  nothing

  New 
  synonymy. 
  

  

  This 
  and 
  the 
  next 
  genus 
  form 
  a 
  distinct 
  group 
  characterized 
  espe- 
  

   cially 
  by 
  the 
  entire 
  lack 
  of 
  the 
  occipital 
  carina; 
  very 
  smxail 
  mandible 
  

   with 
  the 
  upper 
  tooth 
  shifted 
  to 
  the 
  inner 
  margin, 
  so 
  that 
  when 
  closed 
  

   the 
  mandible 
  appears 
  edentate; 
  a 
  longitudinal 
  groove 
  dividing 
  the 
  

   mesopleuron 
  into 
  nearly 
  equal 
  upper 
  and 
  lower 
  parts; 
  extremely 
  

   narrow, 
  attenuate 
  stigma 
  with 
  radius 
  near 
  base, 
  basally 
  thickened 
  

   and 
  strongly 
  curved 
  radius; 
  and 
  the 
  presence 
  on 
  the 
  outer 
  apical 
  

   margin 
  of 
  the 
  trochanter 
  in 
  middle 
  and 
  hind 
  legs 
  of 
  a 
  sharp 
  decurved 
  

   tooth. 
  Of 
  these, 
  the 
  peculiarly 
  formed 
  mandible 
  and 
  the 
  trochan- 
  

   teral 
  tooth 
  occur 
  only 
  in 
  these 
  two 
  genera 
  and 
  in 
  no 
  other 
  genus 
  do 
  

   the 
  other 
  characters 
  listed 
  occur 
  in 
  the 
  same 
  combination. 
  

  

  Neither 
  Szephgeti 
  nor 
  Morley 
  nor 
  Uchida 
  understood 
  this 
  genus, 
  

   for 
  Sz^pligeti 
  synonymized 
  it 
  with 
  Eremotylus 
  Foerster, 
  Morley 
  

   synonymized 
  with 
  it 
  Spilophion 
  Cameron, 
  and 
  Uchida 
  accepted 
  

   Morley's 
  interpretation 
  while 
  redescribing 
  it 
  as 
  Nipponophion. 
  

   Both 
  Eremotylus 
  and 
  Spilophion 
  have 
  the 
  occipital 
  carina 
  distinct, 
  

   whereas 
  the 
  lack 
  of 
  this 
  carina 
  is 
  one 
  of 
  the 
  most 
  anomalous 
  characters 
  

   of 
  Stauropoctonus. 
  

  

  Head 
  (pi. 
  50, 
  fig. 
  15): 
  Unusually 
  small; 
  temples 
  somewhat 
  convex 
  

   but 
  narrow 
  and 
  sharply 
  receding; 
  occipital 
  carina 
  entirely 
  absent, 
  

   postvertex 
  descending 
  perpendicularly 
  from 
  ocelli, 
  which 
  are 
  very 
  

   large 
  and 
  contiguous 
  with 
  eyes; 
  eyes 
  large, 
  bulging, 
  deeply 
  emarginate,
