  along 
  eacli 
  side 
  of 
  the 
  body 
  ; 
  a 
  more 
  or 
  less 
  distinct 
  

   round 
  gland 
  behind 
  the 
  angle 
  of 
  the 
  mouth. 
  Throat, 
  

   belly, 
  and 
  lower 
  surface 
  of 
  thighs, 
  or 
  belly 
  and 
  23ubic 
  

   region 
  granulate; 
  a 
  strong 
  gular 
  fold 
  separating 
  the 
  

   throat 
  from 
  the 
  breast. 
  

  

  Greyish 
  or 
  pale 
  brown 
  above, 
  speckled 
  with 
  darker 
  

   or 
  with 
  small 
  greyish-olive 
  or 
  greenish 
  spots, 
  some- 
  

   times 
  with 
  red 
  or 
  reddish 
  centres 
  ; 
  an 
  ill-defined 
  

   dark 
  canthal 
  streak 
  sometimes 
  present 
  ; 
  a 
  light 
  

   band 
  across 
  the 
  anterior 
  half 
  of 
  the 
  interocular 
  

   space, 
  and 
  a 
  triangular, 
  cordiform, 
  or 
  A-shaped 
  

   light 
  marking 
  between 
  the 
  shoulders 
  are 
  often 
  dis- 
  

   tinguishable, 
  and 
  between 
  these 
  two 
  light 
  markings 
  a 
  

   dark 
  triangle 
  or 
  X 
  ; 
  the 
  glands 
  of 
  the 
  lateral 
  series 
  

   often 
  orange 
  or 
  red. 
  Lower 
  parts 
  dirty 
  white 
  or 
  

   greyish, 
  with 
  the 
  granules 
  of 
  a 
  pure 
  Avhite; 
  limbs 
  

   carneous 
  ;

   especially

  sides. 
  Iris 
  pale 
  golden, 
  rarely 
  

   silvery, 
  veined

  Male 
  difficult 
  to 
  distinguish 
  from 
  the 
  female. 
  The 
  

   body 
  is, 
  however, 
  somewhat 
  shorter, 
  and 
  the 
  fore 
  

   limbs 
  are 
  a 
  little 
  stronger. 
  

  

  Geographical 
  Variations. 
  — 
  This 
  species 
  varies 
  very 
  

   little 
  in 
  France, 
  Germany, 
  and 
  Switzerland. 
  But 
  the 
  

   specimens 
  from 
  the 
  Spanish 
  Peninsula 
  show 
  less 
  

   uniformity 
  ; 
  the 
  more 
  divergent 
  may 
  be 
  distinguished 
  

   at 
  a 
  glance, 
  and 
  have 
  been 
  named 
  var. 
  hoscse, 
  

   Lataste. 
  The 
  skin 
  is 
  usually 
  smoother, 
  the 
  parotoid 
  

   glands 
  are 
  smaller, 
  and 
  the 
  dorsal 
  spots 
  are 
  generally 
  

   larger 
  and 
  better 
  defined, 
  sometimes 
  forming 
  mar- 
  

   blings 
  ; 
  these 
  characters 
  combine 
  to 
  produce 
  a 
  physi- 
  

   ognomy 
  somewhat 
  suggestive 
  of 
  a 
  young 
  Pelohates 
  

   cuUripes. 
  I 
  am, 
  however, 
  unable 
  to 
  confirm 
  the 
  abso- 
  

   lute 
  constancy 
  of 
  the 
  various 
  structural 
  differences 
  by 
  

   which 
  this 
  variety 
  is 
  to 
  be 
  distinguished 
  from 
  the 
  

   typical 
  form 
  ; 
  measurements 
  of 
  the 
  skull 
  and 
  vertebral 
  

   column 
  of 
  some 
  Rhenish 
  and 
  Spanish 
  specimens 
  show 
  

   me 
  that 
  the 
  proportions 
  may, 
  exceptionally, 
  be 
  the 
  

   same.
