  Skeleton. 
  — 
  Skull 
  very 
  strongly 
  ossified, 
  the 
  maxil- 
  

   laries, 
  squamosals, 
  nasals, 
  ethmoid, 
  and 
  fronto-parietal 
  

   rugose, 
  granular, 
  or 
  pitted. 
  Ethmoid 
  entirely 
  ossified, 
  

   confluent 
  with 
  the 
  likewise 
  ossified 
  nasal 
  capsule, 
  and 
  

   produced 
  forwards 
  beyond 
  the 
  nasals 
  to 
  between 
  the 
  

   ascending 
  processes 
  of 
  the 
  prsemaxillaries 
  ; 
  only 
  a 
  

   small 
  triangular 
  portion 
  of 
  it 
  is 
  exposed 
  between 
  the 
  

   nasals 
  and 
  the 
  fronto-parietal. 
  Nasals 
  large, 
  in 
  con- 
  

   tact 
  with 
  each 
  other 
  between 
  the 
  nares. 
  Fronto- 
  

   parietal 
  single, 
  widening 
  behind 
  into 
  a 
  more 
  or 
  less 
  

   developed 
  angular 
  process 
  on 
  each 
  side 
  ; 
  this 
  process 
  

   is 
  more 
  or 
  less 
  widely 
  separated 
  from 
  a 
  corresponding 
  

   one 
  of 
  the 
  squamosal, 
  with 
  which 
  it 
  is 
  connected 
  by 
  

   ligament 
  only, 
  the 
  prootic 
  being 
  entirely 
  exposed 
  

   above. 
  Transverse 
  branch 
  of 
  squamosal 
  expanded, 
  

   plate-like, 
  suturally 
  united 
  in 
  front 
  with 
  the 
  maxillary. 
  

  

  The 
  degree 
  of 
  roughness 
  of 
  the 
  fronto-parietals 
  and 
  

   the 
  development 
  of 
  the 
  post-orbital 
  processes 
  vary 
  

   according 
  to 
  individuals, 
  the 
  bone 
  being 
  generally 
  less 
  

   developed 
  in 
  this 
  respect 
  in 
  specimens 
  from 
  France 
  

   than 
  in 
  those 
  from 
  Germany, 
  Austria, 
  and 
  Italy. 
  In 
  

   quite 
  young 
  specimens 
  the 
  fronto-parietal 
  is 
  nearly
