  not 
  reacbing 
  the 
  vomers, 
  leaving 
  the 
  ethmoid 
  un- 
  

   covered, 
  or 
  covering 
  but 
  a 
  small 
  portion 
  of 
  it. 
  Stapes 
  

   absent. 
  No 
  well-defined 
  mento-Meckelian 
  bones. 
  

  

  Hyoid 
  a 
  large 
  broad 
  plate 
  with 
  two 
  pairs 
  of 
  ossifica- 
  

   tions 
  ; 
  ceratohyal 
  cornua 
  broad 
  and 
  without 
  forward 
  

   processes; 
  postero-lateral 
  process 
  large, 
  ossified 
  at 
  the 
  

   base, 
  this 
  ossification 
  extending 
  to 
  the 
  body 
  of 
  the 
  

   hyoid 
  and 
  sometimes 
  nearly 
  meeting 
  its 
  fellow 
  in 
  front 
  

   of 
  the 
  likewise 
  ossified 
  but 
  slender 
  thyrohyals. 
  

  

  Vertebral 
  column 
  twice 
  and 
  one-third 
  to 
  twice 
  and 
  

   a 
  half 
  as 
  long 
  as 
  the 
  skull. 
  Yertebrse 
  imbricate, 
  the 
  

   column 
  closed 
  above. 
  Second, 
  third, 
  and 
  fourth 
  ver- 
  

   tebrae 
  with 
  short 
  diapophyses 
  and 
  small 
  distinct 
  ribs, 
  

   the 
  second 
  of 
  which 
  is 
  the 
  longest, 
  and 
  bears 
  a 
  small 
  

   posterior 
  process 
  as 
  in 
  Discoglossus. 
  The 
  first 
  diapo- 
  

   physis 
  is 
  directed 
  forwards, 
  the 
  second, 
  third, 
  and 
  

   fourth 
  are 
  nearly 
  horizontal, 
  and 
  the 
  three 
  following 
  

   are 
  again 
  directed 
  forwards. 
  The 
  diapophysis 
  of 
  the 
  

   sacral 
  vertebra 
  are 
  very 
  strongly 
  dilated, 
  and 
  cover 
  

   the 
  anterior 
  third 
  of 
  the 
  pelvis 
  ; 
  their 
  longitudinal 
  

   diameter, 
  without 
  the 
  cartilaginous 
  epiphysis, 
  equals 
  

   about 
  twice 
  the 
  transverse 
  diameter 
  ; 
  this 
  vertebra 
  

   has 
  a 
  single 
  condyle 
  for 
  articulation 
  with 
  the 
  urostyle. 
  

   As 
  in 
  Discoglossus, 
  the 
  latter 
  bone 
  has 
  a 
  posteriorly 
  

   directed, 
  slender 
  transverse 
  process 
  on 
  each 
  side 
  at 
  

   its 
  base, 
  but 
  usually 
  more 
  developed, 
  its 
  length 
  often 
  

   exceeding 
  that 
  of 
  any 
  of 
  the 
  processes 
  of 
  the 
  prsesacral 
  

   region 
  ; 
  it 
  is 
  sometimes 
  followed 
  by 
  a 
  second 
  similar 
  

   process 
  ; 
  the 
  length 
  of 
  the 
  urostyle 
  equals 
  that 
  of 
  

   the 
  skull, 
  or 
  of 
  the 
  six 
  or 
  seven 
  anterior 
  vertebrsB. 
  

  

  Praecoracoids 
  moderately 
  slender, 
  strongly 
  curved, 
  

   entering 
  the 
  glenoid 
  cavity 
  ; 
  coracoids 
  little 
  stronger, 
  

   feebly 
  curved 
  ; 
  supra-scapula 
  cartilaginous, 
  or 
  partially 
  

   ossified 
  ; 
  sternum 
  cartilaginous, 
  produced 
  into 
  two 
  

   long, 
  slender, 
  diverging 
  processes. 
  Humerus 
  once 
  

   and 
  one-third 
  as 
  long 
  as 
  radius-ulna. 
  Carpus 
  with 
  

   eight 
  elements, 
  as 
  in 
  Discoglossus, 
  two 
  of 
  which 
  are 
  

   in 
  contact 
  with 
  radius-ulna; 
  two 
  bones 
  in 
  the 
  pollex. 
  

  

  Pelvis 
  measuring 
  three-fifths 
  to 
  two-thirds 
  the
