  differs

  having 
  much 
  smaller

  The

  also 
  much 
  more

   probably 
  porous

  the

  Mr. 
  W. 
  Jenkins, 
  of 
  Cheltenham, 
  has 
  forwarded 
  to 
  me 
  a 
  specimen 
  

   of 
  this 
  species 
  which 
  he 
  obtained 
  from 
  the 
  lower 
  reef 
  at 
  Crickley, 
  

   which 
  agrees 
  with 
  the 
  specimens 
  figured 
  by 
  MM. 
  Edwards 
  and 
  

   Haime, 
  except 
  that 
  the 
  ridges 
  are 
  straighter 
  and 
  less 
  numerous 
  

   than 
  they 
  are 
  represented 
  to 
  be 
  in 
  the 
  figures 
  given 
  by 
  those 
  cele- 
  

   brated 
  zoophytologists. 
  There 
  is 
  a 
  specimen 
  also 
  in 
  Dr. 
  Wright's 
  

   collection.

  Since 
  the 
  foregoing 
  was 
  written 
  I 
  have 
  examined 
  a 
  large 
  number 
  

   of 
  corals 
  from 
  the 
  Great 
  Oolite 
  near 
  Cirencester, 
  amongst 
  which 
  were 
  

   some 
  specimens 
  of 
  Thecosmilia 
  obtusa 
  ; 
  and 
  I 
  find 
  that 
  these 
  agree 
  

   closely 
  with 
  some 
  others 
  from 
  the 
  IVigonia-grit 
  at 
  Birdlip 
  and 
  

   Leckhampton 
  Hill. 
  Probably 
  the 
  specimens 
  which 
  I 
  made 
  use 
  of 
  

   for 
  comparison 
  were 
  a 
  part 
  of 
  the 
  same 
  collection 
  which 
  furnished 
  

   Prof. 
  Duncan 
  with 
  the 
  specimen 
  from 
  which 
  his 
  figure 
  was 
  taken*. 
  

  

  The 
  occurrence 
  of 
  this 
  species 
  in 
  the 
  upper 
  corallif 
  erous 
  bed 
  of 
  the 
  

   Inferior 
  Oolite, 
  as 
  well 
  as 
  in 
  the 
  Great 
  Oolite, 
  furnishes 
  additional 
  

   evidence 
  of 
  what 
  Dr. 
  Wright 
  has 
  advanced 
  respecting 
  their 
  near 
  

   paheontological 
  relationship. 
  

  

  It 
  appears 
  to 
  be 
  to 
  corals 
  of 
  this 
  group 
  that 
  Quenstedt 
  has 
  

   applied 
  the 
  generic 
  name 
  Coenotheca. 
  Their 
  mode 
  of 
  increase, 
  how- 
  

   ever, 
  which 
  is 
  wholly 
  by 
  gemmation, 
  does 
  not 
  differ 
  from 
  that 
  of 
  the 
  

   allied 
  or 
  perhaps 
  identical 
  Chorisastrcea 
  gregaria, 
  and 
  both 
  must 
  be 
  

   referred 
  to 
  the 
  same 
  genus. 
  

  

  In 
  conclusion 
  I 
  wish 
  particularly 
  to 
  acknowledge 
  the 
  great 
  

   assistance 
  I 
  have 
  met 
  with 
  at 
  the 
  hands 
  of 
  friends 
  when 
  preparing 
  

   the 
  present 
  paper.
