  Skeleton. 
  — 
  Apart 
  from 
  the 
  stouter 
  and 
  shorter 
  

   limb-bones, 
  the 
  skeleton 
  of 
  this 
  species 
  differs 
  from 
  

   that 
  of 
  the 
  preceding 
  in 
  the 
  larger 
  nasals, 
  which 
  over- 
  

   lap 
  the 
  ethmoid 
  and 
  the 
  inner 
  borders 
  of 
  which 
  meet 
  

   along 
  their 
  entire 
  length, 
  in 
  the 
  constricted 
  fronto- 
  

   parietals, 
  and 
  in 
  the 
  shape 
  of 
  the 
  fron 
  to-parietal 
  

   fontanelle, 
  which 
  is 
  divided 
  into 
  two 
  portions 
  between 
  

   which 
  the 
  fronto-parietals 
  form 
  a 
  bridge 
  ; 
  the 
  anterior 
  

   fontanelle 
  is 
  large 
  and 
  kite-shaped, 
  the 
  posterior 
  very 
  

   small, 
  a 
  mere 
  foramen 
  between 
  the 
  fronto-parietals.

  The 
  coracoids 
  and 
  prsecoracoids 
  are 
  more 
  flattened 
  

   and 
  more 
  robust, 
  and 
  the 
  metacarpal 
  and 
  phalanges 
  

   of 
  the 
  outer 
  finger 
  are 
  shorter 
  and 
  more 
  massive 
  ; 
  the 
  

   terminal 
  one 
  in 
  particular 
  being 
  extremely 
  short, 
  

   nearly 
  hemispherical. 
  The 
  femur 
  is 
  slightly 
  longer 
  

   than 
  the 
  tibia.

  more 
  strongly 
  ossified
