  Pulaski 
  and 
  other 
  places 
  in 
  New

  2. 
  The 
  Medina 
  Sandstone 
  is 
  represented 
  by 
  a 
  few 
  fossils 
  only. 
  

  

  3. 
  The 
  Clinton 
  Group 
  is 
  largely 
  represented 
  by 
  the 
  characteristic 
  

  

  fossils 
  which 
  occur 
  in 
  New 
  York. 
  

  

  4. 
  The 
  Niagara 
  Group 
  is 
  largely 
  represented. 
  There 
  are 
  many 
  

  

  fine 
  Corals 
  and 
  Bryozoans, 
  and 
  of 
  the 
  latter 
  some 
  remarkably 
  

   fine 
  specimens, 
  particularly 
  of 
  the 
  genera 
  Callopora 
  and 
  

   Trematopora. 
  

  

  There 
  are 
  several 
  specimens 
  of 
  Encalyptocrinus, 
  Stepha- 
  

   nocrinus, 
  etc., 
  and 
  a 
  fine

  6. 
  The 
  Upper 
  Helderberg 
  Group 
  is 
  mainly 
  represented 
  by 
  Corals. 
  

  

  Many 
  of 
  these 
  have 
  been 
  worked 
  out 
  by 
  acids, 
  so 
  as 
  to 
  be 
  

   almost 
  entirely 
  free 
  from 
  adhering 
  stone, 
  leaving 
  the 
  silicified 
  

   corals 
  in 
  fine 
  condition. 
  

  

  There 
  are 
  also 
  a 
  few 
  Brachiopoda 
  and 
  Lamellibranchiata, 
  

   Cephalopoda, 
  Bryozoa 
  and 
  Crustacea. 
  

  

  7. 
  The 
  Hamilton 
  Group 
  is 
  largely

  by 
  the 
  fossils 
  of 
  

  

  Western 
  New 
  York 
  in 
  all 
  the 
  different 
  classes. 
  The 
  most 
  

   conspicuous 
  and 
  important 
  of 
  these 
  are 
  the 
  Crinoidea, 
  of 
  

   which 
  there 
  are 
  many 
  fine 
  specimens 
  of 
  several 
  genera 
  and 
  

   species. 
  Of 
  Actinocrinus 
  eucharis 
  (of 
  which 
  but 
  one 
  speci- 
  

   men 
  has 
  been 
  seen 
  by 
  me 
  before) 
  there 
  are 
  three 
  -or 
  four. 
  

   There 
  are 
  also 
  specimens 
  of 
  Megistocrinus, 
  Cacabocrinus, 
  

   Poteriocrinus, 
  and 
  one 
  new 
  species 
  of 
  Uliodoerinus 
  of 
  re- 
  

   markable 
  character.

  which 
  are 
  rare,

  fine 
  slabs 
  

   of 
  Filieites 
  (fossil 
  ferns). 
  

  

  9. 
  The 
  Burlington 
  Limestone 
  is 
  represented 
  by 
  a 
  considerable 
  

  

  number

  ordinary 
  character.
