  Wealden 
  remains 
  in 
  the 
  British 
  Museum 
  as 
  referable 
  to 
  the 
  

   American 
  genus 
  Morosaurus, 
  and 
  that 
  he 
  also 
  considered 
  Omosaurus 
  

   (preoccupied) 
  inseparable 
  from 
  Stegosaurus 
  — 
  with 
  both 
  of 
  which 
  

   conclusions 
  the 
  Author 
  concurred. 
  In 
  referring 
  the 
  femur 
  described 
  

   above 
  to 
  Camptosaurus, 
  the 
  Author 
  stated 
  that, 
  as 
  he 
  could 
  find 
  

   no 
  points 
  of 
  distinction, 
  he 
  followed 
  his 
  usual 
  rule 
  of 
  regarding 
  

   forms 
  as 
  generically 
  identical 
  until 
  they 
  could 
  be 
  proved 
  to 
  be 
  

   different, 
  in 
  preference 
  to 
  the 
  opposite 
  course. 
  

  

  With 
  regard 
  to 
  the 
  statement 
  that 
  Thaumatosaurus 
  should 
  be 
  

   included 
  in 
  Pliosaurus, 
  the 
  Author 
  mentioned 
  that 
  the 
  former 
  was 
  

   from 
  the 
  Great 
  Oolite 
  ; 
  and 
  observed 
  that 
  if 
  that 
  view 
  was 
  main- 
  

   tained 
  it 
  would 
  be 
  necessary 
  to 
  include 
  in 
  the 
  same 
  genus 
  the 
  

   species 
  (Plesiosaurus 
  Cramptoni) 
  on 
  which 
  ffliowialeosaurus 
  was 
  

   founded, 
  as 
  well 
  as 
  other 
  allied 
  types 
  with 
  a 
  short 
  mandibular 
  

   symphysis 
  and 
  a 
  peculiar 
  type 
  of 
  pectoral 
  girdle, 
  and 
  also 
  the 
  form 
  

   described 
  above 
  as 
  Peloneustes, 
  all 
  these 
  forms 
  having 
  more 
  or 
  

   less 
  triangulated 
  teeth. 
  The 
  points 
  on 
  which 
  the 
  Author 
  differed 
  

   from 
  Prof. 
  Seeley 
  in 
  regard 
  to 
  the 
  so-called 
  Elasmosaurians 
  were 
  

   merely 
  ones 
  of 
  degree, 
  the 
  Author 
  preferring 
  to 
  use 
  a 
  generic 
  term 
  

   in 
  the 
  sense 
  in 
  which 
  Professors 
  Cope 
  and 
  Seeley 
  employ 
  a 
  family 
  

   one.
