  The 
  Cephalopoda 
  are 
  rare 
  in 
  all 
  the 
  beds 
  of 
  the 
  Lower 
  Oolites 
  of 
  

   Yorkshire, 
  between 
  the 
  Upper 
  Lias 
  and 
  the 
  Kellaways 
  Rock 
  ; 
  in 
  the 
  

   Oxfordian 
  stage 
  the 
  species 
  are 
  greatly 
  augmented. 
  The 
  Belemnite 
  

   in 
  the 
  Grey 
  Limestone 
  is 
  the 
  large 
  and 
  well-known 
  form 
  B. 
  giganteus; 
  

   and 
  the 
  Ammonites 
  are 
  A. 
  Humphresianus, 
  A. 
  Blagdeni, 
  and 
  A. 
  

   Brailcenridgii. 
  It 
  is 
  very 
  doubtful 
  if 
  Am. 
  Parkinsoni 
  has 
  ever 
  been 
  

   found 
  in 
  Yorkshire, 
  although 
  it 
  is 
  said 
  to 
  have 
  occurred.
