  Mr. 
  K.

  Blair— 
  /4 
  Bevision 
  of 
  

  

  no 
  gaps 
  of 
  any 
  size, 
  to 
  the 
  Cynodonts, 
  the 
  resemblance 
  of 
  

   whose 
  skull 
  to 
  that 
  of 
  a 
  mammal 
  is 
  so 
  close 
  as 
  to 
  render 
  the 
  

   determination 
  of 
  the 
  bones 
  quite 
  certain. 
  

  

  The 
  only 
  other 
  temporal 
  bone, 
  the 
  snpratemporal, 
  lies 
  

   between 
  the 
  squamosal, 
  parietal, 
  and 
  tabular. 
  This 
  is 
  the 
  

   position 
  held 
  by 
  the 
  upper 
  bone 
  in 
  all 
  Cotylosaurs 
  and 
  

   Stegocephalia 
  in 
  which 
  two 
  are 
  present. 
  

  

  It 
  is 
  thus 
  shown 
  by 
  direct 
  tracing 
  that 
  the 
  outer 
  temporal 
  

   element 
  — 
  that 
  which 
  in 
  Stegocephalia 
  lies 
  below 
  the 
  auditory 
  

   notch 
  and 
  passes 
  round 
  behind 
  the 
  quadrate 
  to 
  touch 
  the 
  

   pterygoid 
  — 
  is 
  the 
  mammalian 
  squamosal, 
  and 
  should 
  be 
  

   called 
  by 
  that 
  name. 
  

  

  In 
  conclusion, 
  I 
  wish 
  to 
  express 
  my 
  gratitude 
  to 
  Prof. 
  

   Broili, 
  not 
  only 
  for 
  so 
  kindly 
  allowing 
  me 
  to 
  describe 
  his 
  

   valuable 
  material, 
  but 
  also 
  for 
  his 
  many 
  personal 
  kindnesses 
  

   during 
  my 
  visits 
  to 
  Munich.

  A

  [Plate

  The 
  Pvrochroidse 
  may 
  be 
  shortly 
  characterized 
  as 
  Hetero- 
  

   mera 
  having 
  the 
  anterior 
  coxal 
  cavities 
  open 
  behind 
  ; 
  the 
  

   head, 
  which 
  is 
  held 
  horizontal, 
  consti'icted 
  into 
  a 
  neck 
  

   behind 
  ; 
  the 
  prothorax 
  at 
  base 
  markedly 
  narrower 
  than 
  the 
  

   base 
  of 
  the 
  elytra; 
  the 
  tarsal 
  claws 
  simple; 
  the 
  antennae, 
  at 
  

   anv 
  rate 
  in 
  the 
  male, 
  ramose 
  ; 
  and 
  the 
  eyes 
  large, 
  and 
  emar- 
  

   ginate 
  for 
  the 
  insertion 
  of 
  the 
  antennaj. 
  

  

  Lacordaiie, 
  in 
  Gen. 
  Col. 
  v. 
  1859, 
  only 
  recognized 
  three 
  

   „g„gra 
  — 
  Pyrochroa, 
  iSdiizotus, 
  and 
  Dendroides, 
  — 
  although 
  he 
  

   inclvxded 
  a 
  fourth, 
  Lemodes^ 
  with 
  an 
  expression 
  of 
  doubt 
  as 
  

   to 
  its 
  true 
  position. 
  The 
  genus 
  Pugonocerus, 
  Fisch., 
  he 
  

   considered 
  to 
  be 
  synonymous 
  with 
  Dendroides, 
  Latr. 
  

  

  Since 
  that 
  date 
  the 
  coristittition 
  of 
  the 
  family 
  has 
  remained 
  

   almost 
  unaltered 
  ; 
  a 
  few 
  new 
  genera 
  have 
  been 
  added 
  

   (Ischalia, 
  Base 
  =Eiipleurida, 
  Lee, 
  and 
  Pilipalpus, 
  Fairm.). 
  

   The 
  genus 
  Pedilus, 
  lisch., 
  has 
  by 
  some 
  authors 
  been 
  placed 
  

   here. 
  Though 
  there 
  is 
  much 
  to 
  be 
  said 
  in 
  favour 
  of 
  enlarging 
  

   the 
  scope 
  of 
  the 
  family 
  to 
  include 
  this 
  genus, 
  and 
  perhaps
