  The 
  rami 
  of 
  the 
  uropoda 
  are 
  somewhat 
  longer 
  than 
  the 
  terminal 
  

   segment, 
  ovate, 
  the 
  outer 
  somewhat 
  broader 
  than 
  the 
  inner. 
  Colour 
  

   (in 
  spirit) 
  purplish 
  brown. 
  Length 
  about 
  7| 
  lines 
  (16 
  millim.). 
  

  

  The 
  single 
  specimen, 
  a 
  female 
  with 
  ova, 
  was 
  obtained 
  at 
  Thursday- 
  

   Island, 
  4-0 
  fms. 
  (No. 
  130), 
  and 
  is 
  in 
  very 
  imperfect 
  condition, 
  the 
  

   right 
  chelipede 
  of 
  the 
  first 
  and 
  second 
  pair 
  and 
  most 
  of 
  the 
  ambula- 
  

   tory 
  legs 
  being 
  deficient. 
  Nevertheless 
  the 
  species 
  may 
  be 
  distin- 
  

   guished 
  from 
  all 
  described 
  by 
  Dana, 
  Heller, 
  or 
  Stimpson 
  by 
  the 
  

   difi'erent 
  dentition 
  of 
  the 
  rostrum. 
  On 
  account 
  of 
  the 
  minute 
  dactyl 
  

   with 
  its 
  inferior 
  tooth 
  I 
  refer 
  this 
  species 
  to 
  Cor 
  alii 
  ocaris 
  ; 
  but 
  it 
  

   differs 
  from 
  the 
  typical 
  species 
  in 
  the 
  slenderer 
  maxillipedes 
  and 
  

   shorter 
  antenna! 
  scales. 
  

  

  15. 
  Palsemon 
  (Leander) 
  intermedius, 
  Stimi^son. 
  

  

  Three 
  specimens, 
  two 
  of 
  which 
  are 
  females 
  with 
  ova, 
  were 
  obtained 
  

   at 
  Port 
  Jackson, 
  0-5 
  fms. 
  (first 
  collection). 
  8timpson's 
  specimens 
  

   were 
  also 
  from 
  Port 
  Jackson. 
  

  

  Specimens 
  are 
  in 
  the 
  British-Museum 
  collection 
  from 
  King 
  

   George's 
  Sound, 
  S.W. 
  Australia, 
  and 
  from 
  Ovalau, 
  Fiji 
  group 
  

   {F. 
  M. 
  Rayner, 
  H.M.S. 
  ' 
  Herald 
  '), 
  and 
  also 
  from 
  Tasmania. 
  

  

  This 
  species 
  usually 
  has 
  eight 
  teeth 
  above 
  and 
  five 
  below, 
  ex- 
  

   clusive 
  of 
  the 
  subapical 
  tooth 
  on 
  the 
  rostrum, 
  and 
  more 
  rarely 
  seven 
  

   above 
  and 
  four 
  below, 
  as 
  stated 
  by 
  Stimpson. 
  The 
  apex 
  is 
  usually, 
  

   but 
  not 
  invariably, 
  bidentate 
  ; 
  in 
  one 
  of 
  the 
  specimens 
  from 
  Port 
  

   MoUe 
  the 
  subapical 
  tooth 
  is 
  placed 
  further 
  back 
  on 
  the 
  dorsal 
  

   surface 
  of 
  the 
  rostrum, 
  which 
  thus 
  appears 
  simple 
  at 
  its 
  apex. 
  

   There 
  is 
  a 
  small 
  spine 
  at 
  the 
  base 
  of 
  the 
  antennal 
  peduncles 
  outside 
  

   of 
  the 
  antennal 
  scale. 
  

  

  I 
  regard 
  the 
  Palcvmon 
  (^Leander) 
  serenus 
  of 
  Heller*, 
  from 
  Sydney, 
  

   as 
  very 
  probably 
  a 
  mere 
  variety 
  of 
  P. 
  intermedius. 
  Mr. 
  Haswell 
  

   (Cat. 
  p. 
  195) 
  retains 
  the 
  two 
  species 
  as 
  distinct 
  ; 
  but 
  he 
  appears 
  to 
  

   have 
  seen 
  no 
  specimens, 
  and 
  his 
  translated 
  descriptions 
  are 
  in- 
  

   accurate 
  as 
  regards 
  the 
  second 
  pair 
  of 
  legs 
  in 
  both 
  species. 
  

  

  16. 
  Sicyonia 
  ocellata, 
  Stimpson. 
  

  

  A 
  small 
  specimen 
  is 
  in 
  the 
  second 
  collection, 
  from 
  Thursday- 
  

   Island, 
  4-5 
  fms. 
  (No. 
  165), 
  which 
  agrees 
  with 
  Stimpson's 
  descrip- 
  

   tion 
  and 
  the 
  specimens 
  in 
  the 
  British-Museum 
  collection 
  from 
  Ceylon 
  

   and 
  Hong 
  Kong. 
  To 
  this 
  species 
  also 
  belongs, 
  I 
  think, 
  the 
  Sicyonia 
  

   briefiy 
  characterized 
  by 
  Mr. 
  Haswell, 
  but 
  without 
  specific 
  name, 
  

   from 
  Port 
  Jackson 
  (vide 
  Cat. 
  p. 
  205). 
  

  

  17. 
  Penaeus 
  granulosus, 
  Hasivell. 
  

  

  A 
  small 
  male 
  from 
  Port 
  Darwin, 
  12 
  fms. 
  (first 
  collection), 
  belongs 
  

   here, 
  and 
  also, 
  I 
  think, 
  a 
  male 
  specimen 
  from 
  Thursday 
  Island,
