   It 
  is

  that 
  Fitzinger 
  founded 
  

   his 
  Rana 
  dalmatina.

  Habits. 
  — 
  The 
  agile 
  frog 
  well 
  deserves 
  its 
  name; 
  its 
  

   extremely 
  long 
  hind 
  limbs 
  enable 
  it 
  to 
  cover 
  a 
  surface 
  

   of 
  six 
  feet 
  at 
  one 
  leap. 
  The 
  delicate 
  texture 
  of 
  its 
  

   skin 
  and 
  the 
  general 
  slenderness 
  of 
  its 
  build 
  impart 
  to 
  

   this 
  frog 
  an 
  elegant 
  appearance 
  far 
  surpassing 
  that 
  of 
  

   any 
  of 
  its 
  European 
  congeners.
