  As 
  may 
  be 
  seen 
  from 
  the 
  preceding 
  table 
  of 
  measure- 
  

   ments, 
  this 
  form 
  reaches 
  to 
  a 
  very 
  large 
  size, 
  much 
  

   exceeding 
  that 
  of 
  the 
  two 
  others. 
  

  

  Forma 
  typica. 
  

  

  Inner 
  metatarsal 
  tubercle 
  strong, 
  compressed, 
  pro- 
  

   minent, 
  its 
  length 
  2 
  to 
  3 
  times 
  in 
  the 
  length 
  of 
  the 
  

   inner 
  toe 
  measured 
  from 
  the 
  tubercle, 
  and 
  7 
  to 
  10 
  

   times 
  in 
  the 
  length 
  of

  heels 
  meet 
  or 
  

   remain 
  narrowly 
  separated 
  ; 
  tibia 
  shorter 
  than 
  the 
  

   foot 
  measured 
  from 
  the 
  outer 
  metatarsal 
  tubercle. 
  

   The 
  tibio-tarsal 
  articulation 
  reaches 
  the 
  eye 
  or 
  be- 
  

   tween 
  the 
  eye 
  and 
  the 
  tip 
  of 
  the 
  snout.

  glandular 
  lateral 
  fold 
  very 
  

   prominent,

  or 
  less 
  of 
  

   bright 
  yellow 
  pigment 
  ; 
  vocal 
  sacs 
  white

  feebly 
  

   pigmented. 
  Iris 
  goldeu,

  black 
  vermi- 
  

   culations. 
  

  

  Males 
  are 
  often 
  of 
  a 
  uniform 
  green 
  colour, 
  without 
  

   any 
  markings 
  ; 
  females 
  are 
  usually 
  more 
  or 
  less 
  

   spotted 
  with 
  black, 
  the 
  spots 
  sometimes 
  confluent 
  

   into 
  longitudinal 
  bands. 
  A 
  light, 
  pale 
  blue, 
  pale 
  

   green, 
  or 
  yellowish-green 
  vertebral 
  stripe 
  is 
  often 
  

   present, 
  and 
  the 
  glandular 
  lateral 
  folds 
  are 
  usually 
  of 
  

   a 
  beautiful 
  gold-colour. 
  A 
  blackish 
  temporal 
  spot 
  is 
  

   sometimes 
  present. 
  Black 
  cross-bars 
  are 
  usually 
  

   present 
  on 
  the 
  hind 
  limbs 
  in 
  the 
  females, 
  more 
  often 
  

   absent 
  or 
  ill- 
  defined 
  in 
  the 
  males. 
  

  

  Sky- 
  or 
  turquoise-blue 
  specimens 
  are 
  rare, 
  and 
  

   must 
  be 
  regarded 
  as 
  individual 
  abnormalities 
  due 
  to 
  

   the 
  absence 
  of 
  the 
  yellow 
  pigment, 
  same 
  as 
  occur 
  also 
  

   in 
  Ili/la 
  arborea, 
  a 
  fine 
  blue 
  specimen 
  of 
  which 
  (var. 
  

   mericlionalis) 
  was 
  exhibited 
  last 
  summer 
  at 
  the 
  Zoo- 
  

   logical 
  Gardens, 
  London.
