  COLLECTIONS 
  FROM 
  MELANESIA. 
  

  

  distal 
  extremity 
  of 
  its 
  fourth 
  and 
  fifth 
  joints 
  five 
  protuberances, 
  

   of 
  which 
  the 
  two 
  outerinost 
  are 
  small, 
  and 
  the 
  three 
  inner 
  longer, 
  strong 
  

   and 
  subacute 
  ; 
  near 
  the 
  middle 
  of 
  the 
  ventral 
  surface 
  of 
  the 
  fourth 
  

   joint 
  is 
  a 
  small 
  process 
  (as 
  in 
  F. 
  Jluminense), 
  and 
  a 
  series 
  of 
  minute 
  

   spinules 
  or 
  protuberances 
  along 
  the 
  upper 
  margin 
  of 
  the 
  fifth 
  joint; 
  

   the 
  joints 
  also, 
  except 
  perhaps 
  the 
  eighth, 
  are 
  marked 
  with 
  longi- 
  

   tudinal 
  impressed 
  lines 
  ; 
  the 
  eighth 
  has 
  a 
  series 
  of 
  spinules 
  on 
  its 
  

   inferior 
  surface 
  ; 
  besides 
  the 
  terminal 
  claw 
  there 
  are, 
  as 
  already 
  

   noted, 
  two 
  strong 
  accessory 
  claws. 
  The 
  first 
  to 
  third 
  joints 
  of 
  the 
  

   legs 
  are 
  scantily 
  clothed 
  with 
  very 
  short 
  hair 
  ; 
  the 
  distal 
  protu- 
  

   berances 
  of 
  the 
  fourth 
  joint 
  and 
  the 
  fifth 
  joints 
  are 
  more 
  thickly 
  

   clothed 
  with 
  longer 
  hair, 
  and 
  the 
  sixth 
  to 
  eighth 
  joints 
  again 
  with 
  a 
  

   much 
  finer, 
  more 
  scanty 
  pubescence. 
  

  

  Three 
  specimens 
  are 
  in 
  the 
  collection, 
  obtained 
  respectively 
  at 
  

   Duudas 
  Straits, 
  17 
  fms. 
  (No. 
  161), 
  Thursday 
  Island, 
  4-5 
  fms. 
  (Xo. 
  

   165), 
  and 
  in 
  Prince 
  of 
  Wales 
  Channel, 
  7 
  fms. 
  (IN'o. 
  169). 
  As 
  in 
  

   these 
  specimens 
  the 
  thigh-joints 
  are 
  not 
  specially 
  dilated 
  and 
  the 
  

   geiiital 
  pores 
  are 
  small, 
  I 
  believe 
  them 
  to 
  be 
  males. 
  

  

  Tliis 
  species 
  resembles 
  Phoxichilklium 
  insir/ne, 
  Hoek 
  (t. 
  c. 
  p. 
  82, 
  

   pi. 
  xiv. 
  figs. 
  5-7), 
  from 
  Bahia, 
  in 
  the 
  curious 
  distal 
  protuberances 
  of 
  

   the 
  fourth 
  and 
  fifth 
  joints 
  of 
  the 
  legs, 
  but 
  these 
  are 
  absent 
  from 
  

   the 
  second 
  and 
  third 
  joints 
  in 
  P. 
  hoekii, 
  and 
  our 
  species 
  differs 
  in 
  

   many 
  other 
  most 
  important 
  points, 
  as 
  (e.g.) 
  in 
  the 
  closely 
  approxi- 
  

   mated 
  leg-bearing 
  processes 
  of 
  the 
  body, 
  the 
  terminally-placed 
  second 
  

   joints 
  of 
  the 
  mandibles, 
  and 
  the 
  more 
  robust 
  body 
  and 
  append- 
  

   ages. 
  The 
  first-mentioned 
  of 
  these 
  characters 
  will 
  also 
  separate 
  

   this 
  species 
  from 
  P. 
  Jluminense, 
  Kroyer 
  (see 
  Hock, 
  t. 
  c. 
  p. 
  81, 
  

   pi. 
  xiv. 
  figs. 
  1-4), 
  from 
  which 
  it 
  is 
  also 
  distinguished 
  by 
  the 
  

   distal 
  protuberances 
  of 
  the 
  leg-joints 
  &c. 
  The 
  existence 
  of 
  these 
  

   protuberances 
  separates 
  this 
  species 
  from 
  those 
  other 
  species 
  of 
  

   PlioxicliUidiimi 
  described 
  by 
  Dr. 
  Hoek 
  in 
  which 
  the 
  leg-bearing 
  

   processes 
  are 
  more 
  or 
  less 
  approximated, 
  and 
  from 
  the 
  two 
  Austral 
  

   species 
  described 
  by 
  White* 
  as 
  Nymphon 
  pJiasma 
  and 
  N.johnstonia- 
  

   num, 
  which 
  Dr. 
  Hoek 
  has 
  shown 
  belong 
  to 
  Phoxichilidmm. 
  The 
  

   "points" 
  mentioned 
  by 
  White 
  as 
  occurring 
  at 
  the 
  end 
  of 
  the 
  oints 
  

   in 
  N. 
  johnstonianum 
  are, 
  I 
  may 
  add, 
  only 
  short 
  stiff 
  sefce.
