  Skeleton. 
  — 
  The 
  skull 
  is 
  less 
  strongly 
  ossified 
  than 
  

   in 
  Bafo 
  vulgaris; 
  the 
  fronto-parietals, 
  which 
  are 
  a 
  

   little 
  narrowed 
  in 
  front, 
  meet 
  only 
  in 
  the 
  posterior 
  

   half, 
  a 
  narrow 
  portion 
  of 
  the 
  endocranial 
  fontanelle 
  

   being 
  exposed 
  except 
  in 
  very 
  old 
  individuals 
  ; 
  these 
  

   bones 
  are 
  usually 
  separated 
  from 
  the 
  nasals, 
  a 
  part 
  

   of 
  the 
  upper 
  surface 
  of 
  the 
  ethmoid 
  remaining 
  exposed 
  

   in 
  front 
  of 
  them 
  ; 
  the 
  squamosal 
  is 
  more 
  detached 
  

   from 
  the 
  prootic.

  Upper 
  view 
  of 
  skull. 
  

  

  The 
  vertebral 
  column, 
  to 
  the 
  base 
  of 
  the 
  urostyle, 
  

   measures 
  once 
  and 
  one-fifth 
  to 
  once 
  and 
  one-third 
  the 
  

   length 
  of 
  the 
  skull 
  in 
  males, 
  once 
  and 
  a 
  half 
  to 
  once 
  

   and 
  three-fifths 
  in 
  females. 
  The 
  third 
  diapophysis 
  is 
  

   a 
  little 
  shorter 
  than 
  the 
  second; 
  the 
  sixth, 
  or 
  the 
  

   sixth 
  and 
  seventh, 
  are 
  directed 
  forwards. 
  The 
  distal 
  

   diameter 
  of 
  the 
  sacral 
  diapophysis 
  equals 
  its 
  length. 
  

   Urostyle 
  as 
  long 
  as 
  the 
  six 
  or 
  seven 
  vertebrae 
  preceding 
  

   it, 
  but 
  slightly 
  longer 
  than 
  the 
  skull, 
  exceptionally 
  

   with 
  a 
  short 
  transverse 
  process 
  at 
  the 
  base. 
  

  

  Two 
  bones 
  to 
  the 
  pollex, 
  which 
  is 
  much 
  more 
  de- 
  

   veloped 
  in 
  males 
  than 
  in 
  females. 
  Pelvis 
  as 
  long 
  as 
  

   the 
  vertebral 
  column 
  without 
  the 
  urostyle. 
  Tibia 
  as 
  

   long 
  as, 
  or 
  slightly 
  longer 
  than 
  the 
  femur, 
  which 
  is 
  

   more 
  strongly 
  curved 
  than 
  in 
  B. 
  vulgaris, 
  and 
  measures 
  

   once 
  and 
  two-thirds 
  to 
  once 
  and 
  four-fifths 
  the 
  length 
  

   of 
  the 
  tarsus. 
  

  

  Other 
  characters 
  as 
  in 
  B. 
  vulgaris.
