  upper 
  parts, 
  constantly 
  varying 
  under 
  atmospheric 
  

   influences, 
  often 
  suggests 
  the 
  colour 
  of 
  dry 
  leaves, 
  

   among 
  which 
  the 
  frog 
  is, 
  in 
  fact, 
  not 
  unfrequently 
  met 
  

   with 
  in 
  woods, 
  and 
  under 
  which 
  it 
  seeks 
  shelter 
  when 
  

   pursued. 
  Woods, 
  together 
  with 
  swampy 
  meadows 
  

   and 
  banks 
  overgrown 
  with 
  long 
  grass, 
  constitute 
  its 
  

   usual 
  abode. 
  It 
  is 
  never 
  found 
  in 
  fields 
  or 
  gardens, 
  or 
  

   among 
  roadside 
  brambles 
  and 
  nettles 
  like 
  the 
  common 
  

   frog, 
  which, 
  however, 
  often 
  associates 
  with 
  it 
  in 
  the 
  

   wilderness. 
  The 
  voice 
  is 
  feeble 
  and 
  clear, 
  and 
  may 
  be 
  

   rendered

  Bana 
  agills 
  is 
  found 
  in 
  the 
  water 
  only 
  during 
  the 
  

   breeding 
  season, 
  which 
  falls 
  in 
  France 
  usually 
  three 
  

   or 
  four 
  weeks 
  later 
  than 
  in 
  B. 
  temporaria, 
  between 
  the 
  

   middle 
  of 
  February 
  and 
  the 
  beginning 
  of 
  April, 
  isolated 
  

   individuals 
  spawning 
  exceptionally 
  as 
  tardily 
  as 
  May 
  : 
  

   in 
  Lower 
  Austria, 
  according 
  to 
  Werner, 
  the 
  breeding 
  

   season 
  of 
  the 
  two 
  species 
  coincides, 
  and 
  takes 
  place 
  in 
  

   the 
  latter 
  half 
  of 
  March. 
  The 
  eggs 
  are 
  usually 
  

   deposited 
  on 
  the 
  borders 
  of 
  small 
  ponds 
  or 
  pools 
  in 
  

   flooded 
  quarries. 
  Specimens 
  from 
  Turin 
  sent 
  to 
  me 
  

   the 
  winter 
  before 
  last 
  by 
  my 
  friend 
  Count 
  Peracca, 
  

   spawned 
  in 
  an 
  aquarium 
  out 
  of 
  doors 
  on 
  the 
  20th 
  aud 
  

   21st 
  of 
  February; 
  owing 
  to 
  the 
  cold 
  weather 
  and 
  

   frosty 
  nights 
  that 
  followed, 
  the 
  development 
  of 
  the 
  

   eggs 
  was 
  at 
  first 
  almost 
  completely 
  arrested, 
  and 
  the 
  

   first 
  embryos 
  did 
  not 
  emerge 
  from 
  the 
  mucilage 
  until 
  

   the 
  15th 
  of 
  the 
  following 
  month. 
  

  

  The 
  young 
  leave 
  the 
  water 
  by 
  the 
  end 
  of 
  June 
  or 
  

   beginning 
  of 
  July, 
  rarely 
  as 
  late 
  as 
  the 
  middle 
  of 
  

   August. 
  

  

  The 
  pairing 
  takes 
  place 
  as 
  in 
  JR. 
  temporaria, 
  but 
  is 
  

   of 
  much 
  shorter 
  duration, 
  the 
  females 
  usually 
  resorting 
  

   to 
  the 
  water 
  only 
  at 
  night, 
  and 
  when 
  quite 
  ready 
  to 
  

   spawn. 
  Specimens 
  in 
  embrace 
  are 
  therefore 
  seldom 
  

   observed 
  in 
  the 
  daytime. 
  The 
  males 
  do 
  not, 
  generally 
  

   speaking, 
  show 
  the 
  same 
  genesic 
  frenzy 
  as 
  the 
  common 
  

   frog, 
  seldom 
  seizing 
  females 
  of 
  other 
  species 
  in 
  the 
  

   absence 
  of 
  legitimate 
  mates 
  ; 
  they 
  often 
  hibernate 
  in
