  This 
  band 
  contained 
  Inoceram 
  MS-fragm 
  en 
  ts 
  in 
  large 
  quantity, 
  as 
  also 
  Spondylus 
  

   spinosus, 
  Sow., 
  Terebratula 
  carnea, 
  Sow., 
  and 
  Claris-spines 
  ; 
  Ostrea 
  semiplana, 
  

   Sow., 
  occurred 
  a 
  little 
  higher 
  up. 
  Vegetation 
  obscures 
  the 
  beds 
  below, 
  but 
  

   these 
  can 
  be 
  seen 
  to 
  consist 
  of 
  greenish-yellow 
  sands, 
  from 
  which 
  no 
  fossils 
  

   were 
  obtained. 
  

  

  Between 
  Glenarm 
  and 
  Carnlough 
  the 
  ground 
  is 
  very 
  much 
  broken, 
  

   landslips 
  having 
  taken 
  place 
  on 
  a 
  considerable 
  scale. 
  The 
  conditions 
  

   recall 
  those 
  observed 
  in 
  Islandmagee, 
  the 
  bed 
  with 
  green 
  sponge- 
  

   nodules, 
  of 
  the 
  Spongiarian 
  zone, 
  being 
  visible 
  in 
  one 
  quarry, 
  while 
  

   the 
  sponge-floor 
  with 
  Ventriculites 
  and 
  Coscinopora 
  is 
  also 
  probably 
  

   present. 
  

  

  Isolated 
  blocks 
  of 
  glauconitic 
  sandstone 
  were 
  also 
  found 
  

   by 
  us, 
  containing 
  pebbles 
  J 
  inch 
  in 
  diameter, 
  abundant 
  Inoceramus-' 
  

   fragments, 
  Terebratula 
  carnea, 
  Sow., 
  and 
  a 
  Bhynchonella 
  (possibly 
  

   plicatilis). 
  This 
  district 
  is 
  also 
  characterized 
  by 
  the 
  abundance 
  of 
  

   JSpondylus 
  spinosus, 
  Sow., 
  and 
  Ostrea 
  vesicularis, 
  Lam. 
  Gasteropoda, 
  

   such 
  as 
  Pleurotomaria 
  and 
  Turbo, 
  fishes 
  {Corax 
  maximus, 
  Lamna 
  

   acuminata, 
  Ag., 
  L. 
  appendiculata, 
  Ag., 
  and 
  Ptychodus 
  mammillaris, 
  

   Ag.), 
  and 
  several 
  species 
  of 
  Lima 
  have 
  also 
  been 
  recorded 
  by 
  the 
  

   Survey. 
  

  

  North 
  of 
  Garron 
  Point, 
  the 
  officers 
  of 
  the 
  Geological 
  Survey 
  

   record 
  two 
  exposures 
  of 
  glauconitic 
  conglomerate, 
  the 
  one 
  

   near 
  Milltown, 
  the 
  other 
  near 
  Retreat 
  Castle, 
  2 
  miles 
  south-west 
  of 
  

   Cushendall. 
  This 
  rock 
  (which 
  is 
  referred 
  to 
  the 
  Upper 
  Greensand 
  

   in 
  the 
  Geological 
  Survey 
  Memoir, 
  Expl. 
  Sheet 
  14) 
  is 
  described 
  as 
  

   a 
  bed 
  about 
  12 
  inches 
  thick, 
  composed 
  of 
  pebbles 
  of 
  vein-quartz 
  

   and 
  Lias 
  nodules, 
  in 
  a 
  glauconitic 
  (' 
  chloritic') 
  sand. 
  Terebratula 
  

   carnea, 
  Sow., 
  Inoceramus 
  sp., 
  Pecten 
  \JanircC\ 
  quinquecostatus, 
  Sow., 
  

   and 
  Lamna 
  appendiculata, 
  Ag., 
  are 
  the 
  principal 
  fossils. 
  It 
  will 
  

   thus 
  be 
  seen 
  that 
  it 
  is 
  probably 
  identical 
  with 
  the 
  rock 
  examined 
  

   by 
  us 
  at 
  Carnlough. 
  

  

  The 
  Eastern 
  Division 
  is 
  characterized 
  : 
  — 
  

  

  Zonally 
  : 
  

  

  1. 
  By 
  the 
  reduction 
  in 
  thickness, 
  or 
  total 
  absence, 
  of 
  the 
  zone 
  of 
  

  

  Eocogyra 
  columba. 
  

  

  2. 
  By 
  the 
  great 
  development 
  of 
  the 
  glauconitic 
  sandy 
  limestone 
  

  

  containing 
  fragments 
  of 
  Inocerami 
  and 
  JSpondylus 
  spinosus, 
  

   the 
  zone 
  of 
  Inoceramus 
  Crispi 
  of 
  Tate. 
  

  

  3. 
  By 
  the 
  presence 
  in 
  the 
  above 
  zone 
  of 
  definite 
  fossil-bands. 
  

  

  Palseontologically 
  : 
  

  

  4. 
  By 
  the 
  abundance, 
  in 
  the 
  Glauconitic 
  Sands, 
  of 
  Pecten 
  

  

  \_Clilamys~] 
  asper, 
  P. 
  Galliennei, 
  and 
  small 
  brachiopoda. 
  T 
  

  

  5. 
  By 
  the 
  frequent 
  occurrence 
  of 
  sea-urchins 
  in 
  the 
  Yellow 
  

  

  Sandstone 
  and 
  at 
  the 
  base 
  of 
  the 
  Chloritic 
  Sands. 
  

  

  6. 
  By 
  the 
  existence 
  of 
  a 
  Hexactinellid 
  sponge-floor 
  at 
  the 
  base 
  

  

  of 
  the 
  White 
  Limestone. 
  

  

  This 
  division 
  includes 
  Tate's 
  most 
  typical 
  sections, 
  and 
  it 
  is 
  here 
  

   that 
  Barrois 
  obtained 
  the 
  evidence 
  which 
  led 
  him 
  to 
  recognize 
  the
