  [Plate

  The 
  genus 
  Ornithocheirus 
  was 
  founded 
  by 
  Seeley 
  on 
  numerous 
  

   fragments 
  of 
  jaws 
  and 
  odd 
  bones 
  of 
  Pterodactyls 
  from 
  the 
  

   Cambridge 
  Greensand, 
  pi*eserved 
  in 
  the 
  Woodwardian 
  (now 
  

   the 
  Sedgwick) 
  Museum 
  of 
  the 
  University 
  of 
  Cambridge. 
  All 
  

   the 
  specimens 
  are 
  more 
  or 
  less 
  water-worn. 
  The 
  most 
  perfect 
  

   are 
  a 
  humerus, 
  femur, 
  and 
  several 
  carpal 
  bones. 
  The 
  first 
  

   character 
  laid 
  down 
  as 
  pertaining 
  to 
  the 
  genus 
  * 
  was 
  " 
  no 
  

   teeth 
  anterior 
  to 
  the 
  palate," 
  which, 
  later 
  f, 
  was 
  negatived 
  

   by 
  the 
  statement 
  that 
  " 
  the 
  teeth 
  are 
  prolonged 
  anterior 
  to 
  

   the 
  muzzle/' 
  and 
  another 
  character 
  is 
  added, 
  " 
  the 
  palate 
  

   has 
  a 
  longitudinal 
  ridge.'"' 
  In 
  1881 
  J 
  an 
  explanation 
  of 
  the 
  

   amendment 
  was 
  given^ 
  from 
  which 
  it 
  ajjpears 
  that 
  the 
  genus 
  

   Ornithocheirus 
  was 
  oiiginated 
  to 
  include 
  three 
  deep 
  clul)- 
  

   shaped 
  jaws 
  of 
  the 
  type 
  of 
  Pterodactylus 
  simus, 
  Owen, 
  and 
  

   Ptenodactylus, 
  for 
  the 
  spear-shaped 
  jaws 
  of 
  the 
  tyjie 
  of 
  

   Pterodactylus 
  sedgivicki, 
  Owen.
