  exactly 
  like 
  that 
  of 
  Turritella 
  simplex, 
  which 
  is 
  closely 
  allied 
  to 
  T. 
  

   subangulata, 
  a 
  well-known 
  Miocene 
  species. 
  

  

  Knowing 
  that 
  Dr. 
  Duncan 
  had 
  been 
  recently 
  studying 
  the 
  Ter- 
  

   tiary 
  Corals, 
  I 
  asked 
  him 
  to 
  look 
  at 
  those 
  from 
  Scinde 
  in 
  the 
  Society's 
  

   collection, 
  with 
  a 
  view 
  of 
  ascertaining 
  whether 
  any 
  of 
  them 
  were 
  

   known 
  Miocene 
  species, 
  and, 
  as 
  a 
  result, 
  he 
  has 
  favoured 
  me 
  with 
  

   the 
  following 
  note, 
  which 
  is 
  inserted 
  here 
  with 
  his 
  permission

  Note 
  on 
  the 
  Scindian 
  Fossil 
  Corals.

  Martin 
  Duncan,

  The 
  Nummulitic 
  Coral-fauna 
  of 
  Scinde 
  will 
  always 
  be 
  associated 
  

   with 
  the 
  name 
  of 
  the 
  late 
  M. 
  Jules 
  Haime, 
  who 
  described 
  the 
  species 
  

   published 
  in 
  the 
  'Animaux 
  Fossiles 
  de 
  l'Inde.' 
  It 
  was 
  with 
  some 
  

   surprise 
  that 
  I 
  found, 
  on 
  examining 
  the 
  collection 
  of 
  Corals 
  which 
  

   had 
  passed 
  through 
  the 
  hands 
  of 
  MM. 
  d'Archiac 
  and 
  Haime, 
  many 
  

   species 
  undescribed; 
  and 
  also 
  that, 
  had 
  all 
  the 
  specimens 
  been 
  named, 
  

   a 
  very 
  different 
  aspect 
  would 
  have 
  been 
  given 
  to 
  the 
  whole. 
  The 
  

   Coral-fauna, 
  as 
  represented 
  by 
  the 
  whole 
  of 
  the 
  specimens 
  given 
  to 
  

   the 
  Society 
  by 
  Lieutenant 
  Blagrove, 
  consists 
  (1) 
  of 
  the 
  species 
  which 
  

   are 
  common 
  to 
  it 
  and 
  the 
  European 
  Nummulitic 
  formation 
  of 
  the 
  ma- 
  

   ritime 
  Alps, 
  — 
  the 
  fossils 
  of 
  these 
  distant 
  localities 
  being 
  often 
  barely 
  

   distinguishable, 
  on 
  account 
  of 
  their 
  mineralization 
  being 
  identical, 
  

   and 
  the 
  species 
  found 
  at 
  La 
  Palarea 
  being 
  very 
  well 
  represented 
  in 
  

   Scinde 
  ; 
  (2) 
  of 
  the 
  single 
  species 
  which 
  is 
  common 
  to 
  the 
  Eocene 
  of 
  

   north-western 
  Europe 
  and 
  to 
  the 
  Nummulitic 
  of 
  La 
  Palarea 
  — 
  the 
  

   Stylocoenia 
  emarciata 
  ; 
  (3) 
  of 
  species 
  peculiar 
  to 
  Scinde. 
  

  

  The 
  Corals 
  of 
  the 
  first 
  and 
  second 
  divisions 
  and 
  of 
  part 
  of 
  the 
  

   third 
  have 
  been 
  described 
  by 
  M. 
  Haime, 
  and, 
  with 
  one 
  exception, 
  

   they 
  belong 
  to 
  well-known 
  Eocene 
  genera 
  or 
  are 
  Eocene 
  species 
  ; 
  

   but 
  nearly 
  all 
  the 
  forms 
  remaining 
  in 
  the 
  third 
  division, 
  and 
  the 
  

   exceptional 
  instance 
  just 
  mentioned, 
  pertain 
  to 
  the 
  Miocene, 
  Plio- 
  

   cene, 
  and 
  Recent 
  Coral-faunae. 
  

  

  Either 
  these 
  specimens 
  came 
  from 
  the 
  same 
  strata 
  as 
  the 
  rest, 
  or 
  

   they 
  are 
  from 
  a 
  later 
  Tertiary 
  formation. 
  If 
  they 
  are 
  Nummulitic 
  

   (and 
  certainly 
  the 
  appearance 
  and 
  mineralization 
  of 
  some 
  of 
  them 
  is 
  

   like 
  that 
  of 
  the 
  species 
  described 
  as 
  such), 
  some 
  new 
  genera 
  and 
  

   some 
  new 
  species 
  of 
  old 
  genera 
  must 
  be 
  admitted 
  into 
  the 
  Eocene 
  

   period. 
  In 
  this 
  case 
  the 
  Scindian 
  Nummulitic 
  Coral-fauna 
  will, 
  

   without 
  any 
  known 
  Oligocene 
  affinities, 
  be 
  closely 
  allied 
  to 
  that 
  of 
  

   the 
  Mid-tertiary. 
  

  

  If, 
  however, 
  the 
  specimens 
  came 
  from 
  later 
  Tertiary 
  formations, 
  

   there 
  must 
  be 
  an 
  unrecognized 
  Miocene 
  and 
  probably 
  a 
  Subapennine 
  

   formation 
  in 
  Scinde. 
  

  

  I 
  recognize 
  amongst 
  the 
  undescribed 
  Corals 
  the 
  following 
  genera, 
  

   which 
  may 
  be 
  classified 
  thus 
  : 
  — 
  

  

  1. 
  Genera, 
  some 
  species 
  of 
  which 
  have 
  been 
  found 
  in 
  the 
  Eocene, 
  

   namely, 
  Hydnophora, 
  Montlivaltia, 
  Siderastrcea,Astrcea, 
  and 
  Oculina; 
  

   but 
  the 
  species 
  of 
  these 
  genera, 
  from 
  the 
  results 
  of 
  my 
  observations, 
  

   are 
  more 
  closely 
  allied 
  to 
  known 
  Miocene 
  and 
  Recent 
  forms 
  than 
  to 
  

   those 
  of 
  the 
  Eocene, 
  except 
  in 
  the 
  case 
  of 
  the 
  genus 
  Monilivaltia,
