  the 
  fact 
  that 
  I 
  retain 
  llegerle's 
  name 
  siibgenerically 
  ; 
  T. 
  litteratus, 
  

   [Megeiie's 
  monotype, 
  being 
  at 
  most 
  subgenerically 
  different 
  from 
  

   Papilla 
  {Rxulitafes) 
  decussata, 
  L. 
  As 
  Da 
  Costa's 
  first 
  species 
  and 
  as 
  

   the 
  only 
  one 
  of 
  his 
  species 
  to 
  be 
  mentioned 
  under 
  the 
  revived 
  name 
  

   by 
  !Morch, 
  the 
  latter 
  must 
  be 
  taken 
  as 
  the 
  type 
  if 
  Cuneus 
  is 
  to 
  be 
  

   retained. 
  

  

  If, 
  after 
  a 
  selection 
  of 
  a 
  type 
  has 
  been 
  made 
  under 
  the 
  existing 
  

   rules, 
  appeals 
  to 
  the 
  Commission 
  for 
  a 
  new 
  change 
  are 
  to 
  be 
  allowed, 
  

   it 
  is 
  evident 
  that 
  stability 
  of 
  names 
  will 
  never 
  be 
  attained.
