  upward 
  ; 
  upper 
  secondaries 
  irregularly 
  disposed, 
  curving 
  upward 
  and 
  all 
  

   finally 
  thinning 
  out 
  close 
  to 
  the 
  margin 
  ; 
  tertiary 
  nervation 
  fine, 
  forming 
  a 
  

   series 
  of 
  loops 
  between 
  the 
  margin 
  and 
  the 
  outer 
  sides 
  of 
  the 
  lower

   daries. 
  

  

  This 
  beautiful 
  leaf 
  appears 
  to 
  be 
  entirely- 
  distinct 
  from 
  any 
  

   heretofore 
  described. 
  It 
  almost 
  certainly 
  belongs 
  in 
  the 
  Lau- 
  

   racecB 
  and 
  after 
  a 
  number 
  of 
  comparisons 
  with 
  living 
  species 
  in 
  

   the 
  genera 
  Phoebe, 
  O^-eodaphne, 
  Litscza, 
  etc. 
  I 
  have 
  decided 
  to 
  

   place 
  it 
  as 
  given 
  above.

  If 
  our 
  specimen 
  were 
  in 
  a 
  better 
  state 
  of 
  preservation 
  it 
  would 
  

   probably 
  not 
  be 
  necessary 
  to 
  question 
  the 
  reference 
  to 
  the 
  above 
  

   species, 
  of 
  which 
  it 
  seems 
  to 
  be 
  a 
  small 
  form. 
  I 
  have 
  thought 
  

   it 
  best 
  to 
  so 
  refer 
  it 
  however, 
  rather 
  than 
  to 
  attempt 
  a 
  descrip- 
  

   tion 
  of 
  a 
  new 
  species 
  founded 
  upon 
  fragmentary 
  material.

  I 
  have 
  included 
  our 
  specimens 
  under 
  this 
  protean 
  specie.^ 
  

   largely 
  for 
  the 
  reason 
  that 
  they 
  ma}^ 
  be 
  satisfactorily 
  compared 
  

   with 
  figures 
  of 
  specimens 
  referred 
  by 
  other 
  authors

  the
