  NEWTON 
  AND 
  J.

  H. 
  TEALL 
  ON 
  [Dec. 
  1897, 
  

  

  collected 
  a 
  number 
  of 
  fragmentary 
  fossils 
  which 
  had 
  been 
  washed 
  out 
  

   from 
  the 
  rock. 
  These 
  fossils 
  are 
  mostly 
  either 
  pieces 
  of 
  belemnites 
  

   or 
  parts 
  of 
  a 
  large 
  species 
  of 
  Avicula, 
  but 
  there 
  is 
  one 
  fragment 
  of 
  an 
  

   ammonite 
  allied 
  to 
  A. 
  Goiverianus, 
  which 
  is 
  as 
  yet 
  undetermined. 
  

  

  Belemnites 
  sp. 
  

  

  Most 
  of 
  the 
  fragments 
  of 
  belemnites 
  from 
  this 
  locality 
  are 
  so 
  

   much 
  broken 
  and 
  decomposed 
  that 
  it 
  is 
  hopeless 
  to 
  think 
  of 
  specific 
  

   determination, 
  nevertheless 
  there 
  are 
  a 
  few 
  points 
  which 
  may 
  be 
  

   noticed. 
  There 
  are 
  evidently 
  two 
  if 
  not 
  three 
  forms, 
  but 
  none 
  of 
  

   them 
  can 
  be 
  referred 
  to 
  B. 
  Panderi, 
  as 
  they 
  do 
  not 
  show 
  the 
  

   marked 
  excentric 
  radiation 
  of 
  the 
  transverse 
  section 
  characteristic 
  

   of 
  that 
  species. 
  One 
  form 
  is 
  compressed, 
  with 
  a 
  well-marked 
  

   groove 
  near 
  the 
  apex 
  and 
  a 
  slightly 
  excentric 
  radiation. 
  

  

  A 
  second 
  form 
  is 
  similar, 
  but 
  much 
  more 
  compressed, 
  and 
  there 
  

   seems 
  to 
  have 
  been 
  a 
  deep 
  groove 
  extending 
  from 
  the 
  apex 
  some 
  

   distance 
  up 
  the 
  guard. 
  

  

  The 
  third 
  form 
  is 
  cylindrical, 
  concentrically 
  radiated, 
  and 
  with 
  a 
  

   comparatively 
  acute 
  apex. 
  

  

  Some 
  of 
  these 
  belemnites 
  may 
  be 
  the 
  same 
  as 
  those 
  from 
  

   locality 
  4. 
  

  

  Avicula 
  sp. 
  cf. 
  injeqtjivalvis. 
  (PL 
  XL, 
  fig. 
  4.) 
  

  

  There 
  are 
  several 
  of 
  these 
  large 
  aviculas, 
  but 
  all 
  are 
  more 
  or 
  less 
  

   crushed 
  and 
  broken 
  ; 
  some 
  of 
  them, 
  probably 
  on 
  account 
  of 
  break- 
  

   age, 
  look 
  more 
  equilateral 
  than 
  others, 
  and 
  at 
  first 
  sight 
  remind 
  

   one 
  of 
  Pecten 
  ; 
  but 
  the 
  large 
  wing 
  on 
  one 
  side 
  shows 
  that 
  they 
  do 
  

   not 
  belong 
  to 
  that 
  genus. 
  

  

  The 
  best-preserved 
  specimen 
  (fig. 
  4) 
  in 
  its 
  present 
  condition 
  is 
  

   1| 
  inch 
  in 
  length; 
  but, 
  with 
  the 
  exception 
  of 
  the 
  umbo 
  and 
  a 
  

   piece 
  of 
  the 
  hinge, 
  all 
  the 
  margins 
  are 
  broken 
  away, 
  and, 
  judging 
  

   from 
  other 
  fragments, 
  the 
  species 
  must 
  have 
  reached 
  3 
  or 
  4 
  

   inches 
  in 
  diameter. 
  One 
  valve 
  is 
  moderately 
  convex, 
  while 
  the 
  

   opposite 
  valve 
  is 
  concave. 
  Strong 
  ribs 
  radiate 
  from 
  the 
  umbo 
  to 
  

   the 
  margin 
  ; 
  between 
  these 
  are 
  finer 
  ribs, 
  and 
  a 
  third 
  still 
  smaller 
  

   series 
  are 
  to 
  be 
  seen 
  between 
  each 
  of 
  these, 
  giving 
  the 
  shell 
  much 
  

   the 
  appearance 
  of 
  a 
  well-marked 
  A. 
  incequivalvis, 
  but 
  in 
  that 
  species 
  

   the 
  ribs 
  are 
  not 
  nearly 
  so 
  strong. 
  The 
  concave 
  valve 
  is 
  less 
  

   distinctly 
  marked 
  than 
  the 
  other. 
  The 
  hinge 
  is 
  long, 
  and 
  the 
  

   posterior 
  wing 
  is 
  much 
  larger 
  than 
  the 
  anterior. 
  Some 
  of 
  the 
  

   specimens 
  appear 
  to 
  be 
  more 
  equilateral 
  than 
  others, 
  but 
  this 
  is 
  

   believed 
  to 
  be 
  due 
  to 
  crushing, 
  and 
  as 
  all 
  have 
  similar 
  markings 
  

   they 
  are 
  regarded 
  as 
  one 
  species. 
  

  

  The 
  small 
  height 
  above 
  the 
  sea 
  at 
  which 
  this 
  exposure 
  of 
  rock 
  is- 
  

   situated, 
  to 
  the 
  west 
  of 
  Elmwood, 
  shows 
  that 
  it 
  occupies 
  a 
  position 
  at 
  

   about 
  250 
  feet 
  below 
  the 
  bed 
  with 
  Ammonites 
  Ishmce 
  var. 
  arcticus 
  

   at 
  Windy 
  Gully, 
  but 
  the 
  specimens 
  give 
  no 
  idea 
  of 
  their 
  age.
