  Skeleton, 
  — 
  Skull 
  strongly 
  ossified. 
  Ethmoid 
  en- 
  

   tirely 
  or 
  nearly 
  entirely 
  covered 
  over 
  by 
  the 
  fronto- 
  

   parietals 
  and 
  the 
  large, 
  subtriangular 
  or 
  pear-shaped 
  

   nasals, 
  the 
  two 
  paired 
  bones 
  being 
  in 
  contact 
  with 
  

   each 
  other, 
  and 
  forming 
  a 
  continuous 
  or 
  subcontinuous 
  

   median 
  suture. 
  Squamosal 
  forming 
  a 
  suture 
  with 
  

   the 
  prootic, 
  its 
  zygomatic 
  process 
  very 
  short. 
  Of 
  the 
  

   three 
  branches 
  of 
  the 
  pterygoid, 
  the 
  anterior 
  is 
  the 
  

   longest 
  and 
  the 
  broadest, 
  and 
  joins 
  the 
  maxillary 
  and 
  

   the 
  palatine 
  ; 
  the 
  inner 
  branch 
  extends 
  to 
  the 
  para- 
  

   sphenoid, 
  w 
  r 
  hich 
  is 
  dagger-shaped, 
  obtuse 
  or 
  truncated 
  

   anteriorly, 
  and 
  in 
  contact 
  with 
  the 
  palatines. 
  Latter 
  

   bones 
  strong, 
  with 
  sharp 
  lower 
  keel. 
  Vomers 
  very 
  

   small, 
  widely 
  separated 
  from 
  each 
  other. 
  Mento- 
  

   Meckelian 
  bones 
  distinct. 
  

  

  Hyoid 
  much 
  longer 
  than 
  broad, 
  with 
  moderately 
  

   broad 
  cornua 
  without 
  anterior 
  processes, 
  small 
  alas, 
  

   short 
  posterolateral 
  processes, 
  and 
  slender, 
  diverging, 
  

   ossified 
  thyroid 
  processes, 
  which 
  are 
  narrowly 
  

   separated 
  from 
  each 
  other 
  at 
  the 
  base. 
  In 
  old 
  

   specimens 
  a 
  small 
  ossification 
  is 
  present 
  on 
  each 
  side 
  

   of 
  the 
  body 
  of 
  the 
  hyoid, 
  just 
  behind 
  the 
  level 
  of 
  the 
  

   anterior 
  notch. 
  

  

  Diapophyses 
  of 
  second 
  vertebra 
  much 
  flattened 
  and 
  

   directed 
  forwards 
  ; 
  of 
  third 
  vertebra 
  also 
  much 
  

   flattened, 
  longer, 
  and 
  horizontal; 
  of 
  fourth 
  a 
  little 
  

   longer 
  still, 
  less 
  flattened, 
  and 
  directed 
  backwards. 
  The 
  

   four 
  following 
  diapophyses 
  slender 
  and 
  subcylindrical, 
  

   gradually 
  decreasing 
  in 
  length 
  to 
  the 
  last 
  or 
  the 
  last 
  but 
  

   one, 
  the 
  first 
  two 
  directed 
  backwards, 
  the 
  other 
  two 
  

   horizontal. 
  Diapophyses 
  of 
  sacral 
  vertebra 
  dilated, 
  

   subtriangular, 
  their 
  distal 
  diameter 
  equal 
  to 
  or 
  a 
  

   little 
  less 
  than 
  their 
  length. 
  Two 
  condyles 
  for 
  articu- 
  

   lation 
  with 
  the 
  urostyle. 
  Latter 
  nearly 
  as 
  long 
  as 
  

   or 
  shorter 
  than 
  the 
  rest 
  of 
  the 
  vertebral 
  column, 
  a 
  

   little 
  longer 
  than 
  the 
  skull, 
  with 
  strong 
  dorsal 
  crest, 
  

   but 
  no 
  processes 
  at 
  the 
  base 
  save 
  exceptionally. 
  

  

  Prascoracoids 
  strong, 
  feebly 
  curved, 
  nearly 
  hori- 
  

   zontal, 
  entering 
  the 
  glenoid 
  cavity 
  ; 
  coracoids 
  slightly
