  Lias 
  of 
  

   Whitby, 
  exhibiting 
  a 
  regular 
  series 
  of 
  plates, 
  which 
  

   seem 
  to 
  be 
  an 
  operculum 
  and 
  suboperculum 
  followed 
  

   below 
  by 
  seven 
  branchiostegal 
  rays, 
  exposed

   small, 
  only 
  one-third

   culum 
  beneath 
  it.
