  of 
  the 
  co. 
  Antrim 
  from 
  Colin 
  Glen 
  to 
  Whitehead, 
  also 
  on 
  the 
  Carrick- 
  

   fergus 
  Commons, 
  and 
  on 
  the 
  shores 
  of 
  Lough 
  Morne 
  ; 
  on 
  the 
  east, 
  

   around 
  the 
  shores 
  of 
  Larne 
  Lough 
  and 
  on 
  the 
  east 
  coast 
  of 
  Island 
  

   Magee, 
  Larne, 
  Glenarm, 
  and 
  Garron 
  Point; 
  on 
  the 
  north, 
  at 
  Bal- 
  

   lintoy 
  and 
  Portrush 
  ; 
  and 
  in 
  the 
  co. 
  Londonderry, 
  at 
  Magilligan, 
  on 
  

   the 
  IST.E., 
  Aghanloo, 
  and 
  Lisnagrib 
  ; 
  so 
  that 
  it 
  occupies 
  a 
  consider- 
  

   able 
  area 
  in 
  the 
  N.E. 
  of 
  Ireland. 
  The 
  last 
  two 
  localities 
  are 
  men- 
  

   tioned 
  by 
  Portlock. 
  

  

  The 
  zone 
  of 
  the 
  White 
  Lias 
  and 
  the 
  Avicula-contorta 
  beds 
  pro- 
  

   bably 
  occur 
  in 
  all 
  cases 
  below 
  the 
  Lower 
  Lias, 
  or 
  even 
  where 
  a 
  

   limited 
  amount 
  of 
  denudation 
  has 
  occurred, 
  removing 
  only 
  the 
  super- 
  

   incumbent 
  beds. 
  The 
  White 
  Lias 
  has 
  been 
  observed 
  at 
  Colin 
  Glen, 
  

   Cave 
  Hill, 
  and 
  Larne. 
  

  

  The 
  Avicula-contorta 
  zone 
  I 
  have 
  traced 
  from 
  Colin 
  Glen 
  to 
  White- 
  

   head 
  and 
  Larne 
  ; 
  at 
  Lisnagrib 
  and 
  Derrymore 
  it 
  was 
  observed 
  by 
  

   Portlock. 
  

  

  Notes 
  on 
  Species. 
  

   Dentalium 
  minimum, 
  Strickland. 
  

  

  This 
  minute 
  Dentalium 
  was 
  first 
  described, 
  but 
  not 
  figured, 
  by 
  Port- 
  

   lock 
  (Geol. 
  Report, 
  Londonderry, 
  1843) 
  as 
  D. 
  tenue, 
  a 
  specific 
  name 
  

   preoccupied 
  by 
  a 
  Dentalium 
  figured 
  by 
  Goldfuss, 
  to 
  which 
  species 
  

   Portlock's 
  shell 
  is 
  not 
  referable. 
  

  

  Strickland, 
  in 
  the 
  ' 
  Geology 
  of 
  Cheltenham' 
  (1845, 
  p. 
  101), 
  de- 
  

   scribes, 
  without 
  a 
  figure, 
  the 
  same 
  species 
  from 
  the 
  Lower 
  Lias 
  of 
  

   Cracombe 
  as 
  D. 
  minimum. 
  

  

  D. 
  minimum 
  I 
  have 
  found 
  pretty 
  frequently 
  on 
  the 
  west 
  shore 
  of 
  

   Island 
  Magee, 
  co. 
  Antrim. 
  I 
  have 
  also 
  obtained 
  it 
  in 
  great 
  abun- 
  

   dance 
  in 
  the 
  Lower 
  Lias 
  clay-pits 
  off 
  the 
  Leckhampton 
  Road, 
  Chel- 
  

   tenham. 
  The 
  Irish 
  examples 
  are 
  less 
  curved 
  and 
  elongated 
  and 
  

   more 
  slender 
  than 
  the 
  Cheltenham 
  forms.

  This 
  Coral, 
  new 
  to 
  British 
  palaeontology, 
  has 
  been 
  determined 
  by 
  

   Dr. 
  P. 
  M. 
  Duncan. 
  

  

  It 
  was 
  called 
  Cyclolites 
  granulatus 
  by 
  Quenstedt, 
  Handb. 
  der 
  Petref. 
  

   p. 
  658, 
  pi.

  fig. 
  21, 
  1862 
  ; 
  but 
  it 
  is 
  not 
  the 
  Montlivaltia 
  granu- 
  

   lata 
  of 
  Edwards 
  and 
  Haime, 
  1851, 
  which 
  is 
  from 
  the 
  St. 
  Cassian 
  

   Beds, 
  and 
  which 
  was 
  originally 
  described 
  as 
  Cyathophyllum 
  granu- 
  

   latum 
  by 
  Miinster, 
  1841, 
  and 
  afterwards 
  as 
  Tliecophyllia 
  granulata 
  

   by 
  D'Orbigny 
  in 
  1850. 
  

  

  Montlivaltia 
  Haimei 
  occurs 
  at 
  Jamoigne, 
  in 
  the 
  Belgian 
  Lower 
  

   Lias. 
  

  

  I 
  have 
  found 
  it 
  not 
  unfrequently 
  on 
  the 
  east 
  shore 
  of 
  Larne 
  Lough, 
  

   also 
  at 
  Waterloo, 
  Larne 
  ; 
  and 
  it 
  has 
  also 
  been 
  found 
  by 
  my 
  friend 
  

   Mr. 
  Gray 
  between 
  Larne 
  and 
  Ballylig, 
  on 
  the 
  west 
  shore 
  of 
  Larne 
  

   Lough. 
  Specimens 
  in 
  the 
  Belfast 
  Museum 
  are 
  labelled 
  BaEintoy, 
  

   on 
  the 
  north 
  coast 
  of 
  Antrim. 
  It 
  thus 
  appears 
  to 
  be 
  a 
  somewhat 
  

   widely 
  distributed 
  and 
  not 
  uncommon 
  Coral.
