  THE

  close 
  agreement 
  with 
  an 
  Araucarian 
  cone, 
  and 
  it 
  is 
  still 
  possible 
  that 
  

   it 
  may 
  represent 
  a 
  number 
  of 
  Araucarian 
  scales 
  detached 
  from 
  a 
  

   broad 
  central 
  axis 
  and 
  seen 
  from 
  the 
  inside. 
  The 
  distally-expanded 
  

   portions 
  of 
  the 
  scales 
  are 
  opposed 
  to 
  a 
  reference 
  to 
  an 
  Equisetaceous 
  

   strobilus. 
  On 
  the 
  whole, 
  the 
  specimen 
  is 
  probably 
  a 
  portion 
  of 
  some 
  

   Gymnospermous 
  cone, 
  either 
  Cycadean 
  or 
  Coniferous, 
  and 
  may 
  be 
  

   referred 
  provisionally 
  to 
  the 
  genus 
  Conites.

  (p.

  This 
  small 
  fragment 
  of 
  a 
  leaf 
  with 
  a 
  lobed 
  

   lamina 
  and 
  forked 
  lateral 
  veins 
  is 
  in 
  all 
  probability 
  a 
  piece 
  of 
  a 
  

   Sphenopteris-hond. 
  Zeiller 
  figures 
  a 
  fragment 
  from 
  the 
  same 
  

   locality 
  (Casey's 
  Township, 
  Frauds), 
  which 
  he 
  refers 
  to 
  this 
  genus, 
  

   but 
  probably 
  it 
  is 
  specifically 
  distinct 
  from 
  the 
  present 
  example. 
  

   The 
  piece 
  is 
  too 
  small 
  to 
  admit 
  of 
  specific 
  identification.

  (p. 
  324). 
  This 
  solitary 
  example 
  of 
  a 
  seed 
  among 
  the 
  

   fossils 
  sent 
  by 
  Mr. 
  Draper 
  was 
  found 
  on 
  splitting 
  open 
  a 
  small 
  piece 
  

   of 
  shale 
  from 
  Casey's 
  Township 
  (Francis). 
  It 
  measures 
  9 
  mm. 
  in 
  

   length, 
  and 
  6-5 
  mm. 
  in 
  breadth. 
  When 
  first 
  seen 
  there 
  was 
  a 
  loose 
  

   thin 
  lamina 
  of 
  coal 
  marking 
  the 
  position 
  of 
  the 
  seed, 
  occupying 
  

   the 
  slightly 
  depressed 
  area 
  faintly 
  indicated 
  in 
  the 
  drawing. 
  The 
  

   broad 
  carbonaceous 
  margin 
  surrounding 
  the 
  oval 
  central 
  region 
  

   is 
  interrupted 
  at 
  the 
  base 
  by 
  what 
  appears 
  to 
  be 
  a 
  canal 
  leading 
  

   to 
  the 
  base 
  of 
  the 
  seed. 
  Several 
  examples 
  of 
  fossil 
  seeds 
  from 
  

   Palaeozoic 
  rocks 
  have 
  been 
  figured 
  by 
  different 
  authors 
  which 
  show 
  

   a 
  close 
  resemblance 
  to 
  the 
  specimen 
  from 
  Francis. 
  Reference 
  

   may 
  be 
  made 
  to 
  Samaropsis 
  sp. 
  1 
  figured 
  by 
  Feistmantel 
  in 
  his 
  

   supplement 
  to 
  the 
  ' 
  Flora 
  of 
  the 
  Talchir-Karharbari 
  Beds 
  ;' 
  Cardio- 
  

   carpus 
  nervosa, 
  Kidst. 
  2 
  ; 
  Samaropsis 
  affinis, 
  Schk., 
  from 
  the 
  Coal 
  

   Measures

  China, 
  3 
  Samaropsis 
  Jluitans, 
  Weiss, 
  4 
  from 
  the 
  Upper 
  

   Ottweiler 
  Beds; 
  Cardiocarpus 
  simplex, 
  Lesq., 
  5 
  from 
  the 
  Carboniferous 
  

   of 
  North 
  America, 
  etc. 
  The 
  specimen 
  is 
  no 
  doubt 
  a 
  Grymnospermous 
  

   seed, 
  of 
  that 
  particular 
  type 
  placed 
  by 
  some 
  authors 
  in 
  the 
  genus 
  

   Samaropsis. 
  Schimper 
  includes 
  certain 
  seeds 
  of 
  this 
  form 
  under 
  

   Brongniart's 
  comprehensive 
  term 
  Cardiocarpus, 
  6 
  and 
  this 
  is 
  probably 
  

   the 
  wisest 
  course 
  to 
  adopt. 
  In 
  dealing 
  with 
  detached 
  portions 
  

   of 
  plants 
  such 
  as 
  seeds 
  or 
  cones, 
  it 
  is 
  better 
  to 
  use 
  compre- 
  

   hensive 
  generic 
  terms 
  rather 
  than 
  to 
  make 
  use 
  of 
  names 
  instituted
