  of 
  the 
  legs 
  of 
  the 
  first 
  pair, 
  but 
  none 
  on 
  the 
  second 
  and 
  third 
  

   pairs 
  of 
  k>gs 
  ; 
  the 
  fifth 
  legs 
  are 
  scarcely 
  longer 
  than 
  the 
  fourth; 
  

   and 
  the 
  dactyli, 
  in 
  both 
  pairs, 
  about 
  eijiial 
  the 
  penultimate 
  joint 
  in 
  

   length. 
  The 
  rami 
  of 
  the 
  uropoda 
  are 
  rather 
  narrow 
  ovate, 
  and 
  longer 
  

   than 
  the 
  terminal 
  segment, 
  slightly 
  pubescent 
  above 
  and 
  with 
  long 
  

   ciliated 
  margins.

  Cerf 
  Island, 
  10 
  fms. 
  (No. 
  232) 
  ; 
  two 
  males. 
  

  

  The 
  description 
  is 
  taken 
  from 
  the 
  largest 
  specimen. 
  

  

  This 
  species 
  is 
  distinguished 
  from 
  most 
  of 
  its 
  congeners 
  by 
  the 
  

   form 
  and 
  extreme 
  brevity 
  of 
  the 
  rostrum, 
  the 
  armature 
  of 
  the 
  

   terminal 
  segment, 
  &c. 
  

  

  Prom 
  P.'i 
  podoplitludmus, 
  Stimpson, 
  from 
  Hong 
  Kong*, 
  it 
  is 
  at 
  

   once 
  distinguished 
  by 
  the 
  length 
  of 
  the 
  eye-peduncles 
  and 
  an- 
  

   tennules. 
  

  

  It 
  is 
  apparently 
  allied 
  to 
  P. 
  palmensis, 
  Haswell, 
  from 
  Palm 
  Island, 
  

   which 
  has, 
  however, 
  a 
  longer 
  rostrum 
  with 
  more 
  numerous 
  teeth, 
  

   the 
  second 
  to 
  sixth 
  segments 
  of 
  the 
  postabdomen 
  carinated, 
  &c. 
  

  

  There 
  are 
  in 
  the 
  collection 
  three 
  small 
  specimens 
  of 
  a 
  species 
  of 
  

   this 
  genus, 
  also 
  obtained 
  at 
  Cerf 
  Island 
  with 
  P. 
  riclitersii, 
  which 
  I 
  

   refrain 
  at 
  present 
  from 
  designating 
  by 
  a 
  distinct 
  specific 
  name, 
  

   although 
  I 
  cannot 
  refer 
  them 
  to 
  any 
  described 
  species. 
  The 
  body 
  

   is 
  everywhere 
  covered 
  with 
  a 
  short 
  hispid 
  pubescence. 
  The 
  rostrum 
  

   is 
  short 
  and 
  slender 
  and 
  acute, 
  scarcely 
  reaches 
  beyond 
  the 
  eyes, 
  and 
  

   is 
  armed 
  above 
  with 
  five 
  teeth, 
  whereof 
  the 
  first 
  is 
  separated 
  by 
  a 
  

   wider 
  interval 
  and 
  is 
  placed 
  on 
  the 
  gastric 
  region, 
  the 
  second 
  tooth 
  

   on 
  the 
  postfrontal 
  region, 
  just 
  behind 
  the 
  anterior 
  margin 
  of 
  the 
  

   carapace 
  ; 
  the 
  second 
  to 
  sixth 
  segments 
  of 
  the 
  body 
  are 
  carinated 
  

   (as 
  in 
  P. 
  palmensis) 
  ; 
  on 
  the 
  sixth 
  segment 
  the 
  carina 
  terminates 
  in 
  

   a 
  small 
  spinule. 
  Prom 
  P. 
  riclitersii 
  they 
  seem 
  to 
  be 
  distinguished 
  

   by 
  the 
  much 
  slenderer, 
  more 
  acute, 
  and 
  longer 
  rostrum, 
  and 
  the 
  

   longer 
  carina 
  of 
  the 
  postabdomen 
  ; 
  and 
  from 
  P. 
  palmensis, 
  Haswell, 
  

   with 
  which, 
  however, 
  they 
  may 
  prove 
  to 
  be 
  identical, 
  by 
  the 
  fewer 
  

   rostral 
  teeth, 
  &c.
