  COLLECTIONS 
  FROM 
  MELANESIA. 
  

  

  I 
  designate 
  this 
  common 
  species 
  (which 
  is 
  ■usually 
  referred 
  to 
  

   under 
  the 
  Fabrician 
  name 
  quadridens 
  or 
  quadrldentata) 
  D. 
  dorsipes, 
  

   because 
  Linna3us's 
  somewhat 
  detailed 
  description 
  in 
  the 
  ' 
  Museum 
  

   Ludovicse 
  Ulricse 
  ' 
  agrees 
  with 
  it 
  excellently 
  in 
  almost 
  every 
  par- 
  

   ticular, 
  and 
  more 
  especially 
  as 
  regards 
  the 
  disposition 
  of 
  the 
  spines 
  

   on 
  the 
  postabdominal 
  segments 
  of 
  the 
  male, 
  where, 
  however, 
  it 
  

   must 
  be 
  noted 
  that 
  there 
  is 
  usually 
  a 
  tubercle 
  on 
  the 
  first 
  postabdo- 
  

   minal 
  segment, 
  which 
  is 
  described 
  by 
  Linnaeus 
  as 
  " 
  itiermis.'' 
  In 
  the 
  

   female 
  there 
  are 
  between 
  the 
  larger 
  spines 
  or 
  tubercles 
  of 
  the 
  post- 
  

   abdominal 
  segments 
  several 
  smaller 
  spinules. 
  If 
  this 
  species 
  be 
  not 
  

   truly 
  I), 
  dorsipes 
  of 
  Linnaeus, 
  it 
  would 
  appear 
  (as 
  Hilgendorf 
  notes) 
  

   that 
  Herbst's 
  name 
  of 
  D. 
  frascone 
  has 
  stiU 
  priority 
  over 
  the 
  Pabrician 
  

   designation. 
  

  

  Of 
  this 
  species 
  there 
  are 
  specimens 
  in 
  the 
  British-Museum 
  collec- 
  

   tion 
  from 
  several 
  localities 
  on 
  the 
  North-eastern 
  coast 
  of 
  Australia, 
  

   e. 
  g., 
  Torres 
  Straits 
  (J. 
  B. 
  Jidces), 
  Dunk 
  Island 
  (J. 
  Macgillivray, 
  

   H.M.S. 
  ' 
  Rattlesnake 
  '), 
  and 
  near 
  Cumberland 
  Island 
  (J. 
  Macgilli- 
  

   vray) 
  ; 
  also 
  a 
  small 
  specimen 
  from 
  Shark 
  Bay, 
  W. 
  Australia 
  (F. 
  

   M. 
  Rayner, 
  H.M.S. 
  ' 
  Herald 
  '), 
  in 
  which 
  the 
  eye-peduncles 
  are 
  rela- 
  

   tively 
  much 
  longer, 
  probably 
  belongs 
  here. 
  There 
  are, 
  besides, 
  

   specimens 
  in 
  the 
  Museum 
  collection 
  from 
  the 
  Indian 
  Ocean 
  (Bard- 
  

   wicl-e) 
  ; 
  Ceylon 
  {E. 
  W. 
  H. 
  JBoldsivorth) 
  ; 
  Philippine 
  Islands 
  ( 
  Cuming) 
  ; 
  

   Jaj^an 
  {Leyden 
  collection); 
  and 
  China 
  seas 
  {E. 
  Swinhoe). 
  

  

  There 
  are 
  in 
  the 
  Museum 
  collection 
  two 
  specimens 
  from 
  Shanghai, 
  

   which 
  have 
  the 
  carapace 
  and 
  ambulatory 
  legs 
  much 
  more 
  tomentose, 
  

   the 
  median 
  spines 
  of 
  the 
  front 
  less 
  prominent, 
  and 
  the 
  right-hand 
  

   chela 
  (in 
  the 
  male) 
  considerably 
  developed, 
  with 
  the 
  palm 
  swollen 
  

   and 
  vertically 
  very 
  deep 
  ; 
  they 
  are 
  probably 
  only 
  old 
  and 
  large 
  speci- 
  

   mens 
  of 
  this 
  species. 
  

  

  Three 
  female 
  specimens 
  from 
  China 
  only 
  differ 
  in 
  the 
  remarkable 
  

   breadth 
  of 
  the 
  carapace 
  at 
  the 
  branchial 
  regions, 
  and 
  the 
  larger 
  size 
  

   of 
  some 
  of 
  the 
  wart-like 
  tubercles 
  of 
  the 
  dorsal 
  surface, 
  and 
  are 
  

   probably 
  not 
  distinct. 
  A 
  specimen 
  from 
  Canton 
  Province 
  (Dr. 
  Can- 
  

   tor) 
  approaches 
  in 
  the 
  lesser 
  width 
  of 
  the 
  carapace 
  ordinary 
  females 
  

   of 
  D. 
  dorsipes. 
  In 
  all 
  of 
  these 
  the 
  postabdomen 
  is 
  deficient. 
  

  

  Finally, 
  two 
  specimens 
  from 
  Zebu, 
  Philippines 
  (Cuming), 
  which 
  

   White 
  has 
  referred 
  to 
  D. 
  callida, 
  Fabr., 
  only 
  differ 
  in 
  the 
  slender 
  

   legs 
  and 
  in 
  the 
  obsolescence 
  of 
  the 
  tubercles 
  of 
  the 
  carapace, 
  whose 
  

   surface, 
  however, 
  is 
  uneven 
  and 
  elevated 
  where 
  these 
  tubercles 
  

   ordinarily 
  exist. 
  They 
  may 
  be 
  distinct 
  or 
  only 
  a 
  variety 
  of 
  D. 
  

   dorsipes. 
  

  

  115. 
  Dorippe 
  australiensis. 
  (Plate 
  XXVI. 
  fig. 
  D.) 
  

  

  I 
  thus 
  designate 
  a 
  small 
  example 
  obtained 
  at 
  Port 
  Denison, 
  4 
  fms. 
  ; 
  

   also 
  two 
  specimens 
  from 
  Moreton 
  Bay 
  (purcliased), 
  and 
  four 
  from 
  

   the 
  Australian 
  coast 
  (Dr. 
  Bowerbank) 
  , 
  but 
  without 
  any 
  special 
  in- 
  

   dication 
  of 
  locality, 
  in 
  the 
  British-Museum 
  collection. 
  

  

  This 
  form 
  is 
  evidently 
  very 
  nearly 
  allied 
  to 
  D. 
  grcmidata, 
  De
