   Corynoides 
  calicularis 
  Nicholson, 
  which 
  occurs 
  in 
  the 
  Scot- 
  

   tish 
  Hartfell 
  and 
  Glenkiln 
  shales 
  was 
  recognized 
  by 
  Lapworth 
  in 
  the 
  

   Canadian 
  Dicellograptus 
  zones 
  and 
  is 
  the 
  only 
  species 
  of 
  Corynoides 
  

   mentioned 
  by 
  him 
  and 
  Dr 
  Gurley 
  from 
  America. 
  It 
  is 
  also 
  very 
  common 
  

   in 
  the 
  Normans 
  kill 
  shale, 
  and 
  was 
  figured 
  by 
  Hall 
  among 
  the 
  " 
  germs 
  ", 
  

   evidently 
  on 
  account 
  of 
  its 
  similarity 
  with 
  the 
  sicula 
  (Decade

  While 
  

   Corynoides 
  calicularis 
  is 
  apparently 
  restricted 
  to 
  the 
  Dicello- 
  

   graptus 
  zones, 
  and

  not 
  continue 
  to

  another 
  form, 
  

   only 
  half 
  as 
  long, 
  much 
  stouter 
  and 
  agreeing 
  with 
  the 
  figure 
  of 
  Cory- 
  

   noides

  given 
  by

  has 
  been 
  

   found 
  to 
  replace 
  the 
  longer 
  form 
  in 
  the 
  Utica 
  beds 
  of 
  Panton 
  Vt., 
  the 
  

   Rural 
  cemetery 
  of 
  Albany 
  and 
  other 
  localities 
  in 
  the 
  Hudson 
  valley, 
  while 
  

   specimens 
  in 
  the 
  collection 
  of 
  the 
  New 
  York 
  state 
  museum 
  prove 
  its 
  pres- 
  

   ence 
  also 
  in 
  the 
  Utica 
  shale 
  of 
  Amsterdam. 
  One 
  slab 
  from 
  this 
  locality 
  is 
  

   so 
  densely 
  covered 
  with 
  these 
  graptolites 
  that 
  hardly 
  any 
  interspaces 
  are 
  

   left; 
  on 
  another 
  slab 
  from 
  the 
  same 
  locality 
  they 
  lie 
  associated 
  with 
  

   Diplograptus 
  putillus, 
  Lingula 
  curta 
  and

  One 
  slab 
  of 
  typical 
  black 
  Utica 
  shale 
  from 
  Sprak- 
  

   ers 
  Basin 
  shows 
  the 
  same 
  fossil. 
  It 
  is 
  a 
  remarkable 
  circumstance 
  that 
  

   the 
  writer 
  has 
  never 
  seen 
  a 
  single 
  specimen 
  in 
  the 
  Utica 
  shale 
  of 
  the 
  

   middle 
  or 
  upper 
  Mohawk 
  valley, 
  nor 
  are 
  there 
  any 
  specimens 
  in 
  the 
  rich 
  

   Rust 
  collection 
  of 
  the 
  state 
  museum 
  from 
  Holland 
  Patent. 
  This 
  may 
  

   indicate 
  a 
  regional 
  difference 
  in 
  the 
  fauna 
  of 
  the 
  Utica 
  shale. 
  The 
  com- 
  

   mon 
  occurrence 
  of 
  this 
  fossil 
  in 
  the 
  sandy 
  shales 
  of 
  Waterford, 
  whence 
  

   the 
  writer 
  has 
  it 
  in 
  the 
  same 
  slabs 
  with 
  Trinucleus 
  concen- 
  

   tricus 
  and 
  the 
  lamellibranchs 
  of 
  that 
  locality, 
  proves 
  that 
  it 
  even 
  

   ascends 
  into 
  the 
  Lorraine 
  beds. 
  One 
  specimen 
  has 
  been 
  found 
  at 
  Cal- 
  

   lanan's 
  quarry 
  near 
  South 
  Bethlehem 
  in 
  the 
  shale 
  of 
  that 
  formation 
  18 
  

   feet 
  below 
  the 
  waterlime 
  bed 
  of 
  the 
  Upper 
  Siluric. 
  

  

  The 
  writer 
  has 
  obtained 
  such 
  a 
  good 
  representation 
  of 
  this 
  still 
  very 
  im- 
  

   perfectly 
  understood 
  form 
  (Freeh 
  cites 
  it 
  among 
  the 
  doubtful 
  forms.

  that 
  its 
  more 
  important 
  morphologic 
  characters 
  can 
  be 
  made 
  out, 
  

   and 
  will 
  be 
  published 
  in 
  another 
  place.
