  so 
  as 
  to 
  present 
  much 
  the 
  appearance 
  of 
  a 
  series 
  of 
  rudimentary 
  

   inner 
  walls, 
  somewhat 
  as 
  in 
  Circophyllia. 
  The 
  central 
  part 
  of 
  the 
  

   calice 
  is 
  quite 
  free 
  from 
  dissepiments. 
  

  

  I 
  have 
  not 
  before 
  seen 
  the 
  peculiar 
  arrangement 
  of 
  the 
  septa 
  in 
  

   the 
  visceral 
  region 
  which 
  is 
  so 
  apparent 
  in 
  this 
  coral.

  Several 
  specimens 
  of 
  a 
  species 
  quite 
  distinct 
  from 
  the 
  last 
  have 
  

   been 
  taken 
  from 
  the 
  same 
  locality 
  and 
  from 
  the 
  same 
  bed, 
  which 
  

   appear 
  to 
  differ 
  from 
  Montlivaltice 
  in 
  having 
  smooth 
  septa, 
  which 
  

   are 
  alternately 
  thick 
  and 
  very 
  thin. 
  They 
  have 
  elongated 
  fossulae, 
  

   but 
  the 
  septa 
  do 
  uot 
  interlace, 
  and 
  the 
  dissepiments 
  are 
  feebly 
  de- 
  

   veloped 
  and 
  not 
  distributed 
  as 
  in 
  the 
  former 
  species.

  Portions 
  of 
  a 
  branching 
  coral 
  are 
  very 
  common 
  in 
  the 
  lower 
  and 
  

   middle 
  reefs 
  of 
  several 
  localities 
  in 
  Gloucestershire. 
  These, 
  by 
  

   comparison 
  with 
  specimens 
  of 
  Doiuicosmilia 
  corallina 
  received 
  from 
  

   M. 
  de 
  Fromentel 
  have 
  been 
  satisfactorily 
  determined 
  as 
  appertain- 
  

   ing 
  to 
  that 
  genus. 
  It 
  is 
  characterized 
  by 
  growth 
  by 
  lateral 
  gem- 
  

   mation, 
  and 
  by 
  septa 
  which 
  have 
  their 
  margins 
  entire. 
  It 
  is 
  most 
  

   frequently 
  met 
  with 
  in 
  single 
  joints, 
  which 
  may 
  show 
  periods 
  of 
  

   growth 
  or 
  not. 
  These 
  have 
  been 
  respectively 
  described 
  by 
  Prof. 
  

   Duncan 
  as 
  Monilivaltia 
  l/olli, 
  and 
  by 
  MM. 
  Edwards 
  and 
  Haime 
  as 
  

   Accosmilia 
  Wrigliti. 
  The 
  latter 
  specific 
  name 
  must 
  have 
  the 
  pre- 
  

   cedence. 
  

  

  It 
  will 
  not 
  be 
  necessary 
  to 
  add 
  to 
  the 
  descriptions 
  already 
  pub- 
  

   lished 
  by 
  those 
  zoophytologists, 
  excepting 
  to 
  state 
  that 
  it 
  is 
  a 
  tall 
  

   species, 
  the 
  branches 
  of 
  which 
  are 
  united 
  to 
  the 
  larger 
  stems 
  by 
  so 
  

   small 
  a 
  point 
  of 
  attachment 
  that 
  they 
  are 
  readily 
  broken 
  off, 
  and 
  the 
  

   acquisition 
  of 
  any 
  thing 
  like 
  complete 
  specimens, 
  except 
  when 
  im- 
  

   bedded 
  in 
  matrix, 
  is 
  very 
  difficult. 
  

  

  This 
  species 
  occurs 
  commonly 
  in 
  the 
  lower 
  reef 
  at 
  Crickley 
  Hill, 
  

   the 
  hill 
  above 
  the 
  Horse 
  Pools, 
  and 
  near 
  Cooper's 
  Hill, 
  and 
  in 
  the 
  

   middle 
  reef 
  at 
  Leckhampton 
  Hill 
  and 
  Painswick 
  ; 
  but 
  I 
  have 
  not 
  yet 
  

   met 
  with 
  a 
  single 
  fragment 
  from 
  the 
  upper 
  reef. 
  

  

  I 
  am 
  indebted 
  to 
  Dr. 
  Wright 
  for 
  the 
  opportunity 
  of 
  examining 
  

   the 
  types 
  of 
  Axosmilia 
  Wrigliti, 
  and 
  to 
  Dr. 
  Holl 
  for 
  the 
  use 
  of 
  the 
  

   specimens 
  of 
  Montlivaltia 
  Holli, 
  figured 
  and 
  described 
  by 
  Prof. 
  

   Duncan. 
  The 
  comparison 
  of 
  numerous 
  specimens 
  with 
  these 
  leaves 
  

   no 
  doubt 
  as 
  to 
  the 
  correctness 
  of 
  my 
  determination. 
  

  

  Since 
  the 
  publication 
  of 
  my 
  paper 
  on 
  the 
  Crickley 
  Corals, 
  I 
  have 
  

   entertained 
  great 
  doubts 
  whether 
  the 
  species 
  there 
  referred 
  to, 
  the 
  

   Thecosmilia 
  Wrigliti 
  of 
  Duncan, 
  was 
  any 
  thing 
  more 
  than 
  portions 
  

   of 
  Donacosmilia 
  Wrigliti 
  which 
  had 
  attained 
  to 
  a 
  greater 
  size 
  than 
  

   usual 
  ; 
  and 
  I 
  was 
  led 
  to 
  entertain 
  that 
  suspicion 
  in 
  consequence 
  of
