  Figure 
  3. 
  — 
  Cervical 
  vertebras 
  of 
  Stylinodon 
  rnirus, 
  with 
  first 
  dorsal 
  vertebra, 
  rib, 
  

   and 
  sternum, 
  in 
  position 
  ; 
  seen 
  from 
  the 
  left. 
  One-half 
  natural 
  size. 
  

   a, 
  atlas; 
  ax, 
  axis; 
  r, 
  rib; 
  s, 
  spine 
  of 
  first 
  dorsal 
  vertebra; 
  st, 
  

   sternum. 
  

  

  These 
  are 
  seen 
  to 
  good 
  advantage 
  in 
  figures 
  6 
  and 
  7, 
  where 
  the 
  

   bone 
  is 
  represented 
  one-half 
  natural 
  size. 
  These 
  figures 
  render 
  

   a 
  detailed 
  description 
  unnecessary. 
  This 
  bone, 
  like 
  all 
  those 
  

   of 
  the 
  skeleton, 
  is 
  solid, 
  there 
  being 
  no 
  medullary 
  cavity.
