  E. 
  Olivier 
  has 
  recorded 
  the 
  very 
  extraordinary 
  case 
  

   of 
  an 
  adult 
  specimen 
  in 
  which 
  the 
  notochordal 
  larval 
  tail 
  

   had 
  not 
  only 
  been 
  retained, 
  but 
  had 
  continued 
  to 
  grow 
  

   in 
  proportion 
  with 
  the 
  animal. 
  The 
  specimen, 
  which 
  

   measures 
  63 
  mm. 
  from 
  snout 
  to 
  vent, 
  with 
  a 
  tail- 
  

   length 
  of 
  54 
  mm., 
  is 
  figured 
  in 
  the 
  Revue 
  Scientifique 
  

   du 
  Bourbonnais.

  Geographical 
  Variations. 
  — 
  The 
  differences 
  between 
  

   European 
  and 
  Japanese 
  specimens 
  are 
  considerable, 
  

   and 
  have 
  induced 
  some 
  authors, 
  to 
  regard 
  the 
  two 
  

   as 
  distinct 
  species. 
  These 
  differences, 
  which 
  reside 
  

   chiefly 
  in 
  the 
  greater 
  size 
  and 
  perfect 
  distinctness 
  of 
  

   the 
  tympanum, 
  the 
  black 
  lateral 
  stripe, 
  and 
  the 
  deep 
  

   black 
  spots 
  or 
  marblings 
  of 
  the 
  lower 
  parts 
  in 
  the
