  ON 
  THE 
  

  

  Astarte 
  senecta, 
  Bean, 
  MS. 
  

  

  This 
  Astarte 
  seems 
  to 
  have 
  been 
  identified 
  with 
  A. 
  laticosta, 
  

   Deshayes, 
  but 
  it 
  is 
  very 
  doubtful 
  if 
  this 
  determination 
  is 
  correct. 
  

   It 
  is 
  confined 
  at 
  Speeton 
  to 
  a 
  certain 
  part 
  of 
  the 
  zone 
  of 
  Bel. 
  late- 
  

   ralis 
  ; 
  and, 
  though 
  common 
  there, 
  being 
  incrusted 
  in 
  rapidly 
  decom- 
  

   posing 
  pyrites, 
  it 
  is 
  difficult 
  to 
  obtain 
  serviceable 
  specimens. 
  The 
  

   same 
  species 
  occurs 
  in 
  the 
  Lincolnshire 
  area. 
  The 
  name 
  is 
  some- 
  

   times 
  misprinted 
  Astarte 
  sinuata. 
  

  

  IsOCARDIA 
  ANGULATA, 
  Phil. 
  

  

  This 
  small 
  shell, 
  which 
  is 
  very 
  abundant 
  at 
  Speeton, 
  has 
  a 
  wide 
  

   range, 
  occurring 
  in 
  all 
  except 
  the 
  lowest 
  beds 
  of 
  the 
  zone 
  of 
  Bel. 
  

   jaculum 
  and 
  ranging 
  upwards 
  throughout 
  the 
  greater 
  part 
  of 
  the 
  

   zone 
  of 
  Bel.

  ? 
  

  

  Echinospatangus 
  cordiformis,

  I 
  have 
  already 
  recorded 
  the 
  horizons 
  at 
  which 
  I 
  have 
  found 
  this 
  

   fossil. 
  The 
  condition 
  of 
  its 
  preservation 
  — 
  coated 
  and 
  sometimes 
  

   quite 
  concealed 
  by 
  pyrites, 
  in 
  beds 
  in 
  which 
  small 
  concretions 
  of 
  

   pyrites 
  abound 
  — 
  makes 
  it 
  very 
  difficult 
  to 
  detect, 
  and 
  further 
  re- 
  

   searches 
  may 
  extend 
  its 
  range. 
  I 
  believe 
  the 
  position 
  now 
  assigned 
  

   to 
  it 
  at 
  Speeton 
  will 
  bring 
  that 
  section 
  into 
  closer 
  accordance 
  with 
  

   the 
  Neocomian 
  beds 
  of 
  Prance 
  and 
  Switzerland. 
  

  

  Pentacrinus 
  (annul 
  attjs, 
  Romer). 
  

  

  This 
  Crinoicl 
  occurs 
  plentifully 
  in 
  the 
  Compound 
  Nodular 
  Band, 
  in 
  

   detached 
  fragments, 
  and 
  also 
  in 
  the 
  JSforicus-beds, 
  but 
  I 
  have 
  not 
  

   yet 
  found 
  it 
  higher 
  in 
  the 
  section. 
  

  

  Trochocyathus 
  conulus, 
  Phil. 
  

  

  The 
  small 
  coral 
  which 
  has 
  been 
  with 
  some 
  doubt 
  referred 
  to 
  this 
  

   Gault 
  species 
  occurs 
  throughout 
  the 
  Noricus-heds, 
  where, 
  however, 
  

   it 
  is 
  rare. 
  I 
  have 
  not 
  seen 
  it 
  in 
  any 
  other 
  part 
  of 
  the 
  section. 
  

  

  Foraminieera 
  are 
  very 
  plentiful 
  in 
  many 
  of 
  the 
  beds 
  (especially 
  

   in 
  Dl, 
  C 
  8, 
  C6, 
  C3, 
  and 
  in 
  parts 
  of 
  B), 
  but 
  I 
  am 
  not 
  aware 
  that 
  

   any 
  work 
  has 
  yet 
  been 
  done 
  on 
  them. 
  

  

  Crustacea. 
  

  

  I 
  am 
  indebted 
  to 
  Dr. 
  James 
  Carter 
  for 
  the 
  following 
  notes 
  on 
  the 
  

   specimens 
  from 
  my 
  collection 
  submitted 
  to 
  him.

  ornata,

  " 
  Of 
  this 
  characteristic 
  and 
  beautiful 
  species 
  I 
  can 
  give 
  but 
  little 
  

   additional 
  information. 
  It 
  is 
  desirable 
  to 
  ascertain 
  the 
  conforma- 
  

   tion 
  of 
  the 
  chelae 
  of 
  the 
  first 
  pair 
  of 
  limbs 
  — 
  whether 
  they 
  are 
  mono- 
  

   or 
  didactylous.
