  The 
  question 
  now 
  arises, 
  what 
  is 
  Apholiclernys 
  of 
  Pomel*? 
  

   We 
  are 
  still 
  restricted 
  to 
  the 
  very 
  short 
  original 
  description 
  

   of 
  1847, 
  nothing 
  new 
  having 
  been 
  published 
  since 
  this 
  time. 
  

   Pomel's 
  words 
  are 
  : 
  — 
  a 
  Mr. 
  Leveque 
  arecueilli 
  dans 
  le 
  calcaire 
  

   grossier, 
  a 
  Cuise-la-Motte, 
  pres 
  Compi&gne, 
  des 
  tortues 
  sans 
  

   ^cailles, 
  ou 
  trionyx, 
  qui 
  ont 
  un 
  caractere 
  remarquable 
  dans 
  la 
  

   presence 
  de 
  pieces 
  marginales 
  bien 
  plus 
  developpees 
  que 
  dans 
  

   les 
  cryptopus, 
  avec 
  un 
  plastron, 
  comme 
  dans 
  les 
  gyinnopus. 
  

   C'est 
  un 
  liaison 
  entre 
  les 
  e*mydes 
  et 
  les 
  trionyx, 
  bien 
  plus 
  

   e"vidente 
  que 
  par 
  le 
  tretosternum, 
  puisque 
  certaines 
  emydes 
  

   vivantes 
  ont 
  aussi 
  ces 
  granulations 
  de 
  la 
  surface. 
  Ici 
  c'est 
  un 
  

   carapace 
  a 
  laquelle 
  il 
  ne 
  manque 
  plus 
  que 
  des 
  ecailles 
  pour 
  

   etre 
  celle 
  d'une 
  e*myde 
  a 
  surface 
  tuberculee 
  ; 
  je 
  donne 
  a 
  ce 
  

   nouveau 
  sous-genre 
  le 
  nom 
  d'Apholiclemys, 
  renfermant 
  pro- 
  

   bablement 
  deux 
  especes 
  (A. 
  sublcevis 
  et 
  A. 
  granosa)." 
  

  

  Gervais 
  j" 
  calls 
  these 
  forms 
  " 
  Trionyx 
  granosa 
  " 
  and 
  " 
  Trio- 
  

   nyx 
  laevigata,' 
  1 
  without 
  giving 
  any 
  reasons, 
  and 
  says 
  that 
  

   according 
  to 
  Mr. 
  Graves 
  they 
  are 
  found 
  in 
  " 
  les 
  sables 
  glau- 
  

   conieux 
  moyens 
  de 
  Cuise-la-Motte 
  et 
  de 
  Pierrefonds." 
  The 
  

   " 
  whereabouis 
  " 
  of 
  the 
  type 
  specimens 
  seem 
  to 
  be 
  unknown. 
  

   1 
  am 
  obliged 
  to 
  Prof. 
  A. 
  Gaudry 
  for 
  the 
  following 
  communi- 
  

   cation 
  (April 
  23, 
  1888) 
  : 
  — 
  " 
  On 
  m'a 
  dit 
  que 
  les 
  ^chantillons 
  de 
  

   la 
  collection 
  Leveque 
  sur 
  lesquels 
  M. 
  Pomel 
  dit 
  avoir 
  fait 
  

   son 
  travail 
  ont 
  ete 
  disperses." 
  

  

  It 
  is 
  possible 
  that 
  Apholicltmys 
  may 
  be 
  identical 
  with 
  

   Anosteira 
  or 
  Pseudotrionyx 
  , 
  and 
  it 
  would 
  be 
  very 
  interesting 
  

   if 
  the 
  remains 
  of 
  this 
  form 
  could 
  be 
  figured 
  and 
  redescribed. 
  

   That 
  Pseudotrionyx 
  is 
  a 
  different 
  genus 
  from 
  Anosteira 
  seems 
  

   to 
  be 
  certain. 
  In 
  Pseudotrionyx 
  a 
  small 
  " 
  fontauelle 
  " 
  is 
  

   present 
  between 
  the 
  carapace 
  and 
  plastron 
  (" 
  echancrure 
  natu- 
  

   relle, 
  reste 
  d'une 
  fontauelle 
  laterale," 
  Dollo). 
  Is 
  it 
  not 
  possible 
  

   that 
  this 
  place 
  is 
  filled 
  up 
  by 
  a 
  mesoplastron 
  ? 
  

  

  TheCinosternidse 
  and 
  btaurotypidseare 
  found 
  at 
  present 
  only 
  

   in 
  the 
  northern 
  parts 
  ot 
  South 
  America, 
  in 
  Central 
  America, 
  

   and 
  Is

  oi

  the 
  discovery 
  of 
  such 
  or 
  allied 
  forms 
  in 
  

   the 
  Eocene 
  of 
  Europe 
  is 
  of 
  great 
  interest
