  appearance 
  in 
  the 
  Cephalopoda- 
  bed, 
  although 
  the 
  same 
  Ammonite- 
  

   croups 
  remained. 
  The 
  Author 
  surmised 
  that 
  the 
  Striatulus- 
  

   beds 
  disappeared 
  towards 
  Burton 
  Bradstock, 
  indicating 
  a 
  palseonto- 
  

   logical 
  break. 
  In 
  Yorkshire, 
  the 
  Striatulus-heds 
  were 
  in 
  Liassic 
  

   shales. 
  No 
  doubt 
  the 
  family 
  Hildoceratidae 
  constituted 
  a 
  bond 
  of 
  

   union 
  between 
  Lias 
  and 
  Oolite 
  ; 
  but 
  if 
  this 
  principle 
  were 
  generally 
  

   adopted, 
  this 
  would 
  help 
  to 
  divide 
  the 
  Lias 
  also. 
  Hence 
  his 
  ob- 
  

   jection 
  to 
  the 
  proposed 
  "Toarciau." 
  

  

  Ilev. 
  H. 
  H. 
  Win 
  wood 
  declared 
  that 
  lithology 
  was 
  cast 
  to 
  the 
  

   winds 
  if 
  we 
  accepted 
  the 
  conclusions 
  of 
  Mr. 
  Bucknian's 
  paper. 
  How- 
  

   ever, 
  he 
  was 
  glad 
  that 
  the 
  Author 
  had 
  done 
  away 
  with 
  the 
  

   misleading 
  name 
  " 
  Cephalopoda-bed." 
  In 
  addition 
  to 
  Amm. 
  striatulus, 
  

   found 
  in 
  the 
  Midford 
  Sands 
  in 
  a 
  cutting 
  uear 
  Bath, 
  he 
  had 
  found 
  

   portions 
  of 
  another 
  Ammonite, 
  apparently 
  too 
  imperfect 
  for 
  Mr. 
  Buck- 
  

   man 
  to 
  define, 
  and 
  also 
  portions 
  of 
  a 
  Brachiopod 
  defined 
  by 
  Chas. 
  

   Moore 
  as 
  JRhynchonella 
  spinosa. 
  He 
  did 
  not 
  fully 
  recognize 
  Mr. 
  

   Buckman's 
  section 
  at 
  Lyncombe. 
  

  

  Mr. 
  Hudleston 
  was 
  glad 
  to 
  hear 
  a 
  confirmation 
  of 
  the 
  first 
  part 
  

   of 
  Mr. 
  Buckman's 
  contention 
  from 
  so 
  good 
  a 
  palaeontologist 
  as 
  Prof. 
  

   Blake. 
  Lately, 
  whilst 
  examining 
  the 
  Inferior 
  Oolite 
  of 
  the 
  south- 
  

   west 
  for 
  a 
  particular 
  purpose, 
  he 
  had 
  come 
  to 
  the 
  conclusion 
  that 
  

   the 
  Yeovil 
  Sands 
  were 
  on 
  a 
  different 
  horizon 
  from 
  those 
  of 
  the 
  

   Cotteswolds 
  ; 
  hence 
  he 
  could 
  not 
  think 
  it 
  was 
  advisable 
  to 
  describe 
  

   them 
  by 
  the 
  same 
  name, 
  except 
  on 
  very 
  general 
  grounds. 
  When 
  

   Phillips 
  selected 
  the 
  term 
  " 
  Midford 
  " 
  for 
  the 
  " 
  Sands 
  " 
  generally, 
  it 
  

   was 
  probable 
  that 
  he 
  had 
  not 
  an 
  intimate 
  knowledge 
  of 
  any 
  of 
  them. 
  

   As 
  regards 
  the 
  real 
  Midford 
  Sands 
  the 
  only 
  thing 
  clear 
  about 
  them 
  

   was 
  that 
  they 
  lay 
  above 
  the 
  Striatulus-be&s, 
  and 
  were 
  consequently 
  

   more 
  allied 
  to 
  the 
  Yeovil 
  than 
  to 
  the 
  Cotteswold 
  Sands. 
  If 
  Bhyn- 
  

   chonella 
  spinosa 
  had 
  really 
  been 
  found 
  the 
  Midford 
  Sands 
  would 
  belong 
  

   to 
  the 
  uppermost 
  zone 
  of 
  the 
  Inferior 
  Oolite. 
  It 
  was 
  suggested 
  that 
  

   this 
  might 
  have 
  been 
  Bliynch. 
  cynocephala 
  . 
  In 
  the 
  section 
  near 
  Mid- 
  

   ford 
  the 
  beds 
  of 
  the 
  Pa 
  rkinsoni-zone 
  rested 
  directly 
  on 
  the 
  Sands, 
  show- 
  

   ing 
  the 
  absence 
  of 
  the 
  Murcliisonce- 
  and 
  Bwnphriesianum-zones 
  ; 
  

   hence 
  there 
  could 
  be 
  no 
  question 
  of 
  passage 
  where 
  such 
  a 
  break 
  

   existed. 
  

  

  Mr. 
  Buckman's 
  proposal 
  to 
  establish 
  the 
  " 
  Toarcian 
  " 
  at 
  the 
  expense 
  

   of 
  the 
  Upper 
  Lias 
  and 
  the 
  Lower 
  Division 
  of 
  the 
  Inferior 
  Oolite 
  was 
  

   scarcely 
  practicable, 
  though 
  we 
  were 
  indebted 
  to 
  the 
  Author 
  for 
  

   specifying 
  the 
  particular 
  genera 
  of 
  the 
  Hildoceratidae 
  which 
  charac- 
  

   terized 
  the 
  several 
  series. 
  In 
  Dorsetshire 
  the 
  palaeontological 
  hiatus 
  

   between 
  the 
  Lower 
  and 
  Upper 
  Divisions 
  of 
  the 
  Inferior 
  Oolite 
  was 
  

   undoubtedly 
  very 
  great, 
  and 
  by 
  no 
  means 
  confined 
  to 
  the 
  Cephalopoda. 
  

   But 
  this 
  could 
  not 
  outweigh 
  the 
  many 
  considerations 
  on 
  the 
  other 
  

   side. 
  If 
  Mr. 
  Buckman's 
  views 
  on 
  this 
  point 
  were 
  accepted 
  the 
  Infe- 
  

   rior 
  Oolite 
  would 
  disappear, 
  the 
  Upper 
  Division 
  being 
  thrown 
  to 
  the 
  

   Bathonian 
  .
