  A 
  species 
  of 
  the 
  Dipterous 
  genus 
  Mydas, 
  representing 
  an 
  additional 
  family 
  

   (Mydaidae),»has 
  been 
  described 
  and 
  sent 
  for 
  publication. 
  

  

  The 
  plants 
  from 
  the 
  same 
  beds 
  cannot 
  at 
  present 
  be 
  listed 
  so 
  

   accurately 
  as 
  might 
  be 
  wished, 
  owing 
  to 
  some 
  outstanding 
  

   questions 
  of 
  generic 
  position, 
  synonymy 
  and 
  locality. 
  Using 
  

   my 
  best 
  judgment, 
  however, 
  I 
  find 
  that 
  the 
  apparently 
  valid 
  

   described 
  species 
  include 
  two 
  fungi, 
  two 
  mosses, 
  two 
  Characese, 
  

   one 
  Isoetacese, 
  five 
  Polypodiacese, 
  one 
  Schizaeacese, 
  seven 
  gym- 
  

   nosperms, 
  eleven 
  monocotyledonous 
  and 
  181 
  dicotyledonous 
  

   plants. 
  The 
  so-called 
  Tmesipteris 
  alleni 
  (Lx.) 
  Hollick, 
  

   although 
  common, 
  cannot 
  be 
  referred 
  to 
  any 
  genus 
  known 
  to 
  

   those 
  who 
  have 
  examined 
  it. 
  It 
  has 
  nothing 
  whatever 
  to 
  do 
  

   with 
  Tmesipteris, 
  nor 
  does 
  it 
  belong 
  to 
  Salvinia 
  or 
  Ophio- 
  

   glossum, 
  as 
  placed 
  by 
  Lesquereux. 
  It 
  may 
  be 
  known 
  for 
  the 
  

   present 
  as 
  Carpolithes 
  alleni
