  The

  of 
  the 
  Speeton 
  Clay 
  : 
  Zone 
  of 
  Belemnites 
  

   minimus, 
  List. 
  

  

  There 
  is 
  no 
  section 
  at 
  Speeton 
  showing 
  the 
  point 
  of 
  emergence 
  of 
  

   the 
  clays 
  from 
  beneath 
  the 
  Chalk, 
  for 
  as 
  soon 
  as 
  the 
  base 
  of 
  the 
  

   chalk 
  is 
  lifted 
  above 
  the 
  shore-line 
  it 
  hides 
  everything 
  below 
  by 
  

   its 
  continual 
  slipping. 
  

  

  I 
  believe 
  it 
  is 
  usually 
  taken 
  for 
  granted 
  that 
  the 
  remarkable 
  

   unconformity 
  seen 
  below 
  the 
  Red 
  Chalk 
  along 
  the 
  western 
  edge 
  of 
  

   the 
  Wolds 
  extends 
  to 
  Speeton, 
  and 
  marks 
  the 
  junction 
  of 
  the 
  Eed 
  

   Chalk 
  there 
  with 
  the 
  underlying 
  beds. 
  The 
  Rev. 
  T. 
  Wiltshire, 
  

   however, 
  has 
  described 
  the 
  Red 
  Chalk 
  as 
  passing 
  into 
  the 
  Speeton 
  

   Clay 
  § 
  ; 
  and 
  at 
  a 
  later 
  date, 
  C. 
  J. 
  A. 
  Meyer 
  published 
  a 
  brief 
  note 
  

   on 
  a 
  section 
  at 
  Speeton 
  in 
  which 
  this 
  passage 
  was 
  very 
  distinctly 
  

   seen 
  |j, 
  but 
  his 
  note, 
  perhaps 
  from 
  lack 
  of 
  full 
  information 
  concerning 
  

   the 
  position 
  of 
  the 
  section 
  in 
  these 
  slipped 
  cliffs, 
  does 
  not 
  seem 
  to 
  

   have 
  had 
  much 
  effect 
  in 
  altering 
  the 
  prevalent 
  view. 
  There 
  can 
  be 
  

   no 
  doubt, 
  however, 
  that 
  we 
  have 
  at 
  Speeton 
  below 
  the 
  Red 
  Chalk 
  beds 
  

   of 
  marly 
  shale 
  and 
  clay, 
  which, 
  while 
  they 
  present 
  many 
  of 
  the 
  

  

  * 
  Several 
  species 
  will 
  be 
  found 
  recorded 
  in 
  this 
  list 
  which 
  occur 
  in 
  the 
  Lower 
  

   Gault, 
  showing 
  the 
  gradually 
  changing 
  character 
  of 
  the 
  fauna. 
  The 
  list 
  is 
  

   admittedly 
  very 
  incomplete, 
  partly 
  owing 
  to 
  the 
  rarity 
  of 
  good 
  opportunities 
  

   for 
  collecting 
  from 
  these 
  beds, 
  and 
  partly 
  to 
  the 
  difficulty 
  of 
  obtaining 
  specific 
  

   determinations 
  of 
  the 
  fossils 
  collected. 
  

  

  t 
  These 
  species 
  are 
  recorded 
  for 
  the 
  first 
  time. 
  Specific 
  names 
  in 
  brackets 
  

   indicate 
  that 
  the 
  determination 
  of 
  a 
  previous 
  autbor 
  has 
  been 
  used, 
  but 
  not 
  

   confirmed.
