  Habits. 
  — 
  Like 
  its 
  congener 
  Bufo 
  vulgaris, 
  B. 
  viridis 
  

   is 
  terrestrial 
  and 
  crepuscular; 
  but, 
  as 
  the 
  breeding 
  

   season 
  is 
  much 
  more 
  prolonged, 
  lasting 
  from 
  April 
  to 
  

   the 
  end 
  of 
  June 
  or 
  the 
  middle 
  of 
  July, 
  owing- 
  to 
  the 
  

   different 
  condition 
  of 
  the 
  ovaries 
  in 
  the 
  females, 
  males 
  

   are 
  found 
  swimming 
  about 
  in 
  the 
  water 
  day 
  and 
  night 
  

   three 
  months 
  in 
  the 
  year. 
  C. 
  Koch 
  mentions 
  having 
  

   found 
  spawn 
  near 
  Frankfort-on-the-Main 
  in 
  August, 
  

   1871. 
  The 
  green 
  toad 
  jumps 
  and 
  swims 
  well, 
  its 
  

   movements 
  being 
  more 
  lively 
  than 
  those 
  of 
  the 
  common 
  

   toad, 
  and 
  very 
  different 
  from 
  those 
  of 
  the 
  natterjack, 
  

   with 
  which, 
  curiously, 
  this 
  species 
  has 
  been 
  united 
  by 
  

   some 
  authors, 
  who, 
  no 
  doubt, 
  had 
  never 
  observed 
  the 
  

   two 
  alive. 
  This 
  toad 
  is 
  often 
  found 
  near 
  the 
  dwellings 
  

   of 
  man, 
  in 
  small 
  gardens, 
  or 
  on 
  waste 
  ground 
  and 
  heaps 
  

   of 
  rubbish, 
  even 
  in 
  the 
  suburbs 
  of 
  large 
  cities, 
  as 
  Berlin 
  

   and 
  Frankfort-on-the-Main, 
  where 
  I 
  have 
  myself 
  come 
  

   across 
  them 
  in 
  such 
  situations. 
  In 
  some 
  parts 
  of 
  

   Germany 
  it 
  has 
  received 
  the 
  name 
  " 
  Hausunke," 
  from 
  

   its 
  abundance 
  in 
  cellars. 
  Young 
  specimens 
  are 
  espe- 
  

   cially 
  conspicuous, 
  hopping 
  about 
  in 
  broad 
  daylight 
  

   throughout 
  the 
  summer. 
  The 
  odour 
  of 
  the 
  cutaneous 
  

   secretion, 
  which 
  is 
  produced 
  very 
  readily 
  and 
  in 
  great 
  

   abundance, 
  reminds 
  me 
  of 
  a 
  linseed 
  poultice. 
  

  

  The 
  voice 
  of 
  the 
  breeding 
  male 
  is 
  louder 
  than 
  that 
  

   of 
  the 
  common 
  toad, 
  but 
  much 
  less 
  powerful 
  than 
  

   that 
  of 
  the 
  natterjack. 
  But 
  for 
  the 
  intensity, 
  it 
  may
