  Shark

  (H.M.S. 
  ' 
  Herald 
  ') 
  ; 
  the 
  emaller 
  specimen, 
  which 
  is 
  

   referable 
  to 
  the 
  variety 
  I 
  have 
  designated 
  Icevimana, 
  is 
  not 
  pitted 
  

   at 
  all, 
  and 
  the 
  carapace 
  is 
  granulated 
  only 
  on 
  the 
  posterior 
  part 
  of 
  

   the 
  cardiac 
  region, 
  on 
  the 
  elevated 
  parts 
  of 
  the 
  branchial 
  regions, 
  

   and 
  on 
  the 
  posterior 
  and 
  postero-lateral 
  margins. 
  

  

  Mr, 
  Haswell 
  records 
  a 
  variety 
  from 
  Port 
  Jackson 
  which 
  has 
  the 
  

   carapace 
  ornamented 
  with 
  numerous 
  small 
  circular 
  brown 
  spots. 
  In 
  

   the 
  specimens 
  I 
  have 
  examined 
  the 
  carapace 
  is 
  generally 
  uniformly 
  

   pinkish 
  or 
  whitish 
  ; 
  but 
  in 
  the 
  largest 
  male 
  from 
  Thursday 
  Island 
  it 
  

   is 
  whitish, 
  with 
  a 
  few 
  large 
  blotches 
  of 
  brownish 
  pink 
  on 
  the 
  gastric 
  

   and 
  branchial 
  regions 
  and 
  posterior 
  margin.

  Two 
  very 
  small 
  females 
  are 
  in 
  the 
  collection 
  from 
  Thursday 
  Island, 
  

   4-6 
  fms. 
  (No. 
  130), 
  first 
  collection, 
  length 
  little 
  over 
  3 
  lines 
  

   (7 
  millim.) 
  ; 
  and 
  a 
  somewhat 
  larger 
  male 
  from 
  the 
  same 
  locality, 
  

   3-4 
  fms. 
  (No. 
  177), 
  second 
  collection. 
  The 
  largest 
  specimen 
  in 
  the 
  

   Museum 
  collection, 
  a 
  male 
  from 
  near 
  Billiton 
  Island, 
  in 
  the 
  Javan 
  

   sea, 
  is 
  about 
  6 
  lines 
  (nearly 
  13 
  millim.) 
  in 
  length. 
  Mr. 
  Haswell 
  

   records 
  this 
  species 
  from 
  Port 
  Denison 
  ; 
  the 
  typical 
  example 
  of 
  

   Adams 
  and 
  White 
  was 
  from 
  Borneo. 
  

  

  Gonatonotus 
  erassimamis 
  of 
  Haswell 
  is 
  a 
  very 
  nearly 
  allied 
  but 
  

   apparently 
  well-characterized 
  species 
  from 
  Port 
  Jackson, 
  differing, 
  

   as 
  its 
  author 
  notes, 
  in 
  its 
  more 
  deeply 
  -cleft 
  rostrum 
  and 
  in 
  other 
  

   points. 
  

  

  32, 
  Euxantlius 
  huonii 
  {Lucas). 
  

  

  A 
  male 
  from 
  Clairmont, 
  east 
  coast 
  of 
  Australia, 
  obtained 
  from 
  a 
  

   coral-reef 
  (No. 
  151), 
  belongs 
  here. 
  

  

  Mr. 
  Haswell 
  mentions 
  (' 
  Catalogue,' 
  p. 
  47) 
  its 
  occurrence 
  at 
  Cape 
  

   Grenville. 
  

  

  M. 
  Alph. 
  Milne-Edwards 
  remarks 
  * 
  that 
  Euxanthiis 
  sculjjtilis, 
  

   Dana, 
  should 
  perhaps 
  not 
  be 
  distinguished 
  from 
  Eu. 
  huonii. 
  If 
  the 
  

   two 
  species 
  are 
  to 
  be 
  united, 
  Dana's 
  specific 
  name 
  will, 
  I 
  believe, 
  

   have 
  priority 
  ; 
  but 
  I 
  prefer 
  to 
  regard 
  them 
  for 
  the 
  present 
  as 
  dis- 
  

   tinct. 
  In 
  Eu. 
  Jiuonii, 
  as 
  described 
  and 
  figured 
  by 
  A. 
  Milne-Edwards, 
  

   and 
  in 
  the 
  specimen 
  of 
  the 
  'Alert' 
  collection, 
  the 
  black 
  coloration 
  

   of 
  the 
  fingers 
  extends 
  along 
  the 
  outer 
  surface 
  of 
  the 
  palm 
  ; 
  no 
  trace 
  

   of 
  this 
  is 
  apparent 
  in 
  Dana's 
  figure 
  of 
  his 
  Eu. 
  scidjptUis, 
  nor 
  in 
  two 
  

   specimens 
  in 
  the 
  British-Museum 
  collection, 
  one 
  of 
  which 
  is 
  from 
  

   the 
  Philippine 
  Islands 
  and 
  designated, 
  I 
  think, 
  by 
  M. 
  A. 
  Milne- 
  

   Edwards 
  Eu. 
  huonii, 
  the 
  other 
  from 
  Trinity 
  Bay, 
  N.E. 
  Australia 
  ; 
  

   both 
  I 
  refer, 
  at 
  least 
  provisionally, 
  to 
  Eu. 
  sculptilis.
