  snout, 
  or 
  between 
  these 
  two 
  points. 
  Snout 
  usually 
  

   shorter 
  and 
  less 
  pointed 
  than 
  in 
  the 
  typical 
  form. 
  

   Skin 
  smooth 
  or 
  more 
  or 
  less 
  warty 
  ; 
  glandular 
  lateral 
  

   fold 
  more 
  or 
  less 
  prominent, 
  frequently 
  as 
  broad 
  as 
  

   the 
  upper 
  eyelid. 
  

  

  Specimens 
  from 
  the 
  south 
  of 
  France, 
  the 
  Spanish 
  

   Peninsula, 
  and 
  North 
  Africa, 
  vary 
  much 
  in 
  colour 
  — 
  

   olive, 
  dull 
  green, 
  bronzy-brown, 
  or 
  bright 
  green 
  above, 
  

   spotted 
  or 
  speckled 
  with 
  dark 
  olive 
  or 
  blackish, 
  with 
  

   or 
  without 
  a 
  light 
  vertebral 
  stripe 
  ; 
  the 
  hinder 
  side 
  

   of 
  the 
  thighs 
  whitish 
  or 
  pale 
  olive, 
  marbled 
  or 
  vermi- 
  

   culate 
  with 
  blackish 
  ; 
  belly 
  white, 
  uniform 
  or 
  with 
  

   small 
  blackish 
  spots. 
  

  

  German 
  specimens 
  are 
  less 
  variable. 
  In 
  the 
  normal 
  

   condition 
  the 
  ground 
  colour 
  of 
  the 
  upper 
  parts 
  is 
  olive 
  

   or 
  bronzy-olive, 
  with 
  the 
  vertebral 
  stripe, 
  the 
  fore 
  

   limbs, 
  and 
  the 
  sides 
  of 
  the 
  head 
  and 
  body 
  pale 
  green 
  

   or 
  pale 
  olive. 
  But 
  of 
  course, 
  through 
  the 
  play 
  of 
  the 
  

   chromatophores, 
  the 
  same 
  individual 
  may 
  pass 
  suc- 
  

   cessively 
  from 
  a 
  very 
  light 
  to 
  a 
  very 
  dark 
  hue, 
  ac- 
  

   cording 
  to 
  its 
  being 
  placed 
  in 
  very 
  dry 
  or 
  very 
  moist 
  

   surroundings. 
  In 
  specimens 
  long 
  kept 
  in 
  water 
  

   the 
  colour 
  turns 
  to 
  a 
  very 
  dark 
  bronze-olive, 
  almost 
  

   blackish, 
  in 
  which 
  case 
  the 
  normally 
  darker 
  markings 
  

   may 
  assume 
  a 
  brighter 
  greenish 
  tint 
  ; 
  but 
  if 
  these 
  mark- 
  

   ings 
  are 
  examined 
  with 
  a 
  magnifying 
  glass, 
  they 
  are 
  

   seen 
  to 
  be 
  black 
  beautifully 
  powdered 
  with 
  gold. 
  The 
  

   vertebral 
  stripe 
  varies 
  considerably 
  in 
  width, 
  and 
  may 
  

   be 
  absent 
  altogether. 
  The 
  glandular 
  lateral 
  folds 
  are 
  

   usually 
  not 
  conspicuously 
  lighter 
  coloured, 
  though 
  

   sometimes 
  metallic 
  bronzy. 
  The 
  spots 
  on 
  the 
  back 
  

   and 
  flanks 
  are 
  more 
  or 
  less 
  numerous, 
  but 
  these 
  

   markings 
  are 
  of 
  a 
  blackish-ohve 
  or 
  bronzy-brown, 
  and 
  

   never 
  of 
  an 
  intense 
  black 
  as 
  in 
  the 
  typical 
  form. 
  

   The 
  dorsal 
  spots 
  sometimes 
  form 
  prettyv 
  regular 
  longi- 
  

   tudinal 
  series, 
  but 
  are 
  never 
  confluent 
  into 
  longitudinal 
  

   bunds. 
  A 
  dark 
  canthal 
  and 
  supra-temporal 
  streak 
  is 
  

   usually 
  present, 
  and 
  sometimes 
  expands 
  into 
  a 
  regular 
  

   temporal 
  spot. 
  The 
  edge 
  of 
  the 
  upper 
  lip 
  is 
  either
