  This 
  singular 
  coral 
  strikes 
  one 
  at 
  first 
  sight 
  by 
  its 
  

   resemblance 
  to 
  some 
  of 
  the 
  members 
  of 
  the 
  group 
  uf 
  the 
  Rugosa. 
  A 
  closer 
  

   examination 
  tends 
  to 
  confirm 
  that 
  view. 
  The 
  septal 
  apparatus 
  is 
  subdi- 
  

   vided 
  into 
  Systems 
  that 
  are 
  multiples 
  of 
  four, 
  though 
  a 
  little 
  obscured 
  by 
  acci- 
  

   dental 
  causes. 
  Another, 
  though 
  perhaps 
  less 
  important, 
  character 
  is 
  the 
  

   smoothness 
  of 
  the 
  septa, 
  which 
  present 
  neither 
  perforations, 
  nor 
  synapti- 
  

   culae, 
  nor 
  granulations. 
  Tabulae, 
  hoAvever, 
  there 
  are 
  none, 
  the 
  inter- 
  

   septal 
  Chambers 
  being 
  open 
  from 
  top 
  to 
  bottom. 
  From 
  the 
  genus 
  Cya- 
  

   thaxonia 
  it 
  differs 
  in 
  being 
  attached 
  by 
  a 
  broad 
  base, 
  and 
  also 
  by 
  the 
  

   absence 
  of 
  a 
  septal 
  fossula. 
  

  

  Genus 
  Haplophyllia 
  PourtT. 
  

  

  Corallum 
  simple, 
  fixed 
  by 
  a 
  broad 
  base, 
  covered 
  with 
  a 
  thick 
  epitheca; 
  

   columella 
  styliform 
  , 
  strong, 
  (sometimes 
  double?; 
  very 
  thick 
  at 
  the 
  base. 
  

   Interseptal 
  Chambers 
  deep, 
  uninterrupted 
  by 
  tabulae 
  or 
  dissepimenta. 
  

  

  // 
  paradoxa. 
  Epitheca 
  thick 
  , 
  wrinkled 
  reaching 
  higher 
  than 
  the 
  

   calicle 
  and 
  forming 
  around 
  the 
  latter 
  several 
  concentric 
  circles. 
  Calicle 
  

   circular, 
  fossa 
  deep. 
  Septa 
  smooth, 
  not 
  reaching 
  the 
  border 
  of 
  the 
  calicle 
  ; 
  

   like 
  all 
  the 
  internal 
  parts 
  of 
  the 
  calicle, 
  their 
  surface 
  is 
  like 
  enamel. 
  

   Columella 
  formed 
  of 
  two 
  smooth 
  conical 
  processes, 
  very 
  thick 
  at 
  the 
  

   base 
  and 
  tending 
  to 
  fill 
  up 
  the 
  Chambers. 
  Eight 
  septa 
  larger, 
  and 
  con- 
  

   nected 
  with 
  the 
  columella, 
  alternating 
  with 
  smaller 
  ones, 
  which 
  touch 
  

   the 
  columella 
  at 
  a 
  much 
  lower 
  level. 
  A 
  further 
  cycle 
  is 
  indicated 
  by 
  

   small 
  ridges 
  of 
  the 
  wall 
  surface, 
  in 
  some 
  of 
  the 
  Chambers. 
  No 
  distinetion 
  

   can 
  be 
  made 
  between 
  primary 
  and 
  secondary 
  septa 
  among 
  the 
  eight 
  larger 
  

   ones 
  as 
  they 
  all 
  appear 
  equal. 
  This 
  arrangement 
  seems 
  to 
  be 
  the 
  norm. 
  

   In 
  the 
  speeimen 
  before 
  us, 
  unfortunately 
  the 
  only 
  one. 
  there 
  are 
  distur- 
  

   bances 
  in 
  two 
  of 
  the 
  Systems 
  or 
  half-systems 
  In 
  one 
  case 
  two 
  of 
  the 
  

   larger 
  septa 
  are 
  joined 
  by 
  a 
  horizontal 
  plate 
  at 
  the 
  top, 
  thus 
  excluding 
  

   the 
  intervening 
  Chamber 
  from 
  the 
  calicle. 
  This 
  strueture 
  is 
  probable 
  

   abnormal 
  and 
  the 
  result 
  of 
  an 
  effect 
  to 
  exclude 
  a 
  parasite 
  or 
  other 
  

   foreign 
  matter. 
  A 
  small 
  supernumerary 
  septum 
  has 
  grown 
  out 
  in 
  the 
  

   next 
  Chamber. 
  Nearly 
  on 
  the 
  opposite 
  side 
  of 
  the 
  calicle, 
  one 
  of 
  the 
  

   secondary 
  septa 
  (counting 
  eight 
  as 
  pn'maries) 
  has 
  grown 
  to 
  the 
  size 
  of 
  

   a 
  primary 
  one, 
  and 
  the 
  adjacent 
  tertiary 
  to 
  the 
  size 
  of 
  a 
  secondary, 
  

   thus 
  disturbing 
  the 
  symetry.
