   The 
  genus 
  Everettia 
  was 
  established, 
  on 
  anatomical 
  grounds, 
  as 
  a 
  

   subgenus 
  of 
  Byaliia, 
  by 
  Col. 
  God 
  win- 
  Austen 
  in 
  1891 
  ^ 
  with 
  Helix 
  

   jucunda^ 
  Pfr., 
  as 
  the 
  type. 
  He 
  included 
  six 
  other 
  species. 
  One 
  of 
  

   these, 
  however, 
  as 
  pointed 
  out 
  by 
  Smith, 
  i.e. 
  E. 
  hocki, 
  Issel, 
  "is 
  

   purely 
  imaginary 
  and 
  is 
  not 
  described 
  at 
  the 
  reference 
  given." 
  ^ 
  

  

  In 
  1895 
  Smith 
  raised 
  Everetlia 
  to 
  generic 
  rank 
  and 
  added 
  five 
  new 
  

   species.* 
  The 
  next 
  author 
  to 
  deal 
  with 
  the 
  genus 
  from 
  an 
  

   anatomical 
  point 
  of 
  view 
  was 
  Wiegraann,^ 
  who 
  gave 
  details 
  of 
  three 
  

   species^'M6'?m(frt, 
  Pfr., 
  moelleyidorffi., 
  Kob., 
  and 
  fiilrocarnea, 
  Mart.; 
  

   the 
  two 
  last 
  come 
  from 
  the 
  Celebes, 
  whereas 
  all 
  the 
  other 
  species 
  

   hitherto 
  referred 
  to 
  Everettia 
  are 
  from 
  Borneo 
  and 
  adjacent 
  small 
  

   islands 
  to 
  the 
  west. 
  

  

  Finally 
  Kobelt 
  again 
  reduced 
  Everettia 
  to 
  a 
  subgenus 
  of 
  Macro- 
  

   chlamys,^ 
  adding 
  two 
  Philippine 
  species 
  — 
  pseuste.t, 
  Ffr., 
  and 
  sanchezi, 
  

   Quad. 
  & 
  MlldfP. 
  — 
  and 
  one 
  Siamese 
  form, 
  dohrniana, 
  Pfr. 
  It 
  remains 
  

   to 
  be 
  seen 
  whether 
  anatomical 
  investigation 
  will 
  confirm 
  these 
  three 
  

   references. 
  

  

  The 
  new 
  species, 
  now 
  described, 
  is 
  based 
  on 
  two 
  specimens 
  received 
  

   from 
  a 
  natural 
  history 
  dealer 
  as 
  far 
  back 
  as 
  1904.
