  the

  — 
  "Nous 
  avons 
  

   distrait 
  du 
  groupe 
  des 
  Oxystomes 
  la 
  famille 
  des 
  Raninides 
  qui 
  nous 
  parait 
  

   aberrante 
  a 
  plus 
  d'un 
  titre. 
  Ces 
  Oxystomes 
  anormaux 
  sont 
  representes 
  par 
  

   de 
  curieuses 
  formes 
  nouvelles 
  dans 
  les 
  mate'riaux 
  recueillis 
  par 
  le 
  Blake 
  ; 
  

   nous 
  les 
  etudions 
  avec 
  la 
  plus 
  grand 
  detail, 
  et 
  ils 
  font 
  prochainement 
  l'objet 
  

   d'une 
  etude 
  tres 
  complete." 
  So 
  far 
  as 
  I 
  have 
  been 
  able 
  to 
  ascertain 
  by 
  

   search 
  in 
  the 
  records 
  of 
  zoological 
  literature, 
  somewhat 
  incomplete 
  as 
  they 
  

   are 
  through 
  disturbances 
  arising 
  out 
  of 
  the 
  late 
  war, 
  this 
  promised 
  memoir 
  

   on 
  the 
  Raninidse 
  has 
  not 
  yet 
  been 
  published, 
  and 
  the 
  following 
  pages 
  give 
  

   an 
  account 
  of 
  my 
  own 
  studies 
  on 
  this 
  aberrant 
  and, 
  as 
  I 
  shall 
  strive 
  to 
  show, 
  

   primitive 
  family 
  of 
  crabs. 
  My 
  attention 
  was 
  directed 
  to 
  them 
  some 
  eight 
  

   years 
  ago, 
  and 
  I 
  spent 
  some 
  time 
  in 
  the 
  attempt 
  to 
  procure 
  a 
  well-preserved 
  

   specimen 
  of 
  Ranina, 
  of 
  which 
  I 
  had 
  several 
  ill-preserved 
  examples 
  collected 
  

   by 
  Messrs. 
  C. 
  & 
  E. 
  Hose 
  in 
  Celebes. 
  Eventually, 
  after 
  much 
  fruitless 
  corre- 
  

   spondence 
  with 
  other 
  naturalists, 
  I 
  obtained 
  a 
  fine 
  specimen 
  of 
  Ranina 
  

   dentata 
  from 
  Professor 
  Kishinoye, 
  of 
  Tokio. 
  It 
  was 
  admirably 
  preserved 
  in 
  

   spirit, 
  and 
  I 
  have 
  to 
  express 
  my 
  best 
  thanks 
  to 
  him 
  for 
  his 
  trouble 
  in 
  pro- 
  

   curing 
  me 
  so 
  excellent 
  an 
  example 
  for 
  study 
  and 
  dissection. 
  

  

  In 
  addition 
  to 
  Ranina, 
  I 
  had 
  examples 
  of 
  the 
  following 
  members 
  of 
  the 
  

   family 
  in 
  the 
  collections 
  of 
  the 
  Oxford 
  University 
  Museum 
  : 
  — 
  

  

  Notopus 
  dorsipes, 
  Fabr. 
  ; 
  two 
  examples 
  collected 
  by 
  H.M.S. 
  'Nassau' 
  in 
  

  

  the 
  Sulu 
  Sea, 
  1871-72. 
  

   Raninoides 
  personatus, 
  White 
  MS., 
  Henderson 
  ; 
  one 
  example 
  from 
  the 
  

  

  Bay 
  of 
  Bengal, 
  presented 
  to 
  the 
  University 
  by 
  the 
  Calcutta 
  Museum. 
  

   Lyreidus 
  tridentatus, 
  de 
  Haan 
  ; 
  two 
  examples 
  from 
  Port 
  Jackson, 
  presented 
  

  

  to 
  the 
  University 
  by 
  the 
  Trustees 
  of 
  the 
  British 
  Museum 
  of 
  Natural 
  

  

  History. 
  

   Two 
  examples 
  of 
  a 
  species 
  labelled 
  " 
  Notopus," 
  collected 
  in 
  the 
  Sulu 
  Sea 
  

  

  by 
  H.M.S. 
  ' 
  Nassau.' 
  These 
  I 
  am 
  describing 
  as 
  a 
  new 
  genus 
  and 
  

  

  species 
  under 
  the 
  name 
  of 
  Notosceles 
  chimmonis.
