  thirds 
  of 
  the 
  whole 
  height 
  of 
  the 
  corallurn. 
  It 
  is 
  attached 
  by 
  a 
  

   small 
  base 
  and 
  has 
  an 
  epitheca 
  which 
  is 
  thick 
  but 
  not 
  concentrically 
  

   wrinkled, 
  and 
  which 
  does 
  not 
  extend 
  to 
  the 
  margin 
  of 
  the 
  calice. 
  

  

  The 
  calice 
  is 
  elongated, 
  one 
  of 
  its 
  sides 
  being 
  nearly 
  straight 
  and 
  

   vertical, 
  while 
  the 
  other 
  is 
  rounded 
  and 
  bent 
  outwards. 
  It 
  is 
  deep, 
  

   and 
  although 
  elongated, 
  its 
  i'ossula 
  is 
  very 
  short, 
  being 
  almost 
  round. 
  

   The 
  margin 
  of 
  the 
  calice 
  is 
  more 
  or 
  less 
  expanded 
  and 
  everted 
  all 
  

   round. 
  

  

  The 
  septa 
  are 
  exsert, 
  but 
  they 
  slope 
  inwards 
  and 
  downwards 
  into 
  

   the 
  centre 
  of 
  the 
  calice 
  without 
  any 
  break 
  or 
  interruption. 
  They 
  

   are 
  alternately 
  large 
  and 
  small, 
  but 
  all 
  are 
  relatively 
  thick 
  at 
  their 
  

   outer 
  ends, 
  and 
  decrease 
  in 
  substance 
  evenly 
  as 
  they 
  approach 
  the 
  

   fossula, 
  where 
  they 
  meet 
  but 
  do 
  not 
  unite. 
  Their 
  margins 
  are 
  all 
  

   papillated, 
  but 
  not 
  very 
  regularly. 
  There 
  are 
  five 
  cycles 
  and 
  the 
  

   rudiments 
  of 
  a 
  sixth. 
  Those 
  of 
  the 
  first, 
  second, 
  and 
  third 
  cycles 
  

   are 
  nearly 
  of 
  a 
  length 
  ; 
  those 
  of 
  the 
  fourth 
  are 
  not 
  more 
  than 
  half 
  

   the 
  length 
  of 
  the 
  former 
  ; 
  and 
  those 
  of 
  the 
  fifth 
  are 
  quite 
  short.

  Three 
  occurrences 
  only 
  of 
  this 
  small 
  coral 
  have 
  come 
  to 
  my 
  know- 
  

   ledge. 
  Two 
  have 
  been 
  collected 
  from 
  the 
  Pisolite 
  at 
  Leckhampton, 
  

   and 
  one 
  from 
  very 
  near 
  the 
  sands 
  at 
  the 
  base 
  of 
  the 
  Inferior 
  Oolite 
  

   at 
  Dover's 
  Hill 
  near 
  Chipping

  Only 
  one 
  specimen 
  has 
  occurred 
  to 
  my 
  knowledge 
  in 
  the 
  Inferior 
  

   Oolite 
  of 
  Gloucestershire. 
  It 
  is 
  a 
  dead 
  one 
  and 
  partially 
  obscured 
  

   by 
  Serpulaa, 
  but 
  agrees 
  pretty 
  closely 
  with 
  Prof. 
  Duncan's 
  description 
  

   and 
  figure. 
  It 
  has 
  a 
  distinctly 
  peduncular 
  foot, 
  and 
  the 
  septa 
  meet 
  

   in 
  the 
  centre 
  of 
  the 
  calice 
  in 
  a 
  whorl. 
  It 
  only 
  differs 
  from 
  the 
  type 
  

   specimen 
  in 
  having 
  the 
  upper 
  part 
  of 
  the 
  corallurn 
  non-expanding, 
  

   but 
  of 
  a 
  cylindrico-ovoid 
  form 
  with 
  an 
  oval 
  calice. 
  

  

  It 
  was 
  found 
  by 
  me 
  in 
  the 
  Crickley 
  reef.

  A 
  Montlivcdtia 
  answering 
  well 
  to 
  the 
  figure 
  and 
  description 
  

   above 
  quoted 
  was 
  taken 
  by 
  me 
  from 
  the 
  compact 
  yellow 
  stone 
  which 
  

   lies 
  between 
  the 
  Pisolite 
  and

  A 
  single 
  ill-preserved 
  specimen 
  of 
  a 
  Montlivaltia, 
  having 
  all 
  the 
  

   calicular 
  peculiarities 
  mentioned 
  by 
  MM. 
  Edwards 
  and 
  Haime 
  as 
  

   characteristic 
  of 
  this 
  species, 
  was 
  given 
  to 
  me 
  with 
  a 
  large 
  number 
  

   of 
  rejected 
  corals 
  from 
  Crickley 
  by 
  Dr. 
  Wright 
  as 
  long 
  ago 
  as 
  1859, 
  

   but 
  remained 
  unnoticed 
  until 
  the 
  present 
  time. 
  

  

  The 
  large 
  septa 
  of 
  the 
  fifth 
  cycle 
  are 
  very 
  well 
  shown, 
  passing
