  specimens 
  (one

   with 
  relatively

  The

  specimens 
  of 
  Leptolepis 
  from 
  the 
  Upper 
  Lias 
  of 
  

  

  Dumbleton, 
  Gloucestershire, 
  represent 
  the 
  form 
  named 
  L. 
  concen- 
  

  

  tricus 
  by 
  Egerton 
  (Quart. 
  Journ.

  This 
  

  

  is 
  said 
  to 
  be 
  distinguished 
  from 
  the 
  so-called 
  L. 
  constrictus 
  (identified 
  

  

  above 
  with 
  L. 
  bronni) 
  by 
  its 
  relatively 
  larger 
  head, 
  thicker 
  scales, 
  

  

  and 
  smooth 
  preoperculum 
  ; 
  but, 
  judging 
  from 
  present 
  evidence, 
  it 
  

  

  seems 
  likely 
  that 
  all 
  these 
  differences 
  will 
  prove 
  to 
  be 
  merely 
  due 
  

  

  to 
  differences 
  in 
  the 
  state 
  of 
  preservation.

  the 
  corresponding
