  A 
  collection 
  of 
  Labyrinthodont 
  remains 
  from 
  the 
  Keuper 
  Sandstone 
  

   of 
  Warwick 
  has 
  been 
  intrusted 
  to 
  me 
  for 
  description 
  by 
  the 
  Council 
  

   of 
  the 
  "Warwickshire 
  Natural 
  History 
  and 
  Archaeological 
  Society. 
  It 
  

   includes 
  all 
  the 
  material 
  acquired 
  by 
  the 
  "Warwick 
  Museum 
  since 
  

   1842, 
  the 
  date 
  of 
  publication 
  of 
  Professor 
  Owen's 
  well-known 
  

   memoir 
  " 
  On 
  Species 
  of 
  Labyrinthodon 
  from 
  Warwickshire 
  " 
  *, 
  

   which 
  contained 
  figures 
  of 
  all 
  the 
  fossils 
  accumulated 
  up 
  to 
  that 
  

   time. 
  I 
  now 
  propose 
  to 
  describe 
  the 
  additional 
  collection, 
  and 
  after- 
  

   wards 
  to 
  review 
  Prof. 
  Owen's 
  determinations. 
  It 
  may 
  thus 
  be 
  

   possible 
  to 
  combine 
  in 
  one 
  paper 
  all 
  the 
  information 
  on 
  the 
  subject 
  

   at 
  present 
  accessible. 
  The 
  Warwick 
  Museum 
  is 
  fortunate 
  enough 
  

   to 
  possess 
  nearly 
  all 
  the 
  fragments 
  of 
  Triassic 
  Labyrinthodonts 
  

   hitherto 
  found 
  in 
  this 
  country. 
  

  

  Nothing 
  contained 
  in 
  this 
  paper 
  will, 
  I 
  hope, 
  imply 
  unconscious- 
  

   ness 
  on 
  the 
  part 
  of 
  the 
  writer 
  of 
  the 
  vast 
  superiority 
  of 
  the 
  distin- 
  

   guished 
  anatomist 
  and 
  paleontologist, 
  one 
  of 
  whose 
  minor 
  works 
  

   covers 
  part 
  of 
  the 
  ground 
  now 
  to 
  be 
  traversed. 
  The 
  interval 
  between 
  

   1842 
  and 
  1874 
  is 
  the 
  period 
  within 
  which 
  all 
  that 
  is 
  most 
  important 
  

   for 
  the 
  elucidation 
  of 
  the 
  structure 
  of 
  the 
  Labyrinthodonts 
  has 
  been 
  

   accomplished. 
  The 
  writings 
  of 
  Yon 
  Meyer, 
  Plieninger, 
  Quenstedt, 
  

   Burmeister, 
  Huxley, 
  and 
  Hancock, 
  all 
  subsequent 
  to 
  1842, 
  now 
  

   constitute 
  the 
  chief 
  body 
  of 
  the 
  literature 
  of 
  the 
  subject. 
  In 
  endea- 
  

   vouring 
  to 
  interpret 
  the 
  fragmentary 
  remains 
  of 
  the 
  Warwickshire 
  

   Labyrinthodonts 
  we 
  shall 
  necessarily 
  rely 
  upon 
  decisions 
  arrived 
  at 
  

   by 
  naturalists 
  whose 
  material 
  for 
  comparison 
  was 
  so 
  much 
  more 
  

   extensive 
  and 
  perfect 
  than 
  that 
  at 
  Prof. 
  Owen's 
  command. 
  Reasons 
  

   will 
  be 
  given 
  in 
  the 
  following 
  pages 
  for 
  unsettling 
  some 
  of 
  that 
  

   author's 
  determinations. 
  In 
  particular, 
  an 
  impartial 
  reconsideration 
  

   of 
  the 
  five 
  species 
  founded 
  by 
  Prof. 
  Owen 
  seems 
  necessary 
  for 
  the 
  

   true 
  correlation 
  of 
  the 
  Triassic 
  Labyrinthodonts 
  of 
  England 
  and 
  Ger- 
  

   many. 
  The 
  progress 
  of 
  every 
  branch 
  of 
  knowledge 
  calls 
  for 
  such 
  

   revision 
  of 
  long-respected 
  conclusions 
  with 
  unwelcome 
  frequency. 
  

  

  The 
  Warwick 
  specimens, 
  whether 
  owing 
  to 
  the 
  hardness 
  of 
  the 
  

   matrix, 
  or 
  to 
  the 
  conditions 
  of 
  fossilization, 
  are 
  singularly 
  frag- 
  

   mentary. 
  In 
  this 
  respect 
  they 
  present 
  difficulties 
  from 
  which 
  the 
  

   fortunate 
  describers 
  of 
  the 
  nearly 
  entire 
  crania 
  found 
  in 
  the 
  shales 
  

   and 
  sandstones 
  of 
  Wurttemberg 
  were 
  exempt. 
  Though 
  fragmentary, 
  

   the 
  fossils 
  now 
  under 
  consideration 
  are 
  free 
  from 
  distortion, 
  and 
  

   often 
  show 
  details 
  of 
  structure 
  with 
  beautiful 
  clearness. 
  No 
  pains
