  upper 
  face 
  of 
  the 
  palms 
  in 
  oue 
  (the 
  largest) 
  of 
  the 
  Shark-Bay 
  

   specimens. 
  

  

  As 
  there 
  are 
  in 
  the 
  British-Museum 
  collection 
  adult 
  examples 
  

   undoubtedly 
  referable 
  to 
  L. 
  nodosus 
  from 
  Shark 
  Bay, 
  collected 
  by 
  

   Lieut. 
  Suckling, 
  K.N., 
  and 
  presented 
  by 
  W. 
  Wykeham 
  Perry, 
  Esq., 
  

   it 
  is 
  possible 
  that 
  L. 
  intermedius 
  may 
  represent 
  merely 
  a 
  young 
  

   condition 
  of 
  this 
  species. 
  

  

  26. 
  Lamhrus 
  turriger, 
  White. 
  

  

  An 
  adult 
  male 
  and 
  female, 
  in 
  somewhat 
  imperfect 
  condition, 
  are 
  

   in 
  the 
  second 
  collection, 
  from 
  the 
  Arafura 
  Sea, 
  32-36 
  fms. 
  (No. 
  160). 
  

  

  These 
  specimens 
  are 
  certainly 
  identical 
  with 
  specimens 
  from 
  the 
  

   Philipijino 
  Islands 
  {Cumimj) 
  and 
  Borneo 
  (Admiralty), 
  designated 
  

   L. 
  turriger 
  by 
  White, 
  although 
  in 
  the 
  adult 
  male 
  received 
  from 
  

   Dr. 
  Coppinger 
  the 
  spines 
  of 
  the 
  carapace 
  are 
  considerably 
  longer 
  

   than 
  in 
  the 
  largest 
  of 
  these 
  examples. 
  

  

  Mr. 
  Haswell 
  mentions 
  the 
  occurrence 
  of 
  L. 
  turriger 
  at 
  Darnley 
  Island. 
  

  

  As 
  the 
  description 
  and 
  figure 
  of 
  Adams 
  and 
  "White* 
  give 
  an 
  

   inadequate 
  idea 
  of 
  this 
  very 
  remarkable 
  form, 
  I 
  subjoin 
  the 
  following 
  

   description 
  of 
  the 
  principal 
  specific 
  characters, 
  based 
  upon 
  an 
  ex- 
  

   amination 
  of 
  Dr. 
  Cojjpinger's 
  adult 
  male 
  : 
  — 
  

  

  The 
  cara{)ace 
  is 
  somewhat 
  rhomboidal, 
  constricted 
  behind 
  the 
  

   orbits 
  ; 
  the 
  front 
  promiuent, 
  triangulate, 
  acute 
  and 
  deflexed, 
  with 
  a 
  

   small 
  tooth 
  or 
  tubercle 
  on 
  each 
  side 
  near 
  the 
  base. 
  The 
  carapace 
  

   is 
  armed 
  with 
  long 
  spines, 
  whereof 
  one 
  is 
  situate 
  on 
  the 
  gastric, 
  one 
  

   (very 
  long) 
  on 
  the 
  cardiac, 
  and 
  one 
  (very 
  long) 
  on 
  each 
  branchial 
  

   region 
  ; 
  these 
  spines 
  are 
  vertical 
  ; 
  there 
  is 
  besides 
  a 
  shorter 
  spine 
  

   behind 
  and 
  in 
  front 
  of 
  each 
  of 
  the 
  branchial 
  spines, 
  and 
  two, 
  directed 
  

   oblicjuely 
  backwards, 
  on 
  the 
  posterior 
  margin 
  of 
  the 
  carapace. 
  The 
  

   chclipedes 
  are 
  very 
  long, 
  more 
  than 
  4k 
  times 
  as 
  long 
  as 
  the 
  carapace, 
  

   blender, 
  and 
  approaching 
  more 
  nearly 
  to 
  a 
  cylindrical 
  form 
  than 
  in 
  any 
  

   other 
  species 
  I 
  have 
  examined 
  ; 
  the 
  palm 
  is 
  scarcely 
  more 
  dilated 
  

   than 
  the 
  wrist; 
  and 
  both 
  arm, 
  wrist, 
  and 
  palm 
  are 
  closely 
  tuberculated 
  

   both 
  on 
  their 
  upper 
  and 
  under 
  surfaces 
  ; 
  the 
  anterior 
  and 
  jDosterior 
  

   margins 
  are 
  armed 
  with 
  longer 
  tubercles 
  or 
  short 
  spines, 
  nearly 
  as 
  

   in 
  the 
  figure 
  of 
  Adams 
  and 
  White. 
  In 
  the 
  smaller 
  examples 
  some 
  

   of 
  the 
  shorter 
  spines 
  of 
  the 
  carapace 
  may 
  not 
  be 
  always 
  developed, 
  

   but 
  the 
  four 
  long 
  vertical 
  spines 
  of 
  the 
  gastric, 
  cardiac, 
  and 
  branchial 
  

   regions 
  and 
  the 
  two 
  spines 
  of 
  the 
  posterior 
  margin 
  are 
  always 
  

   distinct. 
  

  

  27. 
  Lambrus 
  hoplonotus, 
  var. 
  granulosus, 
  Miers. 
  

  

  Three 
  specimens 
  from 
  Flinders, 
  Clairmont, 
  N.E. 
  Australia, 
  11 
  fms. 
  

   (No. 
  108, 
  first 
  collection), 
  and 
  one 
  from 
  Port 
  Darwin, 
  12 
  fms. 
  

   (second 
  collection), 
  agree 
  more 
  nearly 
  with 
  this 
  variety 
  than 
  with 
  any 
  

   other 
  of 
  this 
  protean 
  species, 
  but 
  exhibit 
  a 
  marked 
  approach 
  to 
  var. 
  

   longiocidis 
  in 
  the 
  subspiniform 
  tubercles 
  of 
  the 
  gastric, 
  cardiac, 
  and
