  2. 
  Genera, 
  some 
  species 
  of 
  which 
  have 
  been 
  described 
  from 
  the 
  

   Miocene, 
  but 
  not 
  from 
  the 
  Eocene, 
  namely, 
  Dasyphyllia, 
  Antillia, 
  

   Isastrcea, 
  Cladocora. 
  

  

  3. 
  Genera, 
  some 
  species 
  of 
  which 
  have 
  been 
  described 
  as 
  Pliocene 
  

   and 
  Recent, 
  namely, 
  Agaricia, 
  Mycedium, 
  Cladocora, 
  Corallium. 
  

  

  The 
  single 
  species 
  which 
  I 
  have 
  mentioned 
  as 
  having 
  been 
  described 
  

   by 
  M. 
  Haime, 
  and 
  which 
  I 
  do 
  not 
  think 
  belongs 
  to 
  a 
  well-known 
  

   Eocene 
  genus, 
  has 
  so 
  great 
  a 
  resemblance 
  to 
  an 
  Antillia 
  of 
  the 
  Mio- 
  

   cene, 
  that 
  I 
  have 
  little 
  doubt 
  that 
  better 
  specimens 
  will 
  determine 
  

   it 
  not 
  to 
  be 
  a 
  Montlivaltia. 
  

  

  The 
  genus 
  Mycedium 
  is 
  now 
  noticed 
  for 
  the 
  first 
  time 
  as 
  fossil. 
  

   The 
  Cladocorce, 
  the 
  Oculina, 
  and 
  the 
  Corallium, 
  I 
  believe, 
  from 
  their 
  

   affinities 
  and 
  mineralization, 
  not 
  to 
  belong 
  to 
  either 
  a 
  Mid-tertiary 
  

   or 
  Nummulitic 
  age. 
  

  

  There 
  are 
  no 
  precedents 
  for 
  admitting 
  the 
  genera 
  of 
  the 
  second 
  

   division 
  into 
  the 
  Eocene, 
  and 
  there 
  are 
  abundant 
  evidences 
  of 
  a 
  

   Miocene 
  formation 
  in 
  Asia. 
  Milne-Edwards 
  and 
  Abich 
  have 
  de- 
  

   scribed 
  Miocene 
  species 
  of 
  Corals 
  from 
  the 
  Taurus 
  and 
  Upper 
  Asia 
  ; 
  

   Dr. 
  Carter 
  notices 
  a 
  Miliolitic 
  limestone 
  of 
  Miocene 
  age 
  over 
  the 
  

   Lower 
  Tertiary 
  formation 
  in 
  eastern 
  Arabia 
  ; 
  and 
  I 
  have 
  identified 
  

   Miocene 
  species 
  in 
  the 
  Loftus 
  Collection, 
  which 
  came 
  from 
  Persia, 
  

   and 
  also 
  amongst 
  some 
  fossils 
  from 
  Travancore. 
  

  

  In 
  conclusion, 
  I 
  arrange 
  the 
  undescribed 
  forms 
  as 
  follows 
  : 
  — 
  

   JNummulitic 
  — 
  Montlivaltia. 
  

  

  Miocene 
  — 
  Hydnophora, 
  Siderastrosa, 
  Astrosa, 
  Dasyphyllia, 
  

   Antillia, 
  Isastroza, 
  Agaricia, 
  Mycedium. 
  

  

  Pliocene 
  — 
  Cladocora, 
  Oculina, 
  Corallium. 
  — 
  [P. 
  M. 
  D.] 
  

  

  But 
  it 
  will 
  probably 
  be 
  remarked 
  that 
  the 
  range 
  in 
  time 
  of 
  the 
  

   different 
  genera 
  and 
  species 
  of 
  Corals 
  is 
  by 
  no 
  means 
  well 
  determined; 
  

   and 
  that 
  other 
  evidence 
  is 
  necessary 
  before 
  any 
  of 
  the 
  fossils 
  described 
  

   by 
  MM. 
  d'Archiac 
  and 
  Haime 
  can 
  be 
  referred 
  to 
  the 
  Miocene 
  period. 
  

   In 
  the 
  first 
  place, 
  it 
  may 
  be 
  observed 
  that 
  there 
  is, 
  amongst 
  palaeon- 
  

   tologists 
  and 
  geologists, 
  a 
  prejudice 
  against 
  Corals 
  as 
  evidences 
  of 
  

   the 
  age 
  of 
  strata; 
  but, 
  from 
  what 
  has 
  lately 
  been 
  done 
  by 
  Dr. 
  

   Duncan 
  and 
  others, 
  it 
  seems 
  to 
  me 
  that 
  this 
  prejudice 
  is 
  by 
  no 
  means 
  

   well 
  founded. 
  Moreover, 
  the 
  facts 
  just 
  stated 
  in 
  Dr. 
  Duncan's 
  note 
  

   are 
  too 
  many 
  and 
  too 
  weighty 
  to 
  be 
  explained 
  away 
  in 
  that 
  manner. 
  

  

  In 
  the 
  next 
  place, 
  although 
  it 
  is 
  not 
  now 
  my 
  intention 
  to 
  attempt 
  

   to 
  prove 
  that 
  any 
  of 
  the 
  beds 
  in 
  question 
  are 
  Miocene, 
  I 
  think 
  a 
  very 
  

   good 
  prima 
  facie 
  case, 
  suggesting 
  the 
  probability 
  of 
  some 
  of 
  them 
  

   being 
  of 
  that 
  age, 
  can 
  be 
  made 
  out 
  without 
  very 
  much 
  labour. 
  

  

  The 
  matrix 
  of 
  Vicarya 
  Verneuilii 
  is 
  stated 
  by 
  MM. 
  d'Archiac 
  and 
  

   Haime 
  to 
  be 
  a 
  "Calcaire 
  grisatre 
  avec 
  des 
  grains 
  de 
  fer 
  oxyde 
  hydrate." 
  

   Now, 
  very 
  few 
  fossils 
  are 
  stated 
  by 
  them 
  to 
  have 
  a 
  ferruginous 
  

   matrix 
  ; 
  and 
  it 
  is 
  appended 
  to 
  the 
  description 
  of 
  the 
  matrix 
  of 
  some 
  

   of 
  these, 
  that 
  it 
  is 
  very 
  different 
  from 
  that 
  of 
  the 
  greater 
  number 
  of 
  

   the 
  fossils 
  from 
  the 
  same 
  locality.

  four 
  known
