  work 
  includes 
  the 
  flora 
  of 
  the 
  Epinac 
  and 
  Molloy 
  stages 
  of 
  the 
  

   Upper 
  Carboniferous 
  and 
  the 
  Igornay-Lally, 
  Cornaille-Chambois, 
  

   and 
  Millery 
  stages 
  of 
  the 
  Lower 
  Permian. 
  The 
  Millery 
  horizon, 
  

   in 
  the 
  Autun 
  basin, 
  is 
  celebrated 
  as 
  the 
  source 
  of 
  the 
  wonderfully 
  

   preserved 
  silicified 
  plants 
  that 
  formed 
  the 
  basis 
  of 
  the 
  many 
  

   important 
  works 
  on 
  the 
  organization 
  and 
  fructification 
  of 
  the 
  

   plants 
  of 
  the 
  Paleozoic 
  by 
  Brongniart, 
  Grand 
  'Eury, 
  Renault, 
  

   Bertrand, 
  and 
  Zeiller. 
  In 
  this 
  fascicle 
  Zeiller 
  treats 
  the 
  ferns, 
  

   prefacing 
  their 
  description 
  with 
  an 
  illustrated 
  resume 
  of 
  the 
  

   classification 
  of 
  the 
  types 
  represented 
  in 
  this 
  flora 
  according 
  to 
  

   their 
  discovered 
  fruiting 
  forms. 
  Considerable 
  new 
  and 
  interest- 
  

   ing 
  material 
  is 
  here 
  brought 
  to 
  light. 
  About 
  forty 
  species, 
  many 
  

   of 
  them 
  new, 
  are 
  described 
  from 
  foliar 
  and 
  fruiting 
  characters. 
  

   The 
  last 
  120 
  pages 
  contain 
  descriptions 
  and 
  illustrations 
  of 
  the 
  

   trunks 
  and 
  petioles 
  of 
  the 
  ferns, 
  belonging 
  to 
  Ptychopteris, 
  in- 
  

   cluding 
  Caulopteris 
  gigantea, 
  F. 
  & 
  W., 
  to 
  Psaronius, 
  represent- 
  

   ing 
  trunks 
  of 
  Pecopteris 
  and 
  Scolecopteris, 
  and 
  comprising 
  an 
  

   extinct 
  tribe 
  of 
  the 
  31arattiacece, 
  and 
  to 
  Myeloxylon, 
  including 
  

   Medullosa 
  (pars), 
  Myelopteris 
  and 
  Stenzelia, 
  which 
  he 
  regards 
  

   as 
  petioles 
  and 
  rachises 
  of 
  Alethopteris. 
  Odontopteris 
  and 
  Neur- 
  

   opteris, 
  representing 
  a 
  group, 
  with 
  pithed 
  petioles 
  and 
  a 
  cen- 
  

   trifugally 
  developed 
  secondary 
  woody 
  zone, 
  perhaps 
  intermediate 
  

   between 
  the 
  Ophioglossacece 
  and 
  the 
  Marattiacece. 
  The 
  flora 
  is 
  

   interesting 
  as 
  showing 
  many 
  transition 
  forms 
  between 
  the 
  Upper 
  

   Carboniferous 
  and 
  the 
  Permian 
  types. 
  The 
  second

   — 
  In 
  this 
  short 
  paper 
  Dr. 
  Newberry 
  reiterates 
  the 
  view 
  pro- 
  

   posed 
  first 
  b}^ 
  himself 
  in 
  1853, 
  and 
  afterwards 
  independently 
  

   by 
  Coemans 
  and 
  Kickx, 
  that 
  in 
  certain 
  species 
  of 
  Sp>henophyllum 
  

   in 
  which 
  the 
  leaves 
  are 
  normally 
  wedge-shaped 
  and 
  dentate 
  or 
  

   serrate, 
  the 
  deeply 
  dissected, 
  fimbriate, 
  or 
  capillary 
  forms, 
  simu- 
  

   lating 
  Asterophyllites, 
  belonging 
  to 
  the 
  same 
  species, 
  represent 
  

   only 
  portions 
  of 
  the 
  same 
  plant 
  that 
  were 
  submerged. 
  Several 
  

   figures 
  illustrate 
  different 
  parts 
  of 
  8. 
  erosum, 
  including 
  the 
  forms 
  

   known 
  as 
  S. 
  saxifragcefolium. 
  The 
  author 
  also 
  gives 
  a 
  few 
  of 
  

   the 
  characters 
  of 
  six 
  species 
  of 
  this 
  genus 
  with 
  which 
  he 
  is 
  

   familiar 
  in 
  this 
  country. 
  Dr. 
  Newberry 
  regards 
  Sphenophylhwi, 
  

   whose 
  affinities 
  have 
  for 
  over 
  fifty 
  years 
  been 
  the 
  subject 
  of 
  

   controversial 
  discussions, 
  as 
  representing 
  a 
  peculiar 
  and 
  extinct 
  

   family 
  whose 
  nearest 
  living 
  relative 
  is 
  JEquisetiun.
