  sea. 
  This 
  plant-bed 
  therefore 
  would 
  seem 
  to 
  be 
  included 
  in 
  the 
  

   thickness 
  of 
  the 
  basalt. 
  A 
  number 
  of 
  specimens 
  were 
  collected 
  

   at 
  this 
  point 
  by 
  Dr. 
  Kcettlitz 
  and 
  subsequently 
  by 
  Dr. 
  Xansen. 
  

   The 
  last-named 
  gentleman 
  submitted 
  his 
  collection 
  to 
  Dr. 
  Nathorst, 
  

   the 
  well-known 
  Scandinavian 
  authority 
  on 
  fossil 
  plants, 
  and 
  a 
  very 
  

   interesting 
  account 
  of 
  them 
  'is 
  given 
  in 
  Dr. 
  Hansen's 
  'Farthest 
  

   North,' 
  l 
  together 
  with 
  some 
  woodcuts 
  of 
  certain 
  of 
  the 
  specimens. 
  

   According 
  to 
  Dr. 
  Nathorst 
  the 
  most 
  abundant 
  remains 
  were 
  needles 
  

   and 
  seeds 
  of 
  coniferous 
  plants, 
  which 
  he 
  refers 
  to 
  Pinns 
  and 
  Taxites 
  ; 
  

   but 
  the 
  most 
  interesting 
  among 
  his 
  specimens 
  are 
  leaves 
  of 
  the 
  

   genus 
  Ginkgo, 
  only 
  one 
  species 
  of 
  which 
  is 
  now 
  living, 
  in 
  Japan. 
  

   This 
  genus, 
  however, 
  is 
  very 
  characteristic 
  of 
  certain 
  Oolitic 
  deposits 
  

   in 
  Europe, 
  and 
  several 
  species 
  have 
  been 
  found 
  in 
  the 
  Jurassic, 
  Creta- 
  

   ceous, 
  and 
  Tertiary 
  strata 
  of 
  Spitsbergen, 
  Greenland, 
  and 
  Eastern 
  

   Siberia. 
  One 
  of 
  the 
  forms 
  from 
  Franz 
  Josef 
  Land 
  is 
  believed 
  by 
  

   Dr. 
  Nathorst 
  to 
  be 
  a 
  new 
  species, 
  for 
  which 
  he 
  proposes 
  the 
  name 
  

   of 
  Ginkgo 
  polar 
  is. 
  It 
  is 
  said 
  to 
  be 
  a 
  near 
  ally 
  of 
  G. 
  fabellata 
  from 
  

   the 
  Jurassic 
  of 
  Siberia, 
  and 
  is 
  not 
  unlike 
  the 
  G. 
  digitata 
  from 
  

   British 
  Oolitic 
  strata. 
  

  

  A 
  few 
  ferns 
  were 
  included 
  in 
  Dr. 
  Hansen's 
  collection, 
  and 
  these 
  

   are 
  said 
  to 
  represent 
  four 
  types, 
  but 
  to 
  be 
  too 
  imperfect 
  for 
  specific 
  

   determination. 
  One 
  of 
  these 
  is 
  referred 
  to 
  the 
  genus 
  Gladoplilebix 
  ; 
  

   two 
  others 
  are 
  said 
  to 
  suggest 
  the 
  genera 
  Thyrsopteris 
  and 
  Ony- 
  

   (Jiiopsis, 
  while 
  the 
  fourth 
  seems 
  closely 
  allied 
  to 
  the 
  Asplenium 
  

   petruschinense 
  described 
  by 
  Heer 
  from 
  Jurassic 
  strata 
  in 
  Siberia.

  A 
  goodly 
  number 
  of 
  examples 
  of 
  these 
  plant-impressions 
  collected 
  

   by 
  Dr. 
  Kcettlitz 
  have 
  been 
  sent 
  home, 
  and 
  although 
  small 
  and 
  

   fragmentary, 
  as 
  indeed 
  were 
  all 
  the 
  specimens 
  found 
  at 
  this 
  locality, 
  

   they 
  represent 
  most 
  of 
  the 
  forms 
  mentioned 
  by 
  Dr. 
  Nathorst. 
  

   There 
  are 
  many 
  of 
  the 
  winged 
  seeds 
  of 
  Pinus, 
  varying 
  in 
  form, 
  and 
  

   possibly 
  representing 
  more 
  than 
  one 
  of 
  the 
  species 
  alluded 
  to 
  in 
  the 
  

   above 
  list 
  (PI. 
  XXXYIII, 
  figs. 
  6-8). 
  With 
  these 
  are 
  numerous 
  

   pine-needles, 
  both 
  broad 
  and 
  narrow, 
  as 
  well 
  as 
  a 
  portion 
  of 
  a 
  branch 
  

   and 
  a 
  small 
  cone. 
  A 
  few 
  fragments 
  may 
  belong 
  to 
  the 
  genus 
  

   Fieldenia 
  [Torellia] 
  (PI. 
  XXXYIII, 
  fig. 
  11). 
  The 
  peculiar 
  form 
  

   Ginkgo 
  is 
  represented 
  by 
  many 
  specimens,

  of 
  which
