  Skeleton 
  of 
  a 
  nearly 
  complete 
  Eocene 
  crocodile 
  and 
  a 
  partial 
  skele- 
  

   ton 
  of 
  Corythosaurus 
  , 
  a 
  crested 
  dinosaur 
  of 
  the 
  Upper 
  Cretaceous, 
  have 
  

   recently 
  been 
  added 
  to 
  the 
  exhibition 
  collection 
  of 
  fossil 
  vertebrates 
  in 
  

   the 
  United 
  States 
  National 
  Museum. 
  In 
  the 
  brief 
  notes 
  presented 
  

   here, 
  attention 
  is 
  called 
  to 
  some 
  of 
  the 
  more 
  interesting 
  anatomical 
  

   features 
  of 
  these 
  specimens, 
  and 
  measurements 
  arc 
  given 
  of 
  all 
  the 
  

   more 
  important 
  bones 
  in 
  order 
  to 
  make 
  these 
  data 
  available 
  to 
  stu- 
  

   dents 
  of 
  the 
  fossil 
  Reptilia. 
  The 
  crocodile 
  specimen 
  appears 
  to 
  be 
  

   unique 
  in 
  being 
  the 
  first 
  complete 
  skeleton 
  to 
  be 
  mounted 
  for 
  exhibi- 
  

   tion 
  in 
  this 
  country.
