  space 
  broad, 
  flat, 
  usually 
  as 
  broad 
  as 
  or 
  a 
  little 
  

   narrower 
  than 
  the 
  upper 
  eyelid, 
  sometimes, 
  however, 
  

   only 
  two-thirds 
  the 
  width 
  of 
  the 
  latter, 
  as 
  broad 
  as 
  

   or 
  a 
  little 
  narrower 
  than 
  the 
  distance 
  between 
  the 
  

   nostrils 
  ; 
  tympanum 
  very 
  distinct, 
  distant 
  from 
  the 
  

   eye,

  The 
  tibio-tarsal 
  articulation 
  reaches 
  the 
  tympanum, 
  

   the 
  eye, 
  or 
  the 
  nostril, 
  very 
  rarely 
  the 
  tip 
  of 
  the 
  snout 
  ; 
  

   tibia 
  shorter 
  than 
  the 
  fore 
  limb, 
  a 
  little 
  longer 
  than 
  

   the 
  femur, 
  as 
  long 
  as 
  or 
  a 
  little 
  shorter 
  than 
  the 
  foot 
  ; 
  

   the 
  heels 
  overlap 
  when 
  the 
  limbs 
  are 
  folded. 
  In 
  some 
  

   specimens 
  from 
  Spain 
  the 
  tibia 
  is 
  but 
  very 
  slightly 
  

   shorter 
  than

   fourth 
  toe, 
  however, 
  always 
  free 
  ; 
  toes 
  one-half 
  to 
  

   two-thirds 
  webbed 
  in 
  the 
  Spanish 
  var. 
  parvipalmata 
  ; 
  

   subarticular 
  tubercles 
  moderately 
  developed 
  ; 
  inner 
  

   metatarsal 
  tubercle 
  feeble, 
  soft, 
  roundish 
  or 
  oval, 
  

   measuring 
  less 
  than 
  one-half, 
  usually 
  about 
  one- 
  third, 
  

   the 
  length 
  of 
  the 
  inner 
  toe; 
  a 
  small 
  and 
  rather 
  indis- 
  

   tinct 
  tubercle 
  rarely 
  present 
  at 
  the 
  base 
  of 
  the 
  

   fourth 
  toe.

  dorso-lateral 
  folds 
  narrow 
  or
