  the 
  sides 
  with 
  

   broad 
  longitudinal 
  bands' 
  of 
  brownish 
  pink; 
  the 
  under 
  and 
  inner 
  

   surfaces 
  of 
  the 
  last 
  two 
  joints 
  of 
  the 
  second 
  and 
  third 
  legs 
  are 
  of 
  

   the 
  same 
  colour. 
  The 
  length 
  of 
  the 
  carapace 
  (in 
  the 
  larger 
  speci- 
  

   men) 
  is 
  about 
  1 
  inch 
  5 
  lines 
  (37millim.), 
  the 
  length 
  of 
  the 
  third 
  

   (right) 
  leg 
  exceeds 
  3| 
  inches 
  (90 
  millim.) 
  ; 
  but 
  the 
  specimen 
  being 
  

   dried, 
  its 
  exact 
  dimensions 
  cannot 
  be 
  given. 
  

  

  Of 
  this 
  species 
  a 
  rather 
  small 
  adult 
  female 
  was 
  taken 
  in 
  the 
  

   Arafura 
  Sea, 
  32-36 
  fms. 
  (No. 
  160). 
  A 
  much 
  larger 
  female, 
  in 
  mu- 
  

   tilated 
  condition, 
  wanting 
  the 
  postabdomen, 
  is 
  among 
  the 
  Banksian 
  

   specimens 
  in 
  the 
  British-Museum 
  collection, 
  from 
  which 
  the 
  descrip- 
  

   tion 
  is 
  mainly 
  taken. 
  

  

  This 
  species 
  resembles 
  Clibanarius, 
  and 
  differs 
  from 
  most 
  species 
  

   of 
  Fagurus 
  in 
  the 
  subequal 
  spinulose 
  chelipedes 
  ; 
  in 
  the 
  structure 
  

   of 
  the 
  ophthalmic 
  segment 
  of 
  the 
  eyes, 
  the 
  absence 
  of 
  a 
  rostrum, 
  

   and 
  in 
  other 
  points 
  it 
  is 
  a 
  true 
  Pagurus. 
  In 
  P. 
  platytliorax, 
  Stm., 
  a 
  

   species 
  with 
  equal 
  chelipedes, 
  the 
  chelae 
  and 
  legs 
  are 
  not 
  spinulose. 
  

  

  The 
  Pagurus 
  minutus, 
  Hess 
  (vide 
  Haswell, 
  Cat. 
  p. 
  156), 
  from 
  

   Sydney, 
  is 
  too 
  briefly 
  described 
  for 
  certain 
  identification, 
  but 
  seems 
  

   to 
  be 
  distinguished 
  from 
  P. 
  rubrovittatus 
  by 
  the 
  shorter 
  antennal 
  

   appendages 
  and 
  tubercidated 
  non-spinuliferous 
  chelipedes.

  A 
  single 
  male 
  was 
  obtained 
  at 
  Port 
  Molle, 
  inhabiting 
  a 
  shell 
  of 
  a 
  

   species 
  of 
  Purpura. 
  Another 
  specimen, 
  presenting 
  a 
  precisely 
  

   similar 
  system 
  of 
  coloration, 
  is 
  in

  British-Museum 
  collection

  These 
  specWens 
  agree 
  with 
  the 
  figure 
  of 
  Quoy 
  and 
  Gaimard, 
  and 
  

   diff'er 
  from 
  the 
  sjOimens 
  referred 
  to 
  C. 
  vulgaris 
  in 
  the 
  collection 
  of 
  

   the 
  British 
  Museum, 
  in 
  having 
  the 
  carapace 
  (as 
  well 
  as 
  the 
  ambu- 
  

   latory 
  legs) 
  marked 
  with 
  longitudinal 
  pale 
  lines 
  bordered 
  with 
  red 
  : 
  

   in 
  the 
  specimens 
  referred 
  to 
  P. 
  vulgaris 
  this 
  coloration 
  does 
  not 
  exist 
  

   upon 
  the 
  carapace; 
  the 
  eye-peduncles 
  are 
  somewhat 
  longer 
  and
