﻿CRUSTACEA..

  One 
  specimen 
  (a 
  male) 
  was 
  obtained 
  at 
  Port 
  Molle, 
  14 
  fms. 
  

   (No. 
  93) 
  ; 
  in 
  the 
  second 
  collection 
  are 
  an 
  adult 
  female 
  and 
  two 
  

   smaller 
  specimens 
  from 
  Thursday 
  Island, 
  3-5 
  fms. 
  (Nos. 
  165, 
  177). 
  

  

  In 
  many 
  of 
  its 
  characters 
  this 
  species 
  resembles 
  P. 
  vespertiJio, 
  

   but 
  differs 
  in 
  the 
  curious 
  sculpture 
  and 
  less 
  dense 
  hairiness 
  of 
  the 
  

   carapace, 
  the 
  prominent 
  teeth 
  of 
  the 
  antero-lateral 
  margins, 
  and 
  the 
  

   existence 
  of 
  distinct 
  teeth 
  on 
  the 
  upper 
  margin 
  of 
  the 
  palm 
  (fig. 
  c). 
  

  

  In 
  the 
  very 
  remarkable 
  sculpture 
  of 
  the 
  carapace 
  it 
  somewhat 
  

   resembles 
  P. 
  vermiculaius, 
  A. 
  M.-Edwards*, 
  from 
  New 
  Caledonia 
  ; 
  

   but 
  in 
  that 
  species 
  the 
  vermiculations 
  are 
  much 
  less 
  numerous, 
  the 
  

   front 
  is 
  much 
  deflexed 
  and 
  in 
  a 
  continuous 
  line 
  with 
  the 
  upper 
  

   orbital 
  margin, 
  the 
  teeth 
  of 
  the 
  antero-lateral 
  margins 
  are 
  much 
  

   more 
  obtuse, 
  &c.

  Hero 
  is 
  referred, 
  though 
  with 
  some 
  hesitation, 
  a 
  fine 
  male 
  from 
  

   Port 
  ]\Iolle, 
  14 
  fms. 
  (No. 
  93) 
  ; 
  also 
  a 
  male 
  and 
  two 
  females 
  in 
  the 
  

   British-Museum 
  collection, 
  preserved 
  dry, 
  and 
  dredged 
  by 
  Mr. 
  Mac- 
  

   gillivraj' 
  in 
  1 
  7 
  fathoms 
  between 
  Percy 
  Island 
  and 
  the 
  mainland, 
  on 
  

   a 
  bottom 
  consisting 
  of 
  coarse 
  sand 
  and 
  shells. 
  M, 
  A. 
  Milne-Edwards 
  

   says 
  that 
  the 
  regions 
  of 
  the 
  carapace 
  in 
  his 
  unique 
  example 
  (obtained 
  

   at 
  the 
  island 
  of 
  Lifu) 
  are 
  distinct, 
  whereas 
  in 
  the 
  Australian 
  

   examples 
  I 
  have 
  before 
  me 
  scarcely 
  any 
  traces 
  of 
  the 
  intervening 
  

   depressions 
  exist 
  : 
  moreover 
  the 
  form 
  of 
  the 
  seriately 
  disposed 
  

   tubercles 
  of 
  the 
  outer 
  surface 
  of 
  the 
  chelipedes 
  is 
  very 
  peculiar 
  and 
  

   characteristic 
  ; 
  these 
  tubercles 
  are 
  separated, 
  indeed, 
  at 
  their 
  bases, 
  

   but 
  have 
  their 
  heads 
  dilated 
  and 
  in 
  contact 
  with 
  one 
  another, 
  and 
  

   the 
  heads 
  are 
  also 
  armed 
  (usually 
  on 
  one 
  side 
  only) 
  with 
  laterally 
  

   projecting 
  spinules. 
  This 
  disposition 
  cannot 
  be 
  seen 
  except 
  under 
  a 
  

   lens 
  of 
  considerable 
  power, 
  and 
  hence 
  may 
  have 
  been 
  unnoticed 
  by 
  

   M. 
  A. 
  Milne-Edwards. 
  

  

  Mr. 
  Haswell 
  gives 
  Darnley 
  Island 
  as 
  an 
  additional 
  Australian 
  

   locality 
  for 
  this 
  species.
