  The 
  figures 
  in 
  paren- 
  

   theses 
  are 
  the 
  measurements 
  of 
  the 
  type. 
  

  

  The 
  type 
  is 
  a 
  young 
  animal, 
  the 
  molars 
  not 
  having 
  assumed 
  their 
  

   positions 
  in 
  the 
  jaws. 
  The 
  measurements 
  of 
  the 
  skull 
  as 
  will 
  be 
  seen, 
  

   are 
  considerably 
  exceeded 
  in 
  the 
  adult, 
  of 
  which 
  there 
  are 
  two 
  speci- 
  

   mens 
  in 
  the 
  British 
  Museum. 
  They 
  differ 
  from 
  the 
  young 
  in 
  color, 
  in 
  

   having 
  the 
  head 
  and 
  back 
  more 
  tawny, 
  the 
  yellow 
  markings 
  of 
  the 
  

   young 
  having 
  changed 
  to 
  tawny. 
  In 
  other 
  respects 
  they 
  are 
  alike, 
  with 
  

   no 
  yellow 
  beneath.
