  As 
  yet 
  I 
  have 
  met 
  with 
  only 
  one 
  instance 
  of 
  the 
  occurrence 
  of 
  

   this 
  coral 
  in 
  the 
  Inferior 
  Oolite. 
  It 
  was 
  taken, 
  by 
  Mr. 
  TT. 
  Jenkins 
  

   of 
  Cheltenham, 
  from 
  the 
  lower 
  reef 
  at 
  Crickley 
  Hill. 
  

  

  Compared 
  with 
  the 
  figure 
  given 
  by 
  M. 
  Lamouroux, 
  it 
  is 
  less 
  regu- 
  

   larly 
  turbinate, 
  being 
  more 
  depressed 
  and 
  having 
  the 
  upper 
  surface 
  

   more 
  convex. 
  But 
  in 
  the 
  number 
  and 
  distribution 
  of 
  the 
  calices, 
  

   and 
  in 
  the 
  thinness 
  and 
  delicacy 
  of 
  the 
  septa, 
  it 
  corresponds 
  with 
  

   great 
  accuracy, 
  with 
  the 
  figure 
  referred 
  to. 
  From 
  the 
  great 
  thin- 
  

   ness 
  of 
  the 
  septa 
  and 
  their 
  distance 
  apart, 
  the 
  interseptal 
  loculi 
  

   have 
  a 
  breadth 
  fully 
  twice 
  that 
  of 
  the 
  septa 
  themselves.

  It 
  is 
  with 
  great 
  doubt, 
  on 
  account 
  of 
  its 
  stouter 
  and 
  more 
  crooked 
  

   septa, 
  that 
  I 
  refer 
  this 
  species 
  to 
  the 
  M. 
  regularis 
  of 
  Edwards 
  and 
  

   Haime. 
  It 
  corresponds 
  much 
  more 
  closely 
  with 
  Michelin's 
  figure 
  

   than 
  with 
  that 
  given 
  by 
  Edwards 
  and 
  Haime 
  ; 
  but 
  when 
  the 
  septa 
  

   are 
  worn 
  down 
  they 
  appear 
  to 
  be 
  even 
  broader 
  than 
  in 
  his 
  figure, 
  

   and 
  the 
  interseptal 
  loculi 
  are 
  reduced 
  to 
  the 
  breadth 
  of 
  a 
  mere 
  line. 
  

  

  The 
  figures 
  given 
  respectively 
  by 
  Lamouroux 
  and 
  Michelin 
  of 
  

   M. 
  -porosa 
  and 
  Alveopont 
  microsolena 
  arc 
  clearly 
  those 
  of 
  two 
  

   distinct 
  species, 
  though 
  Edwards 
  and 
  Haime 
  give 
  the 
  latter 
  as 
  a 
  

   synonym 
  of 
  the 
  former. 
  It 
  is 
  doubtful 
  whether 
  M. 
  regularis 
  is 
  

   not 
  distinct 
  from 
  both. 
  That 
  the 
  present 
  species 
  is 
  identical 
  with 
  

   the 
  one 
  which 
  furnished 
  Michelin's 
  figure, 
  I 
  have 
  not, 
  however, 
  any 
  

   doubt. 
  

  

  Hitherto 
  I 
  have 
  only 
  met 
  with 
  it 
  from 
  the 
  Tric/onia-grit 
  at 
  

   Ravensgate 
  Hill, 
  where 
  it 
  is 
  not 
  uncommon.

  Several 
  fragments 
  of 
  a 
  species 
  quite 
  distinct 
  from 
  the 
  preceding, 
  

   and 
  probably 
  from 
  all 
  other 
  oolitic 
  species, 
  have 
  occurred 
  at 
  Crick- 
  

   ley. 
  They 
  are 
  characterized 
  by 
  their 
  extremely 
  rugged 
  and 
  crowded 
  

   septa, 
  and 
  by 
  the 
  obscurity 
  of 
  their 
  calices.

  The 
  examination 
  of 
  a 
  specimen 
  of 
  Dimorpliastrcea 
  from 
  the 
  

   Corallian 
  of

  which 
  I 
  at 
  first 
  supposed 
  to 
  be 
  the

  afterwards 
  found

  me 
  that

  referring

   species 
  to 
  it.
