   this

  Inferior-Oolite 
  species, 
  and 
  now, 
  on 
  the 
  evidence 
  of 
  

   two 
  specimens, 
  add 
  it 
  to 
  the 
  list 
  of 
  Gloucestershire 
  species. 
  One 
  

   of 
  them 
  is 
  in 
  the 
  collection 
  of 
  Dr. 
  Wright, 
  and 
  the 
  other 
  in 
  my 
  

   own. 
  The 
  latter 
  was 
  taken 
  by 
  me 
  from 
  the 
  debris 
  in 
  a 
  cavity 
  in

  The 
  examples 
  of 
  this 
  species 
  which 
  I 
  examined 
  before 
  writing 
  

   my 
  paper 
  on 
  " 
  The 
  Crickley 
  Hill 
  Corals," 
  were, 
  there 
  is 
  no 
  longer 
  

   any 
  doubt, 
  referable 
  to 
  another 
  genus, 
  and 
  are 
  now 
  described 
  as 
  a 
  

   Confusastrcea. 
  But 
  other 
  specimens 
  have 
  occurred 
  which 
  are 
  un- 
  

   doubtedly 
  referable 
  to 
  M'Coy's 
  Astrcea 
  tenuistriata. 
  In 
  his 
  descrip- 
  

   tion 
  he 
  says, 
  " 
  centre 
  obscurely 
  granular 
  ;" 
  and 
  in 
  some 
  specimens 
  

   from 
  the 
  Trigonia-grit 
  at 
  llavensgate 
  Hill 
  I 
  have 
  observed 
  this 
  

   peculiarity 
  sufficiently 
  pronounced 
  to 
  almost 
  assume 
  the 
  appearance 
  

   of 
  a 
  papillose 
  columella. 
  I 
  have 
  not 
  hesitated, 
  therefore, 
  to 
  reform
