  Unfortunately, 
  no 
  fossils 
  have 
  been 
  found 
  yet 
  in 
  

   this 
  neighborhood 
  between 
  the 
  middle

  Diplograptus 
  

   amplexicaulis 
  beds 
  (see 
  stations 
  22-27) 
  or 
  the

  Dicellograptus 
  

   beds 
  of 
  Lansingburg 
  and

  Station 
  6. 
  Laveny's 
  point, 
  Waterford 
  

  

  This 
  locality 
  is 
  a 
  small 
  bluff 
  on 
  the' 
  west 
  bank 
  of 
  the 
  Hudson, 
  

   a 
  little 
  north 
  of 
  the 
  bridge 
  connecting 
  Waterford 
  and 
  Lansing- 
  

   burg. 
  Here 
  are 
  exposed 
  steeply 
  east 
  dipping 
  (50°, 
  n 
  110° 
  e) 
  

   intensely 
  black, 
  hard, 
  indurated, 
  argillaceous 
  slates, 
  overlain 
  a 
  

   little 
  farther 
  north 
  by 
  gray 
  arenaceous 
  and 
  micaceous 
  shales, 
  

   which 
  in 
  turn 
  underlie 
  alternating 
  sandstones 
  and 
  shales. 
  The 
  

   black 
  slate 
  was 
  found 
  to 
  contain: 
  

  

  Climacograptus 
  typicalis, 
  Hall 
  1 
  

  

  Diplograptus 
  putillus, 
  Hall 
  

  

  D. 
  spinulosus 
  sp. 
  n. 
  (a 
  colony 
  and 
  numerous 
  hydrorhabds) 
  

  

  Endoceras 
  proteiforme, 
  Hall 
  

  

  Climacograptus 
  typicalis 
  and 
  Diplograp- 
  

   tus 
  spinulosus 
  are 
  restricted 
  to 
  the 
  Utica 
  shale, 
  while 
  

   Diplograptus 
  putillus 
  finds 
  its 
  principal 
  development 
  

   in 
  that 
  terrane. 
  

  

  'Climacograptus 
  typicalis 
  is, 
  according 
  to 
  the 
  consensus 
  of 
  

   all 
  writers 
  on 
  the 
  Utica 
  and 
  Normans 
  kill 
  faunas, 
  restricted 
  to 
  the 
  Utica 
  

   shale 
  and 
  does 
  not 
  occur 
  in 
  the 
  latter 
  fauna. 
  The 
  only 
  exception 
  is 
  found 
  

   in 
  Freeh's 
  statement 
  (54:612) 
  that 
  he 
  has 
  seen 
  specimens 
  of 
  this 
  form 
  

   from 
  Normans 
  kill 
  in 
  the 
  Breslau 
  museum. 
  Freeh, 
  however, 
  also 
  considers 
  

   CI. 
  parvus 
  a 
  dwarf 
  form 
  of 
  CI. 
  typicalis, 
  basing 
  this 
  opinion 
  on 
  

   a 
  specimen 
  from 
  Cincinnati 
  in 
  the 
  same 
  museum. 
  As 
  C 
  1. 
  par 
  v 
  u 
  s 
  does 
  

   not 
  occur 
  at 
  Cincinnati, 
  but 
  is 
  restricted 
  to 
  the 
  Normans 
  kill 
  beds, 
  where 
  

   it 
  is 
  one 
  of 
  the 
  most 
  common 
  forms, 
  and 
  as 
  a 
  comparison 
  of 
  these 
  two 
  

   graptolites, 
  which 
  nowhere 
  occur 
  together, 
  shows 
  that 
  they 
  can 
  not 
  be 
  

   identical, 
  it 
  is 
  probable 
  that 
  he 
  did 
  not 
  recognize 
  the 
  two 
  forms, 
  and 
  his 
  

   CI. 
  typicalis 
  from 
  Normans 
  kill 
  is 
  only 
  a 
  somewhat 
  larger 
  specimen 
  

   of 
  C 
  1. 
  parvus. 
  

  

  Freeh 
  also 
  proposes 
  to 
  change 
  Hall's 
  adjective, 
  " 
  typicalis 
  " 
  to 
  " 
  typicus 
  " 
  

   on 
  the 
  ground 
  that 
  the 
  former 
  is 
  an 
  anglicism. 
  While 
  it 
  is 
  true 
  that 
  

   typicalis 
  is 
  not 
  a 
  word 
  of 
  classic 
  Latin 
  origin, 
  it 
  was 
  of 
  common 
  usage 
  In 
  

   later 
  Latin, 
  and, 
  as 
  many 
  very 
  expressive 
  words 
  have 
  been 
  taken 
  from 
  the 
  

   post-classic 
  Latin, 
  it 
  would 
  not 
  be 
  practical 
  to 
  deprive 
  the 
  paleontologlc 
  

   nomenclature 
  of 
  this 
  source 
  of 
  words 
  by 
  too 
  strict 
  philology.
