  bands 
  joining 
  on 
  the 
  breast, 
  or 
  more 
  or 
  less 
  widely 
  

   separated 
  if 
  the 
  male 
  be 
  much 
  smaller 
  than 
  the 
  female. 
  

   The 
  eggs 
  are 
  laid 
  in 
  several 
  masses 
  among 
  water 
  

   plants. 
  The 
  metamorphosis 
  takes 
  place 
  about 
  three 
  

   months 
  later.

  however, 
  not 
  

   of 
  unfrequent 
  occurrence. 
  

  

  In 
  a 
  recent 
  paper 
  on 
  ovipositionin 
  frogs, 
  Nussbaum 
  

   states 
  that 
  B. 
  esculenta, 
  nnlike 
  R. 
  tempovaria, 
  does 
  not 
  

   spawn 
  iu 
  confinement. 
  This 
  is 
  true 
  in 
  a 
  general 
  way 
  

   only, 
  as 
  I 
  have 
  myself 
  obtained 
  eggs 
  from 
  Swiss 
  

   specimens 
  kept 
  in 
  London.
