  the 
  series. 
  South 
  of 
  the 
  pier 
  we 
  find 
  equally 
  large 
  masses 
  of 
  similar 
  

   rock, 
  transported 
  to 
  as 
  great 
  a 
  distance 
  and 
  to 
  a 
  still 
  more 
  elevated 
  

   position, 
  on 
  a 
  hill 
  composed 
  of 
  the 
  group 
  B'. 
  With 
  regard 
  to 
  the 
  

   distinction 
  that 
  I 
  have 
  made 
  between 
  B 
  and 
  B', 
  I 
  may 
  observe 
  that 
  

   I 
  have 
  not 
  found 
  any 
  strata 
  about 
  the 
  same 
  parallel 
  in 
  other 
  localities 
  

   so 
  strongly 
  marked 
  as 
  the 
  group 
  B 
  ; 
  so 
  that 
  I 
  am 
  disposed 
  to 
  con- 
  

   sider 
  the 
  peculiar 
  characteristics 
  of 
  B 
  as 
  local, 
  and 
  that 
  the 
  mark 
  (') 
  

   of 
  B' 
  may 
  be 
  dropped 
  when 
  the 
  group 
  is 
  regarded 
  as 
  typical. 
  

  

  From 
  the 
  position 
  of 
  B 
  and 
  B', 
  and 
  their 
  general 
  character, 
  I 
  have 
  

   inferred 
  that 
  these 
  members 
  of 
  the 
  series 
  are 
  our 
  approximate 
  equiva- 
  

   lent 
  of 
  the 
  Lower 
  Ludlow 
  ; 
  they 
  undoubtedly 
  lie 
  between 
  the 
  equi- 
  

   valents 
  of 
  the 
  Mayhill 
  Sandstone 
  and 
  of 
  the 
  Aymestry 
  Limestone. 
  B 
  

   of 
  our 
  section 
  is 
  generally 
  shaly, 
  sometimes 
  slaty 
  ; 
  it 
  is 
  exposed 
  on 
  the 
  

   shore 
  in 
  horizontal 
  and 
  vertical 
  sections, 
  and 
  also 
  in 
  a 
  small 
  brook 
  

   (Smith's 
  Brook) 
  which 
  passes 
  over 
  them 
  nearly 
  in 
  the 
  line 
  of 
  their 
  

   dip. 
  In 
  these 
  strata 
  the 
  organisms 
  often 
  form 
  thin 
  beds 
  of 
  lime- 
  

   stone 
  ; 
  they 
  are 
  sufficiently 
  numerous 
  as 
  individuals, 
  but 
  of 
  few 
  

   species 
  ; 
  the 
  variety 
  that 
  we 
  find 
  in 
  a 
  position 
  parallel 
  to 
  this 
  in 
  

   another 
  locality, 
  Merigonish, 
  being 
  here 
  wanting. 
  The 
  most 
  

   highly 
  developed 
  organism 
  that 
  I 
  found 
  here 
  is 
  the 
  Lamellibranch, 
  

   Grammysia 
  ; 
  it 
  here 
  makes 
  its 
  first 
  appearance 
  in 
  the 
  series. 
  In 
  the 
  

   following 
  table 
  the 
  principal 
  fossils 
  are 
  given: 
  — 
  

  

  Grammysia 
  triangulata, 
  Salt. 
  

  

  Grammysia 
  cingulata, 
  Hisinger. 
  

  

  Isocardia 
  ? 
  

  

  Strophomena 
  depressa, 
  Balm. 
  

  

  Orthis. 
  

  

  Chonetes. 
  

  

  Lin 
  g 
  ula. 
  

  

  Calymene. 
  

  

  Asaphus. 
  

  

  Crinoidea. 
  

  

  Tentaculites. 
  

  

  Graptolithus 
  Clintonensis, 
  Hall. 
  

  

  Bryozoa 
  ? 
  

  

  Worm-tracks. 
  

  

  Above 
  the 
  Graptolite-strata 
  there 
  occur 
  what 
  I 
  call 
  the 
  Crinoid- 
  

   and 
  Cornulite-strata, 
  the 
  lithological 
  characters 
  of 
  which, 
  as 
  well 
  as 
  

   their 
  fossils, 
  are 
  so 
  different 
  from 
  those 
  of 
  the 
  former 
  that 
  I 
  am 
  disposed 
  

   to 
  regard 
  this 
  as 
  the 
  commencement 
  of 
  the 
  group 
  C, 
  or 
  the 
  equi- 
  

   valent 
  of 
  the 
  Aymestry 
  Limestone. 
  The 
  strata 
  are 
  so 
  extremely 
  

   hard 
  that 
  it 
  is 
  in 
  general 
  very 
  difficult 
  to 
  extract 
  the 
  fossils 
  from 
  

   them. 
  A 
  distinguishing 
  feature 
  of 
  these 
  strata 
  is 
  the 
  abundance 
  of 
  

   Crinoidal 
  fragments 
  and 
  of 
  unusually 
  large 
  Cornulites. 
  It 
  is 
  from 
  

   them, 
  also, 
  that 
  I 
  suppose 
  we 
  derived 
  the 
  beautiful 
  Palceaster 
  which 
  

   was 
  found 
  in 
  a 
  water-worn 
  boulder 
  on 
  this 
  part 
  of 
  the 
  shore. 
  This 
  

   interesting 
  fossil, 
  which 
  I 
  gave 
  to 
  Dr. 
  Dawson, 
  is 
  now 
  in 
  his 
  col- 
  

   lection. 
  It 
  is 
  also 
  worthy 
  of 
  notice 
  that 
  the 
  genera 
  of 
  Mollusca 
  

   which, 
  existing 
  in 
  a, 
  had, 
  according 
  to 
  our 
  present 
  knowledge, 
  dis- 
  

   appeared 
  in 
  B 
  and 
  B' 
  of 
  this 
  locality, 
  reappear 
  in 
  these 
  strata. 
  It 
  

   is 
  also 
  the 
  earliest 
  stage 
  of 
  the 
  appearance 
  of 
  the 
  genus 
  Bellerophon 
  

   in 
  Nova 
  Scotia. 
  The 
  following 
  is 
  a 
  list 
  of 
  the 
  principal 
  fossils 
  :

  Bellerophon 
  trilobatus, 
  Sow.
