  uniform 
  black, 
  or 
  grey 
  spotted 
  with 
  blaok. 
  In 
  

   these 
  peninsular 
  specimens, 
  which 
  strongly 
  contrast 
  

   with 
  those 
  from 
  north 
  of 
  the 
  Po, 
  the 
  yellow 
  of 
  the 
  

   under 
  surface 
  of 
  the 
  arm 
  does 
  not 
  extend 
  across 
  the 
  

   breast 
  as 
  usual 
  in 
  the 
  individuals 
  from 
  North 
  Italy, 
  

   Austria-Hungary, 
  and 
  Germany 
  (var. 
  hrevipes), 
  and 
  

   as 
  shown 
  by 
  the 
  example 
  from 
  Schemnitz, 
  Hungary, 
  

   figured 
  on 
  PI. 
  YI, 
  fig. 
  5; 
  but 
  the 
  breast 
  is 
  either 
  

   uniform 
  blue, 
  grey, 
  or 
  blackish, 
  or 
  bears 
  a 
  pair 
  of 
  

   isolated 
  spots 
  as 
  in 
  B. 
  igneus. 
  In 
  France, 
  Belgium, 
  

   and 
  Switzerland 
  we 
  find 
  individuals 
  bridging 
  over 
  the 
  

   two 
  forms. 
  Specimens, 
  eight 
  in 
  number, 
  obtained 
  by 
  

   M. 
  Lataste 
  at 
  Boulay-les-Trous, 
  near 
  Paris, 
  are 
  very 
  

   interesting 
  in 
  this 
  respect. 
  In 
  all 
  the 
  plantar 
  spot 
  is 
  

   completely 
  separated 
  from 
  the 
  tarsal, 
  which 
  may 
  be 
  

   large 
  or 
  broken 
  up 
  and 
  reduced 
  to 
  a 
  few 
  marblings 
  ; 
  

   in 
  some 
  the 
  spots 
  on 
  the 
  breast 
  are 
  completely 
  

   detached 
  from 
  those 
  of 
  the 
  fore 
  limbs, 
  and 
  the 
  inner 
  

   digits 
  of 
  both 
  hand 
  and 
  foot 
  are 
  not 
  completely 
  

   involved 
  in 
  the 
  palmar 
  or 
  plantar 
  spot. 
  Detached 
  

   spots 
  on 
  the 
  breast 
  and 
  tarsus 
  also 
  occur 
  in 
  Belgian 
  

   examples. 
  In 
  25 
  from 
  near 
  Dinant 
  I 
  count 
  16 
  with 
  

   the 
  plantar 
  spot 
  separated 
  from 
  the 
  tarsal 
  on 
  both 
  

   sides, 
  3 
  with 
  the 
  two 
  confluent, 
  and 
  6 
  in 
  which 
  the 
  

   right 
  side 
  belongs 
  to 
  the 
  one, 
  and 
  the 
  left 
  to 
  the 
  other 
  

   of 
  the 
  two 
  categories. 
  In 
  25 
  from 
  Mondorf, 
  Luxem- 
  

   burg, 
  7 
  belong 
  to 
  the 
  first 
  category, 
  12 
  to 
  the 
  second, 
  

   and 
  6 
  to 
  either. 
  A 
  specimen 
  from 
  Goslar, 
  Harz, 
  has 
  

   also 
  the 
  plantar 
  and 
  tarsal 
  spots 
  disconnected. 
  

  

  Some 
  of 
  the 
  principal 
  variations 
  observed 
  in 
  the 
  

   markings 
  of 
  the 
  lower 
  parts 
  are 
  represented 
  on 
  PI. 
  YI. 
  

  

  Iris 
  more 
  uniformly 
  bronzy 
  than 
  in 
  the 
  preceding 
  

   species, 
  with 
  the 
  golden 
  edge 
  to 
  the 
  pupil 
  finer, 
  less 
  

   distinct 
  ; 
  pupil 
  roundish, 
  with 
  lower 
  angle 
  triangular, 
  

   or, 
  more 
  frequently, 
  cordiform, 
  Y-shaped 
  when 
  fully 
  

   contracted. 
  

  

  Yery 
  young 
  specimens 
  bluish-white 
  or

  with 
  black 
  spots 
  and 
  large 
  yellow 
  blotches 
  

   on 
  the 
  limbs 
  {Biifo
