  articular 
  region 
  is 
  clearly 
  marked 
  off 
  from 
  the 
  rest 
  of 
  the 
  

   bone, 
  and 
  the 
  whole 
  glenoid 
  cavity 
  forms 
  a 
  screw-shaped 
  

   piece 
  of 
  the 
  surface 
  of 
  a 
  cylinder 
  whose 
  axis 
  stands 
  in 
  a 
  

   vertical 
  plane 
  pointing 
  downwards 
  towards 
  the 
  front 
  at 
  an 
  

   angle 
  of 
  about 
  60°.

  Varanosaurus 
  acutii-ostris, 
  Broili. 
  Type 
  specimen, 
  X 
  1. 
  

   Left 
  cartilao'inous 
  shoulder-ofirdle. 
  

  

  The 
  anterior 
  coracoidal 
  element 
  is 
  clearly 
  separated 
  from 
  

   the 
  scapular 
  by 
  a 
  suture, 
  which 
  has 
  parted, 
  allowing 
  tlie 
  

   bones 
  to 
  separate 
  by 
  a 
  little 
  less 
  than 
  a 
  millimetre. 
  The 
  

   anterior 
  coracoidal 
  element 
  has 
  a 
  process 
  which 
  joins 
  with 
  

   that 
  of 
  the 
  scapula 
  which 
  supports 
  the 
  anterior 
  end 
  of 
  the 
  

   glenoid 
  cavity. 
  

  

  Behind 
  this 
  process 
  is 
  a 
  deep 
  pocket, 
  from 
  which 
  the 
  

   coracoid 
  and 
  glenoid 
  foramina 
  must 
  start. 
  If 
  the 
  suture 
  

   between 
  this 
  bone 
  and 
  tlie 
  scapula 
  be 
  correctly 
  determined, 
  

   of 
  which 
  I 
  think 
  there 
  is 
  no 
  doubt, 
  the 
  bone 
  only 
  supports 
  

   an 
  extremely 
  small 
  piece 
  of 
  the 
  glenoid 
  cavity, 
  if 
  any 
  at 
  all. 
  

  

  The 
  posterior 
  coracoidal 
  element 
  is 
  a 
  small 
  bone 
  separated 
  

   from 
  the 
  scapula 
  by 
  an 
  obvious 
  suture 
  and 
  from 
  the 
  anterior 
  

   element 
  by 
  a 
  faint 
  and 
  incomplete 
  one. 
  

  

  That 
  the 
  bone 
  is 
  really 
  distinct 
  is 
  certain, 
  as 
  it 
  is 
  indicated 
  

   by 
  the 
  texture, 
  the 
  shape 
  of 
  the 
  internal 
  surface, 
  and 
  its 
  

   perfect 
  resemblance 
  to 
  Ophiacodoti. 
  The 
  bone 
  carries 
  a 
  large 
  

   part 
  of 
  the 
  glenoid 
  cavity, 
  and 
  has 
  a 
  low 
  process 
  on 
  its 
  

   posterior 
  edge.
