﻿ANNIVERSARY 
  ADDRESS 
  OF 
  THE 
  PRESIDENT. 
  

  

  177 
  

  

  The 
  remarkable 
  cones 
  Aroides 
  Stutterdi, 
  Carr., 
  and 
  Kaidaearpum 
  

   ooliticum, 
  Carr., 
  are 
  both 
  from 
  these 
  beds 
  at 
  Stonesfield. 
  

  

  This 
  exhausts 
  the 
  flora 
  of 
  the 
  Jurassic 
  rocks 
  proper, 
  or 
  from 
  the 
  

   base 
  of 
  the 
  Inferior 
  Oolite 
  to 
  the 
  Portland, 
  in 
  the 
  latter 
  of 
  which 
  I 
  

   know 
  of 
  no 
  recorded 
  plant-remains 
  except 
  wood. 
  

  

  The 
  accompanying 
  small 
  Table 
  (XXVII.) 
  will 
  show 
  the 
  number 
  

   of 
  genera 
  and 
  species 
  in 
  the 
  10 
  divisions 
  of 
  the 
  English 
  and 
  Scotch 
  

   Oolitic 
  Rocks.

  None 
  pass

  the 
  Lias 
  to 
  the 
  Inferior 
  Oolite 
  ; 
  and 
  none 
  in 
  higher 
  

   beds 
  are 
  common 
  to 
  more 
  than 
  one 
  deposit. 
  

  

  Amorphozoa. 
  — 
  None. 
  

  

  Coslenteeata. 
  — 
  Actinozoa. 
  — 
  I 
  have 
  stated 
  that 
  38 
  genera 
  and 
  715 
  

   species 
  constitute 
  the 
  entire 
  Ccelenterate 
  fauna 
  of 
  the 
  Jurassic 
  rocks. 
  

   The 
  Lias 
  I 
  have 
  discussed 
  (vide 
  Table 
  XXVI., 
  p. 
  175). 
  The 
  Actinozoa 
  

   of 
  the 
  Inferior 
  Oolite 
  stand 
  almost 
  alone, 
  its 
  48 
  species 
  being, 
  with 
  but 
  

   few 
  exceptions, 
  confined 
  to 
  it. 
  The 
  only 
  species 
  that 
  pass 
  to 
  higher 
  

   beds 
  are 
  Anabacia 
  hemisphcerica, 
  A. 
  orbulites, 
  Gomoseris 
  vermicularis, 
  

   Isastrcea 
  explanata, 
  I. 
  explanidata, 
  I. 
  limitata, 
  Monti 
  ivaltia 
  Delahechei. 
  

   M. 
  tenuilamellosa, 
  Stylina 
  solida, 
  and 
  Thamnastrcea 
  concinna. 
  Eight 
  

   of 
  these 
  10 
  do 
  not 
  pass 
  beyond 
  the 
  Great 
  Oolite, 
  the 
  species 
  having 
  

   the 
  longer 
  range 
  being 
  Isastrcea 
  explanata,which. 
  is 
  common, 
  if 
  rightly 
  

   determined, 
  to 
  both 
  the 
  Inferior 
  Oolite 
  and 
  the 
  Coral 
  Eag, 
  and. 
  Ana- 
  

   bacia 
  orbulites, 
  which 
  occurs 
  in 
  the 
  Forest 
  Marble, 
  Cornbrash, 
  and 
  

   Corallian 
  beds. 
  Thus, 
  out 
  of 
  the 
  19 
  genera 
  and 
  48 
  species 
  that 
  com- 
  

   mence 
  in 
  the 
  limestones 
  of 
  the 
  Inferior 
  Oolite, 
  2 
  genera 
  and 
  3 
  species 
  

   pass 
  to 
  the 
  Fuller's 
  Earth, 
  5 
  genera 
  and 
  7 
  species 
  to 
  the 
  Great 
  Oolite. 
  

   Except 
  in 
  the 
  case 
  of 
  the 
  .Mollusca, 
  and 
  that 
  in 
  a 
  minor 
  degree 
  (vide 
  

   Table 
  XXXL, 
  p. 
  188), 
  the 
  community 
  of 
  species 
  between 
  the 
  lowest 
  

   beds 
  of 
  the 
  Oolitic 
  series 
  and 
  the 
  succeeding 
  9 
  horizons 
  is 
  small. 
  

   With 
  the 
  exception 
  of 
  the 
  Isastrcea} 
  and 
  Tliamnastrcece, 
  most 
  of 
  the 
  

   Corals 
  are 
  simple 
  forms, 
  e. 
  g. 
  Montlivaltia, 
  Anabacia, 
  Cydolites, 
  

   Trochocyaihus, 
  &c. 
  In 
  Yorkshire 
  but 
  few 
  species 
  occur 
  in 
  the 
  

   Inferior 
  Oolite, 
  Gonioseris 
  angulata, 
  G. 
  Leclcenbyi, 
  and 
  Montlivaltia 
  

   convexa 
  being 
  all 
  that 
  are 
  known. 
  \Ve 
  must 
  see 
  the 
  grandly 
  

   developed 
  Oolites 
  of 
  the 
  Cotteswolds 
  for 
  the 
  more 
  prolific 
  Coral- 
  

   liferous 
  deposits.
