  There 
  is 
  in 
  Dr. 
  Coppinger's 
  collection 
  a 
  small 
  female 
  from 
  Warrior 
  

   Reef, 
  Torres

  a 
  yet 
  smaller 
  male 
  from 
  Albany

  In 
  the 
  Museum 
  collection 
  is 
  

   an 
  adult 
  male 
  from 
  Torres 
  Straits 
  {Mr. 
  McFarlane). 
  I 
  cannot 
  

   identify 
  this 
  species 
  with 
  any 
  of 
  the 
  Australian 
  forms 
  described 
  

   by 
  Mr. 
  Haswell. 
  

  

  From 
  the 
  Pilumnus 
  bleel-eri, 
  recently 
  described 
  by 
  me 
  *, 
  which 
  

   inhabits 
  New 
  Giiinea, 
  and 
  which 
  this 
  species 
  somewhat 
  resembles 
  

   in 
  external 
  appearance, 
  it 
  is 
  distinguished 
  by 
  the 
  much 
  narrower 
  

   fissure 
  of 
  the 
  front, 
  different 
  spinulation 
  of 
  the 
  antero-lateral 
  

   margins, 
  and 
  the 
  three 
  sj)ines 
  on 
  the 
  upper 
  surface 
  of 
  the 
  palms 
  of 
  

   the 
  chelipedes. 
  

  

  In 
  Pihimmis 
  vestittis, 
  Haswell 
  (Cat. 
  p. 
  68), 
  from 
  Port 
  Jackson 
  

   and 
  Port 
  Stephens, 
  which 
  has 
  the 
  carapace 
  covered 
  with 
  stiff 
  yellow 
  

   hairs 
  as 
  in 
  P. 
  pulcJier, 
  the 
  surface 
  is 
  not 
  granulated, 
  and 
  the 
  spinu- 
  

   lation 
  of 
  the 
  carapace 
  and 
  chelipedes 
  is 
  different. 
  

  

  55. 
  Pilumnus 
  rufopunctatus, 
  Stimpson. 
  

  

  Three 
  specimens 
  (two 
  males 
  and 
  a 
  female) 
  were 
  obtained 
  at 
  Port 
  

   Jackson, 
  5-7 
  fms. 
  (No. 
  104). 
  

  

  Mr. 
  Haswell 
  records 
  it 
  from 
  Port 
  Stephens 
  and 
  Western 
  Port. 
  

  

  It 
  nearly 
  resembles 
  the 
  following 
  species 
  {P. 
  lamitus), 
  which 
  

   occurred 
  with 
  it, 
  but 
  is 
  distinguished 
  by 
  the 
  granulations 
  of 
  the 
  

   chelipedes 
  extending 
  over 
  the 
  whole 
  of 
  the 
  outer 
  surface 
  of 
  the 
  

   hand, 
  and 
  the 
  tuberculation 
  of 
  the 
  carapace, 
  which, 
  however, 
  seems 
  

   to 
  be 
  a 
  variable 
  character, 
  &:c. 
  

  

  Possibly 
  the 
  P. 
  riifojmnctaius 
  of 
  Stimpson 
  is 
  itself 
  to 
  be 
  identified 
  

   with 
  P. 
  tomentosus 
  of 
  Milne-Edwards. 
  This 
  is 
  a 
  point 
  which 
  cannot 
  

   be 
  satisfactorily 
  determined 
  from 
  the 
  very 
  brief 
  diagnosis 
  of 
  the 
  

   latter 
  author. 
  

  

  56. 
  Pilumnus 
  lanatus, 
  LatreUh 
  ? 
  (Plate 
  XXI. 
  fig. 
  B.) 
  

  

  As 
  the 
  P. 
  lanatus 
  has 
  been 
  only 
  very 
  bilefly 
  described, 
  and 
  the 
  

   identification 
  of 
  this 
  species 
  must 
  be 
  regarded 
  as 
  uncertain, 
  I 
  append 
  

   the 
  following 
  detailed 
  description 
  : 
  — 
  

  

  In 
  the 
  specimens 
  I 
  thus 
  designate 
  the 
  carapace 
  is 
  moderately 
  

   convex, 
  of 
  the 
  usual 
  shape, 
  and, 
  as 
  well 
  as 
  the 
  legs, 
  is 
  covered 
  with 
  

   a 
  short 
  dense 
  brown 
  pubescence, 
  which 
  is 
  absent 
  in 
  great 
  measure 
  

   from 
  the 
  inferior 
  surface 
  of 
  the 
  body 
  and 
  from 
  the 
  anterior 
  and
